No shame: ACC plunges to new low in fighting your right to know

By / Published: May 21, 2012

This post is longer than usual and starts with a rather esoteric topic, but I urge you to read it through, as it vividly shows there is no limit to the lengths to which the American Chemistry Council (ACC) will go to squirm out of a regulatory requirement, even if it means violating rules by which ACC had agreed to abide.

But that’s far from the worst of it.  Going farther than even I could imagine when I blogged earlier about its tactics, ACC is sparing no effort to deny your right to know about the health impacts of chemicals, by mustering every argument it can invent – however far-fetched – to  keep health and safety studies from being shared with the public.

ACC insists that the U.S. Environmental Protection Agency (EPA) should hassle the European Union (EU) instead of its members for the health and safety data ACC promised to provide – despite the fact that the chemical industry itself has thrown up major roadblocks to such sharing.  And reaching a new low in tortured logic, ACC argues that, should EPA succeed in getting its hands on the health and safety data submitted to the EU, EPA can and should deny the public access to those data – despite the fact that the Toxic Substances Control Act (TSCA) clearly prohibits EPA from withholding such information.  Read More »

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 »

Striking the right balance between right to know and right to intellectual property protection

By / Published: April 13, 2012

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

There is clearly a need to balance the legitimate claims of companies to protect certain confidential business information (CBI) from public disclosure with the legitimate need for the market, consumers and the public to have access to information they need to make sound decisions about chemicals that are in commerce.  Unfortunately, most of TSCA’s provisions and their implementation by EPA have skewed this balance radically in the direction of denying the public’s right to know and creating an ill-informed chemicals marketplace.

The core problem is two-fold, constituting a vicious circle:  Too many CBI claims are made, and each of the infrequent examinations of such claims done by EPA has found a large fraction to be illegitimate, i.e., not meeting the well-established criteria for what constitutes a legitimate trade secret.  And because of the large number of claims made, EPA has lost the ability to review claims to ensure they are in fact legitimate and remain so over time; this lack of review has led directly to more claims being made, thereby completing the vicious circle.  Read More »

Restoring the credibility of risk assessment: A vital need under TSCA reform

By / Published: April 6, 2012

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

The primary means by which chemical risks are to be judged under current legislative proposals for reform of the Toxic Substances Control Act (TSCA), including the Safe Chemicals Act of 2011 (S. 847), is through risk assessment – a key demand of industry.  Yet traditional risk assessments have often fallen short of protecting public health and have sometimes taken decades to identify a “safe” level of exposure to certain chemicals.  As a result, public and health and environmental community confidence in risk assessment is very low.  There are also major technical deficiencies in current risk assessment methodologies that must be addressed if it is to serve as a credible basis for determining chemical risks.  For example, we now know that there are many chemicals for which any level of exposure poses some risk, yet traditional risk assessment assumes a safe level exists for nearly all chemicals.

The Safe Chemicals Act includes provisions to ensure that EPA’s use of risk assessment incorporates the best available science, initially by requiring EPA to rely on the recent recommendations of the nation’s foremost scientific body, the National Academy of Sciences, as to how EPA can improve its practice of risk assessment. Implementing the recommendations is critical to restoring the credibility of and public confidence in risk assessment. Read More »

Exposing our ignorance: EPA study reveals barren exposure data landscape

By Jennifer McPartland / Published: March 16, 2012

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

This past November, EPA scientists published a sobering paper, “The exposure data landscape for manufactured chemicals,” in the journal Science of the Total Environment.  The paper reveals how little systematic information we have about human and environmental exposures to the thousands of chemicals in use today.

The aim of the study was “to define important aspects of the [chemical] exposure space and to catalog the available exposure information for chemicals being considered for analysis as part of the U.S. EPA ToxCast screening and prioritization program.”  Its conclusion:  “The results suggest that currently available exposure data are insufficient to provide the evidence base required to inform risk assessment and public health decision making.”  Not good, but not surprising.  Read on for more detail.

Smoke and Mirrors: ACC lawyers are working hard to rein in your right to know

By / Published: March 1, 2012

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

I’ve blogged here frequently about EPA’s efforts over the past couple of years to make more chemical information available to the public, especially health and safety information.  A key part of this, believe it or not, is simply making sure that when EPA shares a health study with the public – as required by law – you get to know the identity of the chemical that is the subject of that study.

EPA’s initial steps (see below) were met with a little grumbling on the part of the chemical industry, but not a whole lot.  After all, the industry says it wants the public to have more information about chemicals.  At #7 on the American Chemistry Council’s (ACC) top 10 principles for TSCA reform is:  “Companies and EPA should work together to enhance public access to chemical health and safety information.”

Times, apparently, have changed.  In recent weeks, ACC has launched a broadside attack on the EPA’s efforts to compel its member companies ever to name a chemical when submitting health and safety information to EPA.  My evidence?  A 36-page White Paper delivered by ACC to the office of the regulatory czar at the Office of Management and Budget, at a meeting held there on January 20.  The ACC document is a wonder of tortured logic, obfuscation and selective renditions of the history of TSCA.

Today, a response was mounted.  EDF and Earthjustice staff, as well as representatives of health-affected individuals, environmental justice communities and workers, held their own meeting with OMB officials.  And we delivered our own letter to OMB that thoroughly rebuts ACC’s White Paper.  It also points out that, way back in 1976, the drafters of TSCA actually wanted you to have access to health and safety information on chemicals – and they darn well didn’t expect you to have to guess at the identity of those chemicals.  Read More »
