Protecting ourselves from harmful chemical exposures: Your chance for input

National Conversation on Public Health and Chemical Exposures

http://www.atsdr.cdc.gov/nationalconversation/

Project goals – http://www.atsdr.cdc.gov/nationalconversation/accomplish.html

The National Conversation’s vision is to ensure that chemicals are used and managed in safe and healthy ways for all people.  The goal of the National Conversation is to develop an action agenda—clear, achievable recommendations—that will help government agencies and other organizations strengthen their efforts to protect the public from harmful chemical exposures.  The action agenda will help our nation identify better ways to

  • Collect information about chemical use, people who are exposed, and the levels at which they are exposed.
  • Understand how chemicals affect people’s health.
  • Use policies and practices that tell us about risks, how to reduce harmful exposures, and how to create and use safe chemicals.
  • Prevent, prepare for, and respond to chemical-related emergencies.
  • Protect all communities from harmful chemical exposures.
  • Create a well-informed public and health care provider network to help people understand chemical exposure risks.
  • Involve the public in government decision making.
  • Encourage teamwork among partner groups and agencies.

To help with this, work groups were formed last year to discuss six cross-cutting issues.  After receiving public input, they have released draft reports for public comment.  You can download the report for each work group from the pages linked to below and submit your comments via those pages, e-mail or other means listed there.

CDC and ATSDR are working with RESOLVE, a non-profit facilitation group that will compile the comments, as well as other organizations such as the American Public Health Association, Association of State and Territorial Health Officials, and National Association of County and City Health Officials.

Back in the real world: Human exposure to environmental chemicals

Another type of exposure besides exposure to 24/7 connectedness that is probably affecting kids is exposure to industrial chemicals.  The Centers for Disease Control and Prevention (CDC) recently released its fourth National Report on Human Exposure to Environmental Chemicals. (Fact Sheet / Executive Summary – 874 KB / Full report – 18 MB)

CDC has measured 212 chemicals in people’s blood or urine—75 of which have never before been measured in the U.S. population. The new chemicals include acrylamide, arsenic, environmental phenols, including bisphenol A (BPA) and triclosan, and perchlorate.  BPA was found in the urine of nearly all the people tested, a finding that indicates widespread exposure in the U.S. population.  Mercury, a known neurotoxin, was found in most of the study participants.

CDC notes:

Biomonitoring measurements are the most health-relevant assessments of exposure because they measure the amount of the chemical that actually gets into people from all environmental sources (e.g., air, soil, water, dust, or food) combined. With a few exceptions, it is the concentration of the chemical in people that provides the best exposure information to evaluate the potential for adverse health effects.

This is not a new issue.  Several years ago the Environmental Working Group released a report, Body Burden: The Pollution in Newborns, which measured industrial chemicals, pollutants, and pesticides in the umbilical cord blood of newborns.

287 chemicals were detected in umbilical cord blood, of which 180 cause cancer in humans or animals, 217 are toxic to the brain and nervous system, and 208 cause birth defects or abnormal development in animal tests.  The report notes that a number of human health problems are on the rise.  Fetal and childhood exposure can lead to childhood diseases or to diseases which don’t fully appear until adulthood.

So what can be done about this?

EWG has a blog on the Kid-Safe Chemical Act and the Environmental Defense Fund‘s Richard Denison has a blog on chemicals and nanomaterials.   EDF is also one of many organizations that has formed the “Safer Chemicals, Healthy Families” coalition, which is pushing for reforming the way the manufacture of industrial chemicals is regulated in the United States.  One of the U.S. Environmental Protection Agency’s main tools for doing that is a relatively unknown law called the Toxic Substances Control Act (TSCA).  The Safer Chemicals coalition presents a health case for strengthening TSCA.  (TSCA has actually been in the news quite a bit lately, so you might have heard about it.)
