For decades, it was the secret behind the magic show of homemaking across the US. Applied to a pan, it could keep a fried egg from sticking to the surface. Perfluorooctanoic acid, or PFOA, was ... seeping into the blood and organs of hundreds of millions of people who used products containing the chemical. PFOA is just one of dozens of modern-day chemicals that are found in the bodies of the majority of Americans. Research has also shown that more Americans are facing a growing number of ailments and disorders, from autoimmune disease to developmental disorders such as autism and some cancers. Scientists are increasingly concerned these two truths are linked. Scientists have accumulated enough data to conclude with confidence that humans face significant health risks from exposure to common commercial chemicals, and that regulations designed to protect them are failing. Due to flaws in federal regulation, the US Environmental Protection Agency (EPA) is perennially playing catch up. The majority of the 86,000 consumer chemicals registered with the agency have never received vigorous toxicity testing. Kyla Bennett, a former EPA employee [said] that at recent rates of review, it would take thousands of years to assess all 86,000 chemicals currently approved for use. EPA staff ... say the agency's chemical programs remain understaffed, overwhelmed and burdened by still-ineffective regulations and a persistent culture that enables the chemical industry instead of counterbalancing it.
