Piketty & Public Health

Pump Handle - July 21, 2014

by Anthony Robbins, MD, MPA

I first heard the name Thomas Piketty on a trip to France.  Now his immense book, Le capital au XXIe siècle (Capital in the Twenty-First Century) sits on my bedside table (in both the original French and the English translation).  It is a best seller in the US and in France. I have read reviews (here, here), attacks, defenses, and other essays that take off from Piketty’s work. I even had the opportunity to hear him live, addressing a class at MIT.

Having learned Piketty’s major observations and arguments with the MIT students and followed the debate about his work, I sheepishly admit that I have barely cracked open the book. Perhaps I overestimated my capacity to read the book. Could a book so large and dense ever have been bedtime reading?

This has not stopped me from thinking, based on his methods and conclusions, Piketty might have something to offer us in public health.  He describes how over the last two centuries, as income flowed to the richest people, the distribution of wealth in industrial societies has become increasingly concentrated in a very small minority–increasing wealth inequality.  There was one brief period, from the 1940s to the 1980s, where wealth inequality declined, but Piketty suggests that this was an historical aberration, not the long-term trend.  He predicts increasing wealth inequality in the 21st Century, a feature of capitalist economies, unless we do something about it.

Public health scholars have concluded that environmental factors–both the physical and social environments–affect health.  They have imported the word determinant from mathematics to describe these causal situations. They have also chosen to use the adjective “social”, although I don’t think they means to exclude physical exposures like housing and workplaces. And since the Report on the WHO Commission on the Social Determinants of Health, researchers are more attentive to what influences the health of populations.  This is a salutary trend, as it constitutes a countervailing force against the tendency to attribute health to medical care effectiveness and lack of health to medical care deficiencies–a very narrow view.

To study social determinants of health, most researchers have compared people exposed to different environments, often using income as a variable.  Because it is easier, these studies usually look at different populations at one time in history. The studies are cross-sectional, not longitudinal (over time).

If we adopted Piketty’s research strategy and focused on changes in health and in social determinants over time, would we be able to learn more about the causes of health inequality?  Surely more has changed over time than the medical care system. And just as Piketty urges policies that alter wealth directly, such as wealth taxes, to achieve a more equitable distribution of wealth, public health advocates would be advised to urge policies that attack the most unhealthy aspects of our societies’ environments.

Here I make a plea for public health leaders to avoid having public health get lost in the term health systems, where the public immediately thinks medical care.  Surely we must attend to workplaces and employment, housing and the living environment, and toxic and physical exposures throughout society.  These exposures are rarely spread evenly across the population.  Following changes over time in both health and exposures may encourage policies that bring more health in the future.  It may be a powerful antidote to the conventional thinking that usually attributes inequality in health to unequal access to medical care.

Mapping the lives and deaths of workers: An emerging way to tell the story of occupational health and safety

Pump Handle - July 18, 2014

When Bethany Boggess first debuted her online mapping project, she didn’t expect it to attract so much attention. But within just six months of its launch, people from all over the world are sending in reports and helping her build a dynamic picture of the lives and deaths of workers.

The project is called the Global Worker Watch and it’s quite literally a living map of worker fatalities and catastrophes from around the globe. When you go to the site, you’ll see a world map speckled with blue dots, each representing a reported occupational death, illness or disaster. Here are just a few I randomly clicked on: In March in Pakistan, four workers died and 18 were injured when a gas cylinder exploded at a gas company. Also in March in Gujarat, India, two workers died of silicosis, an occupational disease caused by the inhalation of silica dust. Three workers have died in the mines of Coahuila, Mexico, since January. In February, a worker at an Iron County mine site in Utah died after getting trapped on a conveyer belt. Just a few days ago, a worker in the United Kingdom died after falling from an electricity tower. And in May, police in Cambodia opened fire during a labor protest, killing four people.

“Obviously, I’m only capturing the tip of the iceberg,” said Boggess, a 26-year-old epidemiology student at the University of Texas School of Public Health in Austin. “But if I’m just one person and I can do this in six months…then with more and more people contributing, we can get a much more complete and accurate picture (of worker deaths and injuries).”

The idea for Global Worker Watch grew out of Boggess’ experience investigating the global supply chain in the aftermath of the Rana Plaza building collapse in Bangladesh in 2013 that killed more than 1,000 people and injured thousands more. The building housed a number of garment factories and nearly all those who died in the collapse were garment workers. In the wake of the disaster, Boggess began working with data analysts in the United Kingdom to figure out which U.S. and U.K. companies sourced their products from factories in Bangladesh. In particular, Boggess analyzed several million import and export records from Wal-Mart and it piqued her interest in working with unusual data sets and in presenting data in visually appealing mediums. Shortly after the Bangladesh project, she partnered with an Austin-based worker center, Workers Defense Project, to map incidents of wage theft and worker injury using weekly reports from OSHA. Both experiences as well as the skills she’s gained as an amateur computer programmer and hacker eventually led her to build Global Worker Watch and its interactive maps.

