Chemical safety evaluation: Limitations of emerging test methods

Jennifer McPartland, Ph.D., is a Health Scientist. Richard Denison, Ph.D., is a Senior Scientist.

Parts in this series:      Part 1     Part 2     Part 3     Part 4

This is the fourth in a series of blog posts on new approaches that federal agencies are exploring to improve how chemicals are evaluated for safety.  In this post, we’ll discuss a number of current limitations and challenges that must be overcome if the new approaches are to fulfill their promise of transforming the current chemical safety testing paradigm.  Read More »

ACC resorts to smear tactics to defend its cash cows, formaldehyde and styrene

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

An increasingly common tactic in modern bare-knuckle politics is to divert attention away from your own weakness or vulnerability by loudly – and falsely – accusing your opponent of having that very defect you possess but won’t admit to.

That Rovian tactic was on display last week, with the American Chemistry Council (ACC) as the accuser, and the National Toxicology Program (NTP) as its “opponent.”  Mind you, NTP is the nation’s leading authoritative body on cancer-causing chemicals.

The precipitating event?  NTP’s long-overdue release of its 12th Report on Carcinogens (RoC).  Among other additions NTP made since its last report was published way back in 2005, it had the audacity – according to ACC – to:

  • upgrade its classification of formaldehyde to “Known to be a human carcinogen,” from its earlier classification (dating back to 1981) as “Reasonably anticipated to be a human carcinogen,” and
  • for the first time include styrene on its list of chemicals linked to cancer, classifying it as “reasonably anticipated to be a human carcinogen.”

The accusation hurled at NTP was this gem from ACC President and CEO, Cal Dooley:

“We are extremely concerned that politics may have hijacked the scientific process and believe this report by HHS is an egregious contradiction to what the President said early in his administration, ‘…That science and the scientific process must inform and guide decisions of my administration…’.”

Talk about the pot calling the kettle black (per the “second, subtler interpretation” of that phrase).

ECHA adds seven more Substances of Very High Concern to REACH Candidate List

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

The European Chemicals Agency (ECHA) issued a press release on Tuesday announcing the addition of seven chemicals to the Candidate List of Substances of Very High Concern (SVHC) under the European Union’s REACH Regulation.  [Update 6/20/11:  The formal addition of these substances to the candidate list, the initial announcement of which this post addressed, happened today.  See ECHA’s press release, which also contains some additional information about the uses of these chemicals.  The full candidate list including these seven substances is available here.]

All of the chemicals are officially classified as Carcinogenic, Mutagenic or Reproductive toxicants (CMRs).  Their addition brings the total number of chemicals on the Candidate List to 53.  Adding a chemical to REACH’s Candidate List is the first step toward subjecting it to REACH’s Authorization process, whereby the chemical can be used only if specifically authorized by EU authorities.

In this brief post we present a bit more information on these latest seven SVHCs, including the extent of their presence in U.S. commerce and their main uses.  Read More »

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

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 »

Chemical safety evaluation: Potential benefits of emerging test methods

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

Parts in this series:      Part 1     Part 2     Part 3     Part 4

This is the third in a series of blog posts on new approaches that federal agencies are exploring to improve how chemicals are evaluated for safety.  Previous posts primarily focused on the scientific principles underlying these efforts.  This post will take a pause from scientific fundamentals to discuss some of the opportunities presented by these more novel methods, while subsequent posts will address some of their limitations and remaining challenges.  (Not to worry, though, I’ll soon get back to computer-simulated organs as promised.)  Read More »

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

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:
