[Repost] Getting Real About Chemical Risks

 

From the 14 October Cover Story at Chemical and Engineering News

Many people assume that the chemicals in their detergents, floor cleaners, and other household products have undergone rigorous safety testing. But little is known about the potential risks associated with most of the estimated 80,000 chemicals in commerce today.

While industry tries to dispel links to illnesses that go beyond what science can prove, the public is skeptical because companies have a financial stake in showing their products are safe. This leads both sides to look to the federal government for help.

The agency charged with overseeing the safety of chemicals in the marketplace is the Environmental Protection Agency. EPA has the authority to require industry to provide extensive toxicity data for pesticides. But for most other chemicals, EPA must show that a substance is likely to be a risk to human health or the environment in order to require industry to provide safety data. Manufacturers don’t often give toxicity data to EPA voluntarily, nor does the agency have the resources to assess tens of thousands of chemicals using traditional in vivo rodent-based studies.

Instead, EPA has turned to computational modeling. One ambitious effort, called ToxCast, aims to screen thousands of chemicals for biological activity using about 600 high-throughput biochemical and cell-based assays. The data are then integrated with existing in vivo animal toxicity data and structure-activity information to predict toxicity.

But ToxCast has had problems. Most of the assays were developed for drug discovery, not to assess the hazards of chemicals in the environment. For example, thyroid-disrupting compounds in the environment can work through multiple pathways, but commercial tests focus on just one—a chemical binding to the thyroid receptor. If a chemical acts on a different pathway it will test negative, even though it does disrupt the thyroid.

How to Handle Mold/Mycotoxin Exposure at Home or at Work – Where To Get Help

I usually don’t reblog articles that endorse commercial products or alternative/complementary medicine (without biomedical evidence).
Still, this post had a lot of good information on testing and one’s rights.

A few years back at a library where I worked, some of the folks at circulation were having breathing difficulties. They believed it was the HVAC system, but did not report it. Now I wish I could have worked with them to report it….
The folks at the circ desk were union, I was not. So they were more protected than I…..