Here’s how it works. Boggess finds data for the maps from three main sources: news sources using Google Alerts, government data (“Kind of a pain and not always useful,” she tells me), and people from all around the world who submit stories and data directly to Boggess through the website. Boggess is fluent in Spanish and Italian and can read and understand French, so she’s able to map stories and data arriving in those languages. For right now, language is definitely a hurdle in creating more complete and accurate maps, she said. But she hopes that as more people hear about the project and want to participate, it’ll become less of a barrier.

When a worker incident comes in, Boggess typically gets it on the map within a week, through sometimes it’s within hours. Sometimes, the story behind the dot on the map is somewhat vague — with little known about the workers involved or even the name of the workplace — while others are much more detailed, listing the worker’s name, age, gender, cause of death and the name of the company where he or she worked. Boggess told me that about 10 percent to 15 percent of the mapped data come directly from people contacting her with reports of worker deaths. The Global Worker Watch site also offers visitors its data in the raw as well as a gallery of recent and historical photos of workers from around the world.

“I wanted to put a face to this,” she said of the photo gallery. “The maps are nice but there’s no human face to them.”

Boggess said she doesn’t know of other projects attempting to map worker deaths worldwide. However, the idea of using mapping to more easily illustrate a public health problem isn’t entirely new. For instance, HealthMap mines the Internet to map disease outbreaks and emerging public health threats and Google Flu Trends does the same with flu activity. (We’ve written about HealthMap here.) In the worker safety arena, CPWR – The Center for Construction Research and Training launched its Fatality Map in 2011 and may have been the first to use the mapping technique in an occupational health and safety application.

Fatality Map, which is part of the center’s falls prevention campaign, maps overall construction fatalities and fatal construction falls in the United States. Data for the maps are collected from ongoing OSHA investigations and supplemented with media reports, said Gavin West, a research analyst at the center, which grew out of a series of cooperative agreements with the National Institute for Occupational Safety and Health and is dedicated to generating research and training resources to promote safe working conditions for construction workers. Each pinpoint on the Fatality Map tells the story of a construction fatality. For example, in April 2013, two workers in Hendersonville, Tennessee, died after being pinned underneath a section of a concrete block wall that collapsed during construction of a new building. Fatality Map data are collected in real time, and the online maps are updated quarterly.

West told me that in 2011, the mapping project was able to capture 78 percent of official construction-related fatalities and 69 percent of fatal fall numbers when compared to data from the Bureau of Labor Statistics. In 2012, the maps captured 74 percent of overall fatalities and 68 percent of falls. West said that while Fatality Map isn’t the best tool for making state-based comparisons, it can show — “very plainly” — where more construction workers are dying and falling on the job.

“(The maps) help bring life to the data instead of just looking at the numbers,” West told me. “The visual aspect and the ability to interact help draw some attention to the problem.”

Fatality Map also lets visitors access its raw data so that people can create even more specific profiles of construction-related deaths. For example, Chris Trahan, the center’s deputy director, told me that the open data was recently used to research fall-related fatalities among industrial painters in California. Trahan said in addition to raising awareness about construction worker deaths, Fatality Map is also a useful training tool. She said she’s heard from safety trainers who use the maps to drive home lessons and reinforce safety messages — “it’s become another tool in their toolbox.”

“We hope we can put a face to the numbers,” Trahan said.

Back in Austin, Boggess said most of the responses to Global Worker Watch have been positive. She said she’s received a particularly excited response from corporate transparency activists, such as United Students Against Sweatshops. The experience is also providing some fascinating insights and anecdotes.

For instance, she said that “Spain is incredible, they report everything — every time a worker gets a scrape, it’s reported.” Interestingly, she said she often learns about a U.S.-based incident involving an immigrant worker in news reports from the worker’s native country before reading about it in an American media outlet. Boggess noted that the lack of data also tells a compelling story. One quick glimpse at Global Worker Watch and you’ll notice hardly any blue pinpoints in the entire African continent. Partially that’s because of the language barriers that Boggess hopes to overcome as more people take part; but it’s also because of insufficient workplace oversight.

Boggess has received some criticism about the accuracy of Global Worker Watch. But she believes that the more open her site is the more likely people will help verify stories of worker conditions. And once you start clicking on the little blue dots and reading about workers dying from suffocation, workplace violence, chemical exposure, drowning, building collapse — you just can’t stop, which seems to be exactly the point.

“I hope the map will help consumers and the public realize just how important it is for workers to be treated with some basic human rights,” Boggess said. “I hope I can visually show how big the issue is and how it shouldn’t be ignored.”

