The States we’re in on chemical policy reform in 2011: 30 and counting

By / Published: January 19, 2011

Richard Denison, Ph.D., is a Senior Scientist.

Today, legislators in 30 states and the District of Columbia introduced or announced plans to introduce bills aimed at reducing the impact of chemicals on public health.  These actions send a strong signal that states will to continue to respond to the mounting public concern over unsafe, under-regulated and inadequately tested chemicals — in the face of continued inaction by the U.S. Congress to do so.

The bills differ in scope and content, but all of them address chemicals, products or policy needs that have fallen through the cracks in the 35 years since the Toxic Substances Control Act (TSCA) was enacted.

With strong, bipartisan majorities of Americans embracing the need for stronger chemical laws, these latest actions make clear that states will continue to act until there is a strong federal system in place that restores confidence in our government’s ability to assure the safety of all chemicals we use and encounter in our daily lives.  Read More »

Do these chemicals make me look fat?

By EDF Blogs / Published: January 19, 2011

Woman in mirrorJennifer McPartland, Ph.D., is a Health Scientist.

My colleague Richard Denison at EDF ended his last blog post asking, “The new study [Environmental Chemicals in Pregnant Women in the US: NHANES 2003-2004] leaves me with one question:  How many more such wake-up calls do we need before our government enacts policies to ensure the safety of chemicals to which we are exposed?”

Maybe this will help shake us awake!  The obesity epidemic in the United States is increasing at alarming rates.   So too is an associated disease, type 2 diabetes.  Researchers have attributed 70% of the risk associated with developing type 2 diabetes with being overweight or obese, a risk that increases by 4.5% for every 2.2 pounds of weight gained over 10 years.

A healthy diet and hitting the gym should keep these diseases at bay, right?  Certainly proper nutrition and exercise are good and important habits for controlling our weight and maintaining overall health.  But what if, despite all such efforts, there are contributing factors outside of our control, and even outside of our genetic makeup?  And what if those potential factors are found in us, on us, and all around us?

New research suggests that chemicals found in our environment and in everyday products may play a significant role in packing on the pounds.  Read More »

Why is OMB blocking EPA from using even its limited authority under TSCA?

By / Published: December 20, 2010

Richard Denison, Ph.D., is a Senior Scientist.

On May 12 of this year, the Environmental Protection Agency (EPA) sent a proposed rule to the Office of Management and Budget’s (OMB’s) Office of Information and Regulatory Affairs (OIRA) for its review, which is supposed to be completed within 90 days.  The proposed rule is not considered a major rule, is classified as “not economically significant,” imposes no unfunded mandates and is unequivocally allowed under EPA’s statutory authority under the Toxic Substances Control Act (TSCA).

The proposed rule would establish a so-called “chemicals of concern” list and populate it with one chemical and two chemical categories.  All of these chemicals are well-studied, already widely identified to be chemicals of significant concern and subject to numerous regulations by governmental bodies both in the U.S. and abroad.

Yet, as of today – more than seven months after receiving the draft of the proposed rule from EPA – OMB has not allowed EPA to release it for public notice and comment.

In 1976, when passing TSCA, Congress gave EPA the express authority to establish and populate a “chemicals of concern” list.  There’s simply no excuse for OMB’s delay.  Read More »

Hitting ’em where it hurts: BPA reduces sperm quantity and quality in male workers

By / Published: October 28, 2010

Richard Denison, Ph.D., is a Senior Scientist.

As reported by Rob Stein in the Washington Post this morning, a NIOSH-funded study of male Chinese workers conducted by researchers at Kaiser-Permanente in Oakland, California has found that exposure to the endocrine-disrupting chemical bisphenol A (BPA) significantly increases the incidence of low sperm counts and concentrations, as well as lowered sperm motility and higher mortality.

The 5-year study, published in the peer-reviewed journal Fertility and Sterility (that’s a title only slightly more cheery than the CDC’s publication Morbidity and Mortality!), shows that the same kinds of adverse effects of BPA on sperm already observed in animal studies also occur in humans with detectable levels of BPA in their urine.

And while the most pronounced effects were observed in highly exposed workers, the authors of the study note:

Similar dose-response associations were observed among participants with only environmental BPA exposure at levels comparable to men in the general United States population.

Despite a markedly reduced sample size in this group of men exposed only to low environmental BPA sources, the inverse correlation between increased urine BPA level and decreased sperm concentration and total sperm count remain statistically significant.

The Katrina chronicles: Formaldehyde-laced trailers set to claim another set of victims

By / Published: March 14, 2010

Richard Denison, Ph.D., is a Senior Scientist.

The Washington Post ran a front-page article Saturday, written by Spencer Hsu, which reported the auction sale by FEMA of most of the 120,000 notorious formaldehyde-tainted trailers it had purchased five years ago to house the victims of Hurricane Katrina.

The article cites FEMA as saying that “wholesale buyers from the auction must sign contracts attesting that trailers will not be used, sold or advertised as housing, and that trailers will carry a sticker saying, ‘Not to be used for housing’.”

Think that’s likely to be enough?  Read More »

Immaculate deception, part 2: Chemical industry front group calls for ban on bisphenol A

By / Published: December 15, 2009

Richard Denison, Ph.D., is a Senior Scientist.

I’ll bet that got your attention.  Surely I jest, you’re thinking.  Well, on December 2, Montana Public Radio’s Evening Edition included a segment in which a spokesperson for the new chemical industry front group, the Coalition for Chemical Safety about which I blogged a few weeks ago, publicly calls for an all-out ban on the controversial endocrine-disrupting chemical bisphenol A (BPA).  Here’s the clip (5 MB mp3 file).
