Exposure to toxic flame retardants is an environmental justice issue: New research finds differential exposure in children

By Richard Denison / Published: May 23, 2012

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

A peer-reviewed paper released today documents that nonwhite toddlers in North Carolina carry nearly twice as much of certain toxic flame retardant chemicals in their blood compared with white toddlers.  The finding adds to a growing body of evidence that exposures to toxic chemicals are higher in communities of lower socioeconomic status.

Numerous other studies have found higher levels of the flame retardants known as polybrominated diphenyl ethers, or PBDEs, in children and adolescents relative to adults.  The current study – authored by Stapleton et al., and appearing in Environmental Health Perspectives – may be the first, however, to demonstrate differential exposure based on socioeconomic status.

Estimating chemical risk: Breadth (prevalence) may be just as important as depth (magnitude of effect)

By Jennifer McPartland / Published: April 23, 2012

Jennifer McPartland, Ph.D., is a Health Scientist.

Earlier this month Dr. David Bellinger at Boston Children’s Hospital published a very interesting paper in Environmental Health Perspectives offering a new way to consider the importance of various risk factors for child neurodevelopment—such as pre-existing medical conditions, poor nutritional status or harmful chemical exposures—at the population level.  “A Strategy for Comparing the Contributions of Environmental Chemicals and Other Risk Factors to Neurodevelopment of Children” argues that, in evaluating the contribution of a risk factor to a health outcome, it is critical to consider not only the magnitude of its effect on the health outcome, but also the prevalence of that risk factor in the population.

Dr. Bellinger argues: “Although a factor associated with a large impact would be a significant burden to a patient, it might not be a major contributor to the population if it occurs rarely.  Conversely, a factor associated with a modest but frequently occurring impact could contribute significantly to population burden.”  The former “disease-oriented” approach has generally been used to estimate the burden of harmful chemical exposures to population health, rather than the latter “population-oriented” approach.  Relying solely on the former approach, he contends, may result in an underestimation of the impact of a chemical exposure or other risk factor on public health.  Read More »

They paved paradise, all right, and with a potent human carcinogen to boot

By Richard Denison / Published: May 17, 2011

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

Imagine if someone spread a human carcinogen across millions of acres of land.  Then imagine that the carcinogen was found to be entering surface waters due to runoff from the treated acreage.  And then that the carcinogen was found to be accumulating in the dust in homes located near the treated acres.

Far-fetched?  Hardly.  Welcome to the good ol’ US of A.   Read More »

A most-pressing Health Affair: Acting as if our children’s health matters

By Richard Denison / Published: May 5, 2011

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

Health policy history of sorts was made this week:  The prestigious journal Health Affairs, the nation’s leading journal of health policy, unveiled its first-ever issue devoted entirely to environmental health.  It did so via a briefing held in Washington, DC on Wednesday that featured several pre-eminent environmental health experts, including David Fukuzawa, Program Director for Health at The Kresge Foundation; Linda Birnbaum, Director of the National Institute of Environmental Health Sciences (NIEHS); and Kenneth Olden, Professor and Founding Dean at the new City University of New York’s School of Public Health and former long-time NIEHS Director.

A sneak peak has been provided via advanced publication of some of the journal issue’s articles.  Prominent among the themes of these articles:  The high and increasing health and economic costs of unregulated exposures to unsafe and inadequately tested chemicals.

I’ll call attention here to two papers in particular:

Pediatricians: Reform TSCA to protect kids. ACC responds (a la W.C. Fields): We love kids, too

By Richard Denison / Published: April 26, 2011

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

A long-awaited and full-throated endorsement of comprehensive reform of the Toxic Substances Control Act (TSCA) from the venerable American Academy of Pediatricians (AAP) was published online yesterday in the journal Pediatrics.

Right down the line, the AAP’s 8-page policy statement calling for a wholesale overhaul of TSCA mirrors the recommendations of health and environmental advocates, academic researchers and just about anyone else who has paid attention to the mounting body of evidence documenting the linkages between rising chemical exposures and adverse effects on the health of our population, especially the most vulnerable among us:  the developing fetus, infants and young children.

The AAP’s recommendations also closely track key provisions in TSCA reform bills introduced last year in both Houses of Congress as well as the Safe Chemicals Act of 2011 just re-introduced in the U.S. Senate this month.

This latest statement from the Academy adds it to the list of other major medical and health associations that have previously called on Congress to  revamp TSCA, including the American Medical Association, the American Public Health Association and the American Nurses Association.

Given this growing chorus, it is perhaps not surprising that the American Chemistry Council (ACC) would seek to worm its way in to claim that it, too, loves kids and supports TSCA reform.

But dig a bit deeper, and what is most striking is that ACC stridently opposes essentially every element of TSCA reform called for by the American Academy of Pediatrics.  Read More »

Memo to ACC et al.: What’s said in Maryland doesn’t stay in Maryland

By Richard Denison / Published: March 10, 2011

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

It’s only a little more than 30 miles from Washington, DC to Annapolis, the Capitol of the State of Maryland.  But to judge from testimony given there on February 24 and March 1 by representatives of the chemical, formulated products and food industries, you’d think Annapolis existed in a parallel universe, with only a passing resemblance to the one in DC.

The occasions were hearings on companion bills introduced into the Maryland State Senate, SB 637, and the State House of Delegates, HB 759, titled the “Healthy Kids, Healthy Maryland – Toxic Chemical Identification and Reduction.”

Actually, the industry associations’ testimonies suggest either of two alternative universes.  In one of them, Maryland should do nothing to address dangerous chemical exposures because the federal Toxic Substances Control Act (TSCA) and other related laws are working quite well, thank you very much.  Residing in this parallel universe are the American Chemistry Council (ACC), the American Cleaning Institute (ACI, until recently the more accurately named Soap and Detergent Association), the Maryland Industrial Technology Alliance and the Consumer Specialty Products Association (CSPA).

In the other parallel universe, Maryland should do nothing to address dangerous chemical exposures because it will only get in the way of TSCA reform, which is just around the corner.  Inhabiting this alternative universe are the Grocery Manufacturers Association (GMA), the Can Manufacturers Institute, and yes – as another indication that it just can’t quite make up its mind about TSCA reform – once again, the American Chemistry Council.  Read More »
