More “A”-level work under REACH: ECHA adds eight chemicals to the Authorization List

By Allison Tracy / Published: February 15, 2012

Allison Tracy is a Chemicals Policy Fellow.

The European Commission has formally added eight more chemicals to the list of chemicals subject to authorization under the European Union’s Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH).  These eight chemicals, which were proposed for addition to the Authorization List (or Annex XIV) in December 2010, join the six inaugural chemicals that were formally listed last February (see EDF’s blog post on that occasion).  The full Authorization List is available on ECHA’s website; the list also specifies the corresponding sunset date by which time uses of a chemical must cease unless specifically authorized.

Linking everyday chemicals to disease: New science keeps on intensifying the writing on the wall

By / Published: February 10, 2012

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

As a Washington policy geek, it’s sometimes hard not to let the ups and downs of political prospects for achieving real improvements in public health protections from toxic chemicals get me down.  The tenacity with which some stakeholders insist on throwing wrenches into the works to block efforts to reach middle ground is indeed depressing.

But through it all, there is one constant that continually restores my optimism that we’ll eventually get where we need to get to:  Science keeps moving forward and inexorably points toward the need for reform.  I will use this post to briefly highlight four recent studies that demonstrate the changing landscape of our knowledge of how environmental factors, including toxic chemical exposures, are affecting our health.  What’s noteworthy about these studies is that they all identified adverse health effects in human populations, and linked those effects to early-life exposures.  They all also illustrate the complex interplay between chemical exposures and social or other environmental factors that directly challenges the overly simplistic and non-scientific approach to causation that our chemicals policies have taken for decades.

Below are summaries of and links to these new studies:

  • Early-life exposure to PCE is associated with later-life risky behaviors.
  • Phthalate exposure is associated with excess weight in New York City children.
  • Exposure to perfluorinated chemicals may interfere with childhood vaccine effectiveness.
  • Epigenetic changes are associated with socio-economic status and biomarkers for cardiovascular disease.

No orphan left behind: Health and environmental NGOs support EPA’s proposed paired rules to address high production volume “orphan” chemicals

By / Published: January 18, 2012

Richard Denison, Ph.D., is a Senior Scientist.  Allison Tracy is a Chemicals Policy Fellow.

Environmental Defense Fund today submitted comments along with 15 other health, environmental justice and state and national environmental organizations, in support of EPA’s proposed rule to address the final batch of 45 “orphan” chemicals that were never sponsored under the agency’s earlier High Production Volume (HPV) Challenge Program.

An earlier post to this blog highlighted and applauded the novel, innovative and efficient approach EPA has proposed, which actually entails the coupling of two rules:

(1) a test rule for 23 of these HPV chemicals for which EPA can make the requisite exposure findings to require testing, combined with:

(2) a Significant New Use Rule (SNUR) for the other 22 HPV chemicals for which EPA cannot presently make such findings, which requires companies to notify EPA if their production or use of those chemicals changes so as to increase the potential for exposure and then warrant testing.

The comments we filed today reiterate our strong support for this approach – and propose that the same approach be extended to several additional batches of HPV chemicals that still lack a basic set of hazard data.

REACH starts to earn its “A”: 20 chemicals headed to the Candidate List and 13 to Authorization

By Allison Tracy / Published: December 21, 2011

Allison Tracy is a Chemicals Policy Fellow. Richard Denison, Ph.D., is a Senior Scientist.

The European Chemicals Agency (ECHA) has been busy this week implementing the EU’s chemical regulation, REACH (short for Registration, Evaluation, Authorization and Restriction of Chemicals).

On Monday, ECHA announced it has added 20 more Substances of Very High Concern (SVHCs) to REACH’s Candidate List.  These SVHCs are now eligible for later addition to Annex XIV, the list of SVHCs subject to Authorization.

Separately, the agency today forwarded its final recommendation that 13 chemicals already on the Candidate List be formally added to Annex XIV.  (We had blogged earlier about ECHA’s initial recommendation proposing these 13 SVHCs for Authorization.)  If the European Commission confirms this addition, after a specified sunset date, the use of these will be allowed only if specifically authorized by EU authorities.  Read More »

A new power couple: The combined impact of the microbiome and chemical exposures on disease susceptibility (Part 2 of 2)

By Allison Tracy / Published: December 19, 2011

Allison Tracy is a Chemicals Policy Fellow. EDF Health Scientist Dr. Jennifer McPartland and Senior Scientist Dr. Richard Denison contributed to this post.

In Part 1 of this two-part post, I reviewed scientific evidence that the gut microbiome interacts with ingested chemicals to influence susceptibility to obesity and diabetes.  This hypothesis is the focus of a recent review article by Suzanne Snedeker and Anthony Hay.  Having reviewed evidence of the link between the microbiome and obesity and diabetes as well as the link between chemical exposures and obesity and diabetes, we now proceed to address this question:  Can the gut microbiome act in concert with ingested synthetic chemicals to predispose people to obesity and diabetes?

A new power couple: The combined impact of the microbiome and chemical exposures on disease susceptibility (Part 1 of 2)

When you’re standing at the kitchen counter this holiday season wrestling with the nebulous world of weight gain, think about synthetic chemicals.  A good number of them are in you.  And studies show that some of them are pretty busy in there, interacting with various biological systems – including your metabolism.

But they’re not the only show in town.  Microbes are busy in your gut doing important things like digesting food and degrading harmful compounds.  But could they also influence the size of your love handles?  New science suggests that these microbes—in concert with certain chemicals—may have just this effect.

It is becoming increasingly clear that it’s not just your genes and your self control that determine your risk for obesity and related complications like diabetes.  Environmental factors are a big part of the equation, and those factors just might extend to synthetic chemicals to which you’re exposed, such as the flame retardants in your furniture and the plasticizers in food can linings.  Read More »