Germany Tops Energy-Efficiency Ranking and U.S. Scores Near Bottom

Yale Environment 360 - July 18, 2014
Germany tops a new energy efficiency ranking of the world’s major economies, followed by Italy, China, France, and Japan, according to the American Council

Energy-efficiency rankings for an Energy-Efficient Economy (ACEEE). The United States ranked 13th out of 16 nations, behind countries such as India, China, and Canada, although new carbon pollution standards proposed this June for existing power plants would be a major stride in the right direction, the ACEEE said. The group also admonished Australia, which ranked 10th, for demonstrating "a clear backward trend" in adopting energy efficiency measures. Germany took the top spot largely due to regulations it has imposed on commercial and residential buildings. And China, despite lax enforcement of building codes, uses less energy per square foot than any other country, the analysis found.

OSHA gave me a reason to visit at Recovery.gov

Pump Handle - July 17, 2014

Flashback to February 2009. The economy was in the tank. President Obama was marking his second month in office. Congress passed and the President signed H.R. 1, the “American Recovery and Reinvestment Act of 2009,” which authorized $800 billion in government spending to stimulate the economy. $800 Billion is not chump change, and who would get the money was on people’s minds. The President understood

“It’s your money. You deserve to know where it’s going and how it’s spent.”

His answer: the Recovery.gov website, which launched on February 17, 2009.

I never had a reason to visit the site until this week.  The nudge came from an OSHA news release out of Coolville, Ohio. The agency announced citations for a willful and eight serious violations issued against Morlan Enterprises a firm doing cell tower work in Meigs County, Ohio.  An OSHA inspector observed two workers climbing up a 195-foot communication tower without adequate fall protection. The news release notes:

“Morlan Enterprises was contracted by New Era Broadband Services of Coolville to perform tower construction and antenna installation services at 20 locations in the Meigs County area. The New Era Broadband construction project is being funded by a grant, administered through the U.S. Department of Agriculture — Rural Utilities Service, to bring broadband services to underserved communities in the area.”

I didn’t know what kind of grant the firm might have received so I first poked around on the USDA’s website. I got frustrated after a while and picked up the phone. I called the USDA’s Rural Utilities Service (RUS) to ask if the names of grant recipients are posted on the agency’s website. After getting bounced around a few times, I learned, they aren’t. The stimulus money website is unique, at least as far as RUS grants and loans are concerned.

Well maybe the grant referred to by OSHA was part of that $800 billion in stimulus money? Afterall, the bill authorized $7.2 billion in spending to expand broadband and wireless Internet access. My reason to visit Recovery.gov had arrived. Here’s what Recovery.gov tells me about New Era Broadband and Morlan Enterprises:

  • In September 2010, New Era Broadband was awarded a grant for $2.2 million and a loan of $739,000 under the stimulus program.
  • The firm has been paid to-date $1.87 million on the grant and $623,000 for the loan.
  • The project is more than 50% complete.
  • Morlan Enterprises appears on the Recovery.gov website as a vendor providing consulting services to New Era Broadband. The website shows payments to Morlan Enterprises totaling $3,938.

A few thousand dollars is small potatoes in the stimulus-money scheme of things, but not necessarily meaningless when picking apart of worker safety problem.  And there’s a big worker safety problem in the cell tower industry. A 2012 analysis by ProPublica calculated a death rate for cell tower workers that was more than 10 times that for construction workers. And holding companies responsible for the deaths and injuries has floundered. As ProPublica noted

“cell phone carriers and tower owners have insulated themselves from legal and regulatory liability for on-the-job injuries by delegating this work to layers of subcontractors.”

OSHA’s been trying to get a handle on the problem.

The agency told its inspectors last year that if they became aware of cell tower work in their area, they should go and inspect the site.  Inspectors were also instructed to obtain any relevant contracting agreements that show business relationships between the tower owner, wireless carrier, repair service companies, etc.  That’s an important step needed to identify who is influencing how the job is being done, and more importantly, how decisions will affect safety. But with deaths of cell tower workers continuing, OSHA put the industry on notice in February: It would consider classifying violations of its fall protection standard as “willful.”  OSHA’s Columbus, OH area office is keeping the agency at its word: (1) a willful violation issued to Morlan Enterprises, and (2) documentation of who hired the firm for the work. In this case, at the top of the contracting food chain is the USDA.

What I don’t know (but OSHA probably does) is whether this particular project—-the subject of the OSHA inspection—-was funded with the stimulus money, or another USDA grant. The RUS has been funding telecommunication improvements for years.  USDA Secretary Tom Vilsack announced recently the availability of $13 million to fund broadband projects in unserved areas.  The announcement notes:

“Since it was created in 2003, USDA has approved more than $142 million in more than 240 Community Connect projects to bring broadband service to rural communities that lacked it.”

