I blogged earlier about EDF’s strong concerns with Michael Dourson’s nomination to head the EPA office charged with implementing the Toxic Substances Control Act (TSCA).  Among these concerns are his extensive, longstanding financial ties to the chemical industry – an industry that, if he is confirmed, he will be in charge of regulating.  And not only does Dourson have these financial ties to the industry, he has made a career of helping industry play down concerns about chemicals.

A case in point is described in an article published just last week in The Intercept about his work in the early 2000s in West Virginia on behalf of DuPont and its still ongoing woes over water contamination involving the “Teflon” chemical PFOA.

Dourson’s paid work for industry goes back over two decades, starting just after he left EPA in 1994, and it includes work he did for the tobacco industry in the late 1990s and early 2000s.  As I noted in my last post, his work for the chemical industry included developing a website, “kidschemicalsafety.org” (now defunct, but archived here), that consistently downplayed concerns about chemicals.

To illustrate the extent of his more recent conflicts, we examined the funding sources, where disclosed, for the several dozen papers he authored or co-authored that are listed in PubMed as published between 2005 and 2017.  Some of what we found is reported in this post; there will be more to come on the substance of these papers.   Read More »

EDF has deep concerns over nomination of industry consultant to lead toxics program at EPA

We are deeply concerned over the nomination of Michael Dourson to head the toxics office at EPA.  Unfortunately, this nomination fits the clear pattern of the Trump Administration in appointing individuals to positions for which they have significant conflicts of interest.  Dr. Dourson has extensive, longstanding ties to the chemical industry (as well as earlier ties to the tobacco industry).  He also has a history of failing to appropriately address his conflicts of interest.  For example:   Read More »

Conflicted West Virginia chemical spill panel is repeating many of CDC’s mistakes

Yesterday, the chair of a “Health Effects Expert Panel” convened by the West Virginia Testing Assessment Project (WV TAP) held a press conference to present the panel’s preliminary findings from its review of the “safe” level set by the Centers for Disease Control (CDC) for MCHM and other chemicals that spilled into the Elk River in early January and contaminated the drinking water of 300,000 West Virginia residents.

A final report from the panel apparently won’t be released until May, but a press release issued yesterday sounds far from preliminary in saying the panel supports CDC’s methods, assumptions, toxicity data and “safety factors.”  While providing no details, the release indicates the panel is using the same flawed and incomplete summary of a toxicity study used by CDC in its rush to set a safe level for MCHM.  And it parrots CDC’s erroneous use of the term “safety factors,” which is at odds with the National Academy of Sciences’ strong recommendation that such term should be avoided as it is highly misleading.

In addition to choosing to rely on the same summary CDC used of a 1990 study conducted by MCHM’s manufacturer, Eastman Chemical, the panel accepted at face value Eastman’s interpretation that the study identified a no-effect level.  That conclusion has been questioned and cannot be independently assessed because Eastman has not provided the actual quantitative data from the study.  Moreover, the study used a protocol dating from 1981 that has been extensively revised at least twice since then.  These are among the many problems identified with this study.

It appears the panel’s main departure from CDC was to assume the most highly exposed population would have been formula-fed infants instead of older children.  The panel’s “safe” level is 120 parts per billion (ppb), a value about 8-fold lower than CDC’s level of 1 part per million (ppm).  That seems an improvement over the CDC’s methodology.

The panel’s conflict of interest

However, the process by which the panel itself was formed and the clear conflict of interest (COI) involved – a conflict that only came to light in response to a reporter’s questions at yesterday’s press conference – are deeply concerning.   Read More »

TERA’s Kids+Chemical Safety website: On non-profits, objectivity and independence

By / Published: December 21, 2012

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

My recent post about the new American Chemistry Council (ACC)-sponsored website, Kids + Chemical Safety, engendered some comments that go directly to the issues of scientific objectivity and independence.

The website says “TERA [Toxicology Excellence for Risk Assessment, manager of the site] was founded on the belief that an independent non-profit organization can provide a unique function to protect human health by conducting scientific research and development on risk issues in a transparent and collaborative fashion and communicating the results widely.”  The “non-profit” descriptor – which TERA uses to describe itself no fewer than eight times on the site, including four times on this one page alone – seems intended to convey that TERA provides information that is purely objective and that it operates in a manner that is independent of who pays it to do its work.

It’s critical to recognize that being a non-profit does not conflate to, or somehow confer the right to claim, objectivity or independence.  The National Rifle Association is a non-profit that clearly has strongly held and expressed opinions.  EDF is also a non-profit, but I don’t pretend, as does TERA, that we don’t have a particular perspective and position.

So putting the issue of non-profit status entirely aside, we should judge TERA’s claim that its website provides information that is objective and independent based on its content, and that’s where it becomes quite clear that the information is neither.  Read More »

Chemicals R Us: New ACC-sponsored website says chemicals are safe and fun for kids!

By / Published: December 19, 2012

[See also my more recent post on this topic here.]

I was alerted yesterday to a new website – kidschemicalsafety.org – funded by the American Chemistry Council (ACC) and run by its right-hand “non-profit,” TERA (Toxicology Excellence for Risk Assessment).  The website and an accompanying Facebook page are a wonder to behold, replete with photos of happy kids.  For the most part, I’ll leave it to you to explore.  But here are a few highlights.  Read More »
