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.)

  2. very interesting.. thank you. I am on a mission of informing the average joe to think twice before tossing that burned out bulb into the kitchen garbage can. Let’s keep disgarded CFL bulbs out of the landfills…do you think it’s a worthy cause? Why don’t we hear more about recycling these bulbs from the same entities who pushed them as a way to save energy and reduce our carbon footprint?