Seems that USDA is part of the tangled web of players in the cell industry.  I had no clue.

Companies that apply for these USDA grants are asked to provide evidence that they comply with certain federal statutes. The USDA’s most recent announcement for telecommunication grants mentions laws on lobbying, a drug-free workplace, and flood hazard precautions.  Maybe it’s time to specifically mention compliance with OSHA regulations, including those on fall protection and a 100 percent tie-off rule.

Boston's natural gas leaks "fugitive" methane emissions associated with the nation's aging infrastructure. The Environmental Defense Fund partnered with Google Street View to map leaks in the nation's natural gas system, using cars equipped with air-quality sensors that collected millions of readings across Boston, Indianapolis, and Staten Island. The analysis found thousands of methane leaks in highly-populated areas — particularly in Boston, where half of the pipes are more than 50 years old and leaks were detected every few blocks. Although the leaks did not appear to pose explosion hazards, their prevalence highlights the potential for fugitive methane — a greenhouse gas with an impact 20 times that of carbon dioxide — to contribute to global warming.

Politics and Education Affect When People Search for Climate Information, Study Finds

Yale Environment 360 - July 16, 2014
People across the United States search the Internet for information on climate change when they experience unusual or severe weather events, but the timing of their searches differs based on political ideology and education levels, according to research published in the journal Climatic Change. An analysis of Google searches and weather patterns between 2004 and 2013 found that Democratic-leaning regions and those with higher education levels were more likely to seek information about climate change when average summer temperatures were above normal, whereas those in Republican and less educated areas sought climate change information when they experienced extreme heat. Searches peaked during weather consistent with climate change as well as during cold snaps, the study found. This could indicate that people who observe unusual extreme weather conditions are genuinely interested in learning more about climate change, or that climate deniers, when experiencing unusually cool weather, go online to confirm their skeptical views, the researcher speculated.

Reynolds in Talks to Acquire Lorillard in Merger of Tobacco Rivals

Pump Handle - July 16, 2014

By Anthony Robbins, MD, MPA

So screams a headline in the New York Times business section on July 12, 2014.  Two of the three tobacco companies in the $100 billion US market plan to merge.

Fifty years after the Surgeon General’s first report on Tobacco and Health, the US tobacco industry is working to grow its profits. Will the universal consensus that cigarettes kill have any effect on a government decision whether to intervene in the proposed merger?  The Government usually gets involved when a merger would reduce the number of sellers in the market, possibly reducing competition and raising prices. But does it matter whether society needs the product or whether it damages health. I know of no precedent for invoking health considerations.

Anti-trust laws are likely to be the basis for a government review of the proposed merger. Under anti-trust theory, competition helps consumers by lowering prices… but that hurts consumers of cigarettes.  If competition makes it less expensive for Americans to feed their deadly addictions created by tobacco companies, should the same government that has found cigarettes to be killers decide how to act without considering health, based instead on an assessment of competition and cigarette prices? Surely the two companies who want to merge will claim, as companies always do, that the merger will not result in higher prices.  I suspect they will not mention or be proud that today’s unconscionable level of damage to health will be maintained.

At the very least the Department of Justice’s anti-trust division should request a simple study.  What effect will the merger have on the health of the American population?  The Office of the Surgeon General of US Public Health Service could carry out such a study.  The same data that the two tobacco companies and their opponents will provide to the Anti-trust Division to show that the merger will or will not maintain, raise or lower prices, and thus “benefit” or “harm” consumers can be available to the Surgeon General.  It is not hard to extrapolate from data on projected prices, sales, and use to estimate the health effects.  The public health goal should be to make sure any action proposed by tobacco companies is seen as a way to advance a business that harms people.

Perhaps a faint silver lining is hiding in the merger plans, as both companies are seeking to strengthen their footing in the electronic cigarette business. (Remember, studies have not found e-cigarette vapor to be safe.) How eager are they to transfer America’s collective addiction from the tar-containing and cancer-causing smoke of burning tobacco to the tar-free vapor in e-cigarettes?  Would they agree, as part of a merger approval, to close their tobacco businesses entirely by a date certain?

As we discuss this merger, it will be important to remember that our public health goal is an endgame, where tobacco, that serves no useful purpose, disappears from our environment and society.

Occupational Health News Roundup

Pump Handle - July 15, 2014

Serious health problems are driving workers at a car part manufacturer in Alabama to call for a union. In an in-depth article for NBC News, reporter Seth Freed Wessler investigated occupational exposures at the Selma-based Renosol Seating plant, where workers make foam cushions for Hyundai car seats and headrests. According to the story, at least a dozen current and former employees report sinus infections, chronic coughs, bronchitis, shortness of breath and asthma since working at the factory. The story begins with worker Denise Barnett:

Denise Barnett was thankful seven years ago when she started a job at the Renosol Seating plant, one of 90 hourly workers making foam cushions for Hyundai car seats and headrests.

