Walmart joins ranks of retailers pulling toxic paint strippers from shelves – when will EPA follow suit?

Sarah Vogel, Ph.D.is Vice-President for Health.

Today, Walmart announced that it will stop selling paint strippers containing methylene chloride or N-methylpyrrolidone (NMP) in stores by February 2019 – making it the first general merchandise retailer to take such action.  Walmart’s announcement follows the strong leadership demonstrated by Lowes, Home Depot, and Sherwin Williams, all of which have committed not to sell methylene chloride- and NMP-based paint stripping products by the end of the year.  Importantly, Walmart’s action goes beyond its U.S. stores, including those in Mexico, Canada, and Central America, as well as their online store.

The announcement signals an important step by Walmart to better protect consumers from dangerous paint strippers. Methylene chloride is highly neurotoxic and acutely lethal. The chemical is responsible for over 50 reported deaths from acute exposure over the last 35 years – though many more likely have gone unreported. NMP is linked to fetal development problems, including low birth weight and birth defects.

EDF has advocated for several years for the Environmental Protection Agency (EPA) to ban both methylene chloride- and NMP-based paint strippers, using its enhanced authority under the reformed Toxic Substance Control Act.  In January 2017, EPA proposed to ban methylene chloride and restrict NMP in paint strippers, but action has stalled under the Trump Administration.  For over a year, the agency made no effort to finalize these actions – even taking steps to delay any progress.

We are what we eat: New paper outlines how the regulatory gaps in the US threaten our health

Sarah Vogel, Ph.D.is Vice-President for Health.

In a new paper published in PLoS Biology today, Maricel Maffini, Tom Neltner and I detail the regulatory gaps in how the US manages chemicals in food. We explore how failures in our current regulatory system put the public’s health at risk as exemplified in the case of perchlorate, a chemical allowed in food and a well-known endocrine disrupting compound. Perchlorate’s ability to disrupt normal functioning of the thyroid means that even low levels of exposure, especially in those with inadequate iodine intake, can adversely impact the developing brains of infants and children. It is not a chemical that should be in the food of pregnant women, infants and children. And yet it is, and the levels children consume have increased in recent years.

A non-estrogenic alternative to Bisphenol A at last?

A non-estrogenic alternative to Bisphenol A at last?

Sarah Vogel, Ph.D.is Vice-President for Health.

Last week a new study was published showing promising results for a non-estrogenic alternative to polymers based on bisphenol A (BPA) used to line the  inside of food cans.  The paper, in Environmental Science & Technology (ES&T), evaluated the estrogenicity of an alternative to BPA— tetramethyl bisphenol F (TMBPF) — and its final polymer product developed by Valspar, a major paint and resin company. The authors found that, unlike BPA and some of its analogs that have been used as substitutes, TMBPF exhibited no signs of estrogenicity.

This was an unusual paper on a number of fronts—how the material was selected, how it was evaluated and by whom.  In this post I’m going to explore who was involved, what testing was done and what this might mean for the BPA alternatives market.

Washington Post looks at the long and painful history of Lead in Drinking Water rule

Sarah Vogel, Ph.D.is Vice-President for Health.

If you missed last week’s Washington Post piece, “The EPA’s lead-in-water rule has been faulted for decades. Will Flint hasten a change?”  we suggest you go back and take a look. Post reporter Brady Dennis takes us back to the beginning to figure out how a federal rule intended to help ensure safe drinking water nationwide faltered, and why it has taken so long to fix.

In 1991, EPA issued the Lead and Copper Rule to reduce lead in drinking water that primarily relied on corrosion control. But initial progress stalled and the rules shortcomings became clear. As EPA Administrator Gina McCarthy explained at a recent hearing, the rule “needs to be strengthened.” Critics claim the outdated rule has become too easy to evade and too hard to enforce.

EPA now is developing an overhaul of the rule. Given the complexity and scope of the challenge, as my colleague Tom Neltner points out, the stakes are high and the agency needs to get it right.

Neltner should know. He served on the expert panel advising the EPA National Drinking Water Advisory Council (NDWAC) which looked at the rule’s flaws. For example, EPA’s original “lead action level” was based on whether or not corrosion control was working and not on the health risk. The group Neltner served on recommended establishing a new health-based “household action level” that will empower people to make informed choices about how to manage their risk to lead hazards in water. In February 2015, EPA agreed to develop an estimated level for the panel to consider. Given the consumer’s need for the number as a result of Flint, EDF has urged that the agency move quickly to release the household action level.

EPA has indicated the lead rule update will be issued in 2017. But with bipartisan Hill support and a new Presidential Administration on the horizon, many are anxious to see it move faster.

No Safe Level: Old pipes and paint threaten the health of America’s children

Sarah Vogel, Ph.D.is Vice-President for Health.

Since the crisis in Flint hit the national headlines, the problem of lead exposure from drinking water has come under greater scrutiny. And for good reason. Seven to ten million American homes have water delivered through service lines made of lead pipe – the primary source of lead in drinking water. But the events in Flint also highlight the fact that despite decades of decline in the levels of lead in the blood of American children, we still have a lead problem in this country. Given that there is no safe level of exposure to lead, we have a lot of work to do. The current crisis offers a new opportunity to make significant progress, and we have a record of past achievement to learn from and build upon.

Forty years ago over 13 million young children in American had blood lead levels at or above 10 micrograms per deciliter (µg/dL). By 2000, that number had decreased to just under a half a million. The greatest reductions made were among low income and children of color who had the highest blood lead levels. As a result of such significant progress, many declared victory and organizations, including EDF, shifted their focus to other environmental health issues leaving considerable work still to be done on lead.

While blood lead levels were declining, scientific evidence was mounting to show there is no safe level of exposure to lead in infants and young children. Studies showed that adverse neurological effects were happening at lower and lower levels of lead exposure. In 2012, the Centers for Disease Control and Prevention reduced the level of lead in blood used to identify those with elevated exposure to 5 µg/dL. Today, approximately 500,000 children have levels at or above 5 µg/dL.

Despite the major declines in children’s blood lead levels at or above 10 µg/dL and decreases in racial and income disparities since the mid-1970s, progress has stalled over the past decade. And still disparities persist. Children living in poverty remain at the greatest risk. Indeed, children in poor households are three times more likely, and African-American children are twice as likely as white children, to have elevated blood lead levels. Read More »

New bill puts BPA back in the spotlight

Sarah Vogel, Ph.D., is Director of EDF's Health Program.

The hotly debated chemical BPA is back in the policy spotlight. This week Senator Edward Markey (D-Mass) joined Representatives Lois Capps (D-CA) and Grace Meng (D-NY) to announce the Ban Poisonous Additives (BPA) Act.  The bill would ban the use of BPA or bisphenol A from food packaging and mandates extensive consideration of the hazardous properties of any BPA alternative, so as to avoid substituting chemicals that may pose just as many health risks (as increasingly it appears to be with the case of the common BPA replacement, BPS).

Low dose exposure to BPA has been associated with a wide range of health effects including behavioral problems, prostate, breast and liver cancer as well as obesity.  A study released just last week demonstrated how low dose exposure to BPA during fetal development can alter gene expression in the mammary gland of female rats, resulting in abnormal development of the breast and increased susceptibility to breast cancer later in life.   Read More »