“Here in Selma, a job is hard to find,” said Barnett, 37. In Dallas County, where Selma is the county seat, the unemployment rate is about 12 percent, and 60 percent of children live below the poverty line.

Before landing this position, Barnett, who like most Renosol workers is African American, worked at a gas station for minimum wage. For Selma residents like her, a job at Renosol—$11 an hour plus healthcare—is like gold.

But in early 2013, Barnett developed a nagging cough that kept her up at night. One evening last July, Barnett came home after picking up her two young boys from her sister’s house and had a serious coughing attack. “I made the kids run back into the car and rushed to the hospital,” she said. When Barnett arrived in urgent care, she said, she could barely breathe and spent two nights in the hospital.

“They say I have asthma,” said Barnett, who said she’d never been a smoker and now uses two inhalers and a nasal spray. “I never had that before.”

Wessler reports that Barnett and other sick workers have a theory about what’s causing the respiratory complications — a chemical called toluene diisocyanate, or TDI, which is used to make the car seat foam and is a documented cause of work-induced asthma. The story notes that companies are largely left on their own to regulate exposure to TDI. OSHA head David Michaels told Wessler that “OSHA’s workplace exposure limits for many chemicals are out of date and not adequately protective.”

Perhaps not surprisingly, the plant’s parent company, Lear Corporation, claims the Selma plant is a safe environment for employees. So in conjunction with occupational medicine researchers at Yale University, NBC News coordinated independent testing of workers’ TDI exposure. Of the six workers whose blood had been tested at the time the article was published, four showed exposure to TDI and one showed a low level of exposure. Wessler quoted one of the researchers:

“This is a high frequency of exposure, and it’s cause for concern,” said Adam Wiznewski, PhD, senior research scientist at Yale. He said that the workers may not be representative of the rest of the Renosol’s 90-person hourly workforce, but that exposure in even four workers indicates a problem. “The company definitely needs to be looking at its industrial hygiene, and they probably need to look into personal protective equipment for workers, and medical surveillance of health issues.”

In other news:

ProPublica: In collaboration with Univision, reporter Michael Grabell wrote about the death of Janio Salinas, a 50-year-old temp worker who lost his life after being buried alive in a mountain of sugar at a sugar plant in Pennsylvania. Grabell reports that federal investigators recently found that just two weeks prior to the incident, a safety device that would have saved Salinas’ life was removed because a manager believed it was slowing down production. The company was fined just $18,000 for Salinas’ death. In a related article, Grabell reported that Sen. Robert Casey, D-Pa., has written OSHA’s director about the growing number of workplace injuries and fatalities involving temporary workers. The articles are part of ProPublica’s “Temp Land: Working in the New Economy” series.

He started the article with a housing example that’s sadly not surprising to advocates in the field: A farmworker and her kids living in a decommissioned walk-in freezer. In interviewing Bobbi Ryder, CEO and president of the National Center for Farmworker Health, about the type of housing farmworkers need to stay healthy and maintain food safety on the job, the answer was simple: “They need the same things that you and I need. Clean running water for drinking and bathing, access to washers and driers so when they come out of the field after a hard day’s work they can wash their clothes, enough space so communicable diseases aren’t a problem.”

California Agriculture Relying Too Heavily on Groundwater Reserves in Drought

Yale Environment 360 - July 15, 2014
California's agriculture industry is relying too heavily on groundwater to irrigate drought-stricken farmlands — a trend that will not be sustainable long-term, according

Central Valley orchard to a study by the University of California, Davis. The drought, which is the third most severe on record, is responsible for the greatest water loss ever seen in California agriculture, with river water for Central Valley farms reduced by roughly one-third, the study found. Groundwater pumping will likely replace most river water losses, and some areas have more than doubled their pumping rate over the previous year. If the drought continues for two more years, the report says, groundwater reserves will continue to be depleted to replace surface water losses and pumping ability will slowly decrease, which could affect crop production. So far in the current drought, 428,000 acres of cropland — roughly 5 percent — has been made fallow across the Central Valley, Central Coast, and Southern California.

Human Activity Has Caused Long-term Drought in Australia, Model Shows

Click to Enlarge

Projected rainfall trends in Australia increases in man-made greenhouse gas emissions and ozone depletion, according to research published in Nature Geoscience. Simulating both natural and man-made climate effects, scientists showed that the decline in rainfall is primarily driven by human activity. Rises in greenhouse gas emissions and thinning of the ozone hole have led to changes in large-scale atmospheric circulation, including a poleward movement of the westerly winds and increasing atmospheric surface pressure over parts of southern Australia. This has led to decreased rainfall, the study said. The drying is most severe over southwest Australia, where the model forecasts a 40 percent decline in average rainfall by the late 21st century, with significant implications for regional water resources.

EPA’s trichloroethylene (TCE) risk assessment: Will it succeed in protecting workers?

Pump Handle - July 14, 2014

What do these places have in common: Camp Lejeune in North Carolina; Mountain View, California, where Google headquarters are located; Endicott, NY – the birthplace of IBM; and 389 Superfund sites in at least 48 states plus Puerto Rico and the Virgin Islands? All are contaminated by trichloroethylene (TCE), a volatile organic compound classified as a carcinogen that’s been widely used as a solvent and degreaser in large-scale industrial processes, small commercial shops and in some products used by individual consumers. On June 25th, the Environmental Protection Agency (EPA) released its final risk assessment for TCE, the first such report to be completed for any of the 83 “work plan” chemicals EPA identified in 2012 as sufficiently hazardous to warrant priority assessment. It is the first chemical risk assessment EPA has completed under the Toxic Substances Control Act (TSCA) – the federal law that regulates chemicals in commerce – since it evaluated asbestos in 1986.

EPA’s TSCA risk assessments focus on uses of the chemicals that fall under EPA’s jurisdiction (EPA doesn’t regulate food contact chemicals or those in cosmetics, for example) that have what the agency considers significant potential for human and/or environmental exposure. EPA explains that “If an assessment indicates significant risk, EPA will evaluate and pursue appropriate risk reduction actions.” What those actions may be is not specified. So an EPA risk assessment doesn’t lead directly to specific restrictions, but completion of a TSCA risk assessment is a prerequisite for further EPA action if high hazard is found.

“EPA calls on Congress to enact legislation that strengthens our current federal toxics law,” said Jim Jones, EPA assistant administrator for chemical safety and pollution prevention, in a press release. “Until that time,” said Jones, “we are using the best available science to assess and address chemical risks of TCE that now show that it may harm human health and the environment.” TCE is one of the country’s most common groundwater contaminants and has been detected in ambient air in every state. EPA has noted that virtually all TCE in the environment comes from anthropogenic sources. Given the chemical’s toxicity, the agency has set as a safety goal for TCE in drinking water, zero parts per billion.

The EPA risk assessment does not focus on the widespread environmental exposures to TCE, however, but on health risks to workers in small commercial operations that use TCE-containing products (including dry cleaners where TCE is used as a stain remover) and to consumers using TCE-based degreasers and fixatives in art and other craft, hobby and DIY projects. Nothing regulatory has been announced but the EPA will hold a public workshop on July 29 and 30 to discuss alternatives to these uses of TCE and other “risk reduction approaches.”

“In the meantime, EPA recommends that people take precautions that can reduce exposures, such as using the product outside or in an extremely well-ventilated area and wearing protective equipment to reduce exposure,” wrote the agency in its June 25th press release.

A volatile and hazardous substance

TCE exposure, primarily through inhalation, has long been linked to cancer of the kidney, liver and immune or lymphatic system. It has also been linked to adverse impacts on development and on immune, neurological and reproductive system health. Exposure, occupational and environmental, has also been linked to low birth-weights and fetal cardiac defects, among other adverse health effects. In the 1980s and earlier, TCE was often used at such volume industrially – including by the electronics industry in circuit board and semiconductor production – that it was stored in underground tanks. Leaks and other unintended releases at many of these tanks sent TCE into surrounding soil and groundwater resulting in ongoing contamination that has lasted for decades. TCE is also used as a chemical intermediate in producing numerous other chemical products including some refrigeration gases, insecticides, flame retardants and polyvinyl chloride (PVC), as well as products that include disinfectants, perfumes, dyes, soaps and pharmaceuticals. Exact current US production figures are not available due to confidential business information claims but the EPA assessment says that 224.7 million pounds were reported to the EPA in 2012 and about 255 million pounds are used here in 2011 when global consumption was 945 million pounds.

TCE is not bioaccumulative and not thought to have high toxicity to aquatic organisms, but it can easily move through soil and groundwater and thus last for years underground. Epidemiologists and public health officials have documented clusters of birth defects and cancers that may be associated with these exposures. Breathing TCE in confined indoor spaces is considered among the most harmful types of exposure.

Because it is so volatile, TCE vapor can rise up from soil under foundations and infiltrate buildings – including homes – as it has done in communities across the US (a process known as vapor intrusion), exposing occupants to toxic but often undetectable fumes. Whole communities have been affected by such vapor intrusion. Endicott, NY sits atop a 300-plus-acre plume of TCE-contaminated groundwater – a situation dating back decades. NIOSH research has found significantly elevated rates of certain cancers including leukemia, non-Hodgkin lymphoma and kidney cancer among workers there exposed to TCE. A 2005 New York State Department of Health study also found high rates of certain birth defects and cancer, including kidney and testicular cancer, among people living in this area. TCE vapor intrusion also recently cropped up at Google’s Mountain View, California campus that is located where electronics industry plants and military aerospace operations spilled TCE into the soil.

Given these hazards, promoting ways to reduce use of TCE-containing products and to eliminate TCE exposure would seem to be a sensible response.

Industry objections

But within hours after EPA released its assessment on June 25th, Senators David Vitter (R-LA), Mike Crapo (R-ID) and James Inhofe (R-OK) – all members of the Senate Environment and Public Works (EPW) Committee – sent a letter to EPA Assistant Administrator Jim Jones, questioning the EPA’s method of conducting risk assessments, the EPA’s scientific standards and suggesting that lead scientists on the assessment had committed “scientific misconduct” and “fraud,” and that EPA “mismanagement” had compromised studies used in the assessment.

“As there continue to be significant challenges with your Agency’s ability to produce credible sound science in a transparent manner, we will continue to investigate OCSPP [Office of Chemical Safety and Pollution Prevention], its scientific findings, and the processes used for promoting individuals to senior-level positions, who ultimately have decision-making authority on chemical risk assessments,” wrote the senators who – with other Republican colleagues in the House and Senate – have previously questioned EPA’s assessment of formaldehyde, inorganic arsenic and endocrine disruptors. Vitter’s defense of formaldehyde has taken a similar tack

In the past year, the American Chemistry Council (ACC), whose members include companies that manufacture TCE (Dow Chemical and Axiall), has also written to the EPA, outlining its criticisms of the agency’s approach to its TCE TSCA risk assessment. Among these, spelled out in a March 2013 letter from ACC’s Director of Regulatory Affairs to EPA, is that EPA’s assessment should “explicitly address the authority of the Occupational Safety and Health Administration (OSHA) to regulate occupational exposures” and coordinate with OSHA to avoid any conflict or confusion.

The Halogenated Solvents Industry Association (HSIA), a trade association whose members also include TCE manufacturers, wrote in its comments to EPA on the draft assessment: “…it would be a clear overreach of EPA’s authority for it to assert the power to regulate to protect workers in occupational settings when this responsibility has been delegated by Congress to the Occupational Safety and Health Administration…” The HSIA also takes issue with the entire premise of the EPA assessment, saying that EPA has not met the standard of showing there is “unreasonable risk” to health from the TCE exposures under consideration and therefore would be lacking authority to act as it is doing under TSCA.

The HSIA also questioned EPA’s authority to consider products that might be used in art projects – spray fixatives for example – saying that no further action is warranted given the warning labels issued under the Federal Hazardous Substances Act (FHSA) and by the Consumer Product Safety Commission. That EPA is also considering the risks of TCE to “bystanders” who might be exposed by the use of the products covered in the assessment, HSIA found to be without merit, saying this wouldn’t apply to products used occupationally.

Ongoing effort to cast doubt

Center for Progressive Reform senior policy analyst Matt Schudtz sees the Senate EPW Republicans’ and industry response to the TCE assessment as part of an ongoing pattern of action to stall and question EPA and other federal agency science on widely used but toxic chemicals. The EPA Integrated Risk Information System (IRIS) assessment of formaldehyde has come under similar attack as have the National Toxicology Program’s (NTP) assessments of formaldehyde and styrene in its Report on Carcinogens. He characterized the June 25th letter from Sens. Vitter, Crapo and Inhofe to EPA as a “short term” effort in a “long game” aimed at casting doubt on now well-established science on these chemicals, including TCE.

As the salvo of criticism of EPA’s chemical risk assessments and accusations against EPA continue, those losing out are workers and other individuals who continue to be exposed and the thousands of “by-standers” exposed to TCE environmentally as its large-scale use persists.

U.S. Census: One in four U.S. residents live in communities of concentrated poverty

Pump Handle - July 11, 2014

Last year, the U.S. Census reported that record numbers of people were living in poverty. In fact, the 46.5 million Americans living in poverty as of 2012 was the largest count since the Census began measuring poverty more than 50 years ago. But along with overall poverty numbers, the Census recently reported that concentrated poverty is up, too — and that’s worrisome because it means that more people may face even greater barriers and fewer opportunities to moving out of poverty.

The Census Bureau designates any census tract with of a poverty rate of 20 percent or more as a “poverty area.” In a new report based on data collected during the American Community Survey, researchers found that concentrated poverty is returning to peak levels of the past. While the percentage of people living in poverty areas fell by nearly two percentage points between 1990 and 2000, from 20 percent to 18.1 percent, it grew by more than seven points between 2000 and 2010, from 18.1 percent to 25.7 percent. In all, the number of people living in poverty areas grew by about 56 percent, the Census reported in “Changes in Areas with Concentrated Poverty: 2000 to 2010,” which was released June 30. The sheer number of people living in poverty areas grew from 49.5 million people in 2000 to 77.4 million in 2010.

So, why does it matter that more people are not only living in poverty, but also in communities of concentrated poverty? Because it presents additional burdens to low-income families. As the Census report notes, poverty areas tend to struggle with poor housing conditions, few employment opportunities and higher crime rates. In other words, studying the spatial dimension of poverty “underscores the difficulty that people have in escaping poverty,” said Dan Lesser, director of economic justice at the Sargent Shriver National Center on Poverty Law.

“It’s important to look beyond the overall poverty rate,” Lesser told me. “(Concentrated poverty) can exacerbate long-term trends in poverty and income inequality. The more you’re surrounded by poverty — well, it just makes everything harder.”

Looking beyond the overall concentrated poverty numbers, the Census Bureau found a number of demographic trends:

• Residents of high poverty neighborhoods are more demographically diverse than they’ve been in the past.

• The number and percentage of people living in poverty areas increased within all three age groups, among children, adults between the ages of 18 and 64, and people ages 65 and older.

• The number of people living in poverty areas increased among all ethnic and racial groups, with the largest increase among whites and the smallest among Asians. A considerably larger share of blacks lived in poverty areas when compared to other population groups.

• Nearly 6 million more children were living in poverty areas in 2010 than in 2000.

• The proportion of people living in poverty areas increased across all educational levels, with the number of people with an associate’s degree or higher more than doubling. However, the largest increase was experienced among people with a high school education or less.

• Between 2000 and 2010, the proportion of poor employed people living in poverty areas went up by 12 percentage points.

• Among all types of family households, the largest proportion of those living in poverty areas were those headed by women, with no husband present.

• The Northeast was home to the smallest increase in the number of people living in poverty areas, while the Midwest experienced the largest increase.

Not surprisingly, concentrated poverty often results in a variety of negative impacts, especially for children, said Rolf Pendall, director of the Metropolitan Housing and Communities Policy Center at the Urban Institute. For example, local schools ultimately suffer from less tax support, fewer resources and higher staffing turnover, he told me. It’s an important point, as education is not only connected to better employment opportunities later in life, it’s consistently tapped as a key determinant in greater life expectancy, better health outcomes and less disability.

Besides the impact on education, areas of concentrated poverty also tend to attract less investment from the private sector, goods and services tend to be more expensive (for instance, a corner store typically charges more for food than a grocery store that buys in larger bulk), and there’s a mismatch between those who need jobs and available employment opportunities.

“You can expect concentrated poverty to go up when overall poverty goes up,” Pendall told me. “When more and more people become poor, more neighborhoods become poor and so more people are tipped into living in poor areas. It’s like this rising tide of poverty…and soon it becomes more likely that you’ll be living below the water line.”

Pendall said that conditions may be especially burdensome for residents living in rural areas of concentrated poverty. As opposed to metropolitan areas with mass transit and high density, the characteristics of rural communities — low density, limited transportation options, less access to health care and fewer housing options — can make it “exceptionally difficult” to pull together the resources needed to overcome poverty, Pendall said.

“It’s really rural areas that are getting left behind a lot of the time,” he said.

Jennifer Clary, a senior research associate with Economic Security Projects at the Heartland Alliance’s Social IMPACT Research Center, noted that concentrated poverty data underscores the “idea of compounded disadvantage.” Like Pendall, Clary pointed to school support that’s largely tied to local property taxes and is negatively impacted when poverty rates rise.

“For those living in areas of concentrated poverty, they’re dealing with issues of double burden,” she told me. “There’s a variety of factors that are associated with being in communities of high poverty that limit the opportunity to move out of poverty.”

Both Clary and Pendall pointed to housing policy, which has been a historical driver of concentrated poverty, as one way to drive down the Census numbers and alleviate some of the negative impacts of poverty. For example, Pendall said policies that encourage mixed-income housing communities could be especially useful in helping single mothers find affordable rentals in neighborhoods without high concentrations of poverty.

Of course, another way to address rising poverty is through better wages and specifically by raising the federal minimum wage, which right now sits at just $7.25 an hour.

“Low-wage workers and those living on the minimum wage are consumers, too,” Clary said. “When you put more money into their pockets, they’re going to spend those dollars in their local communities. Not only would we be helping low-wage families meet more of their basic needs and weather tough times, we’d be making a contribution to the community. …We certainly know that there are other job quality issues (we need to address) and while wages aren’t everything, they’re an important piece of the puzzle.”
