EPA defends chemical testing of low-dose hormone effects
http://www.environmentalhealthnews.org/ehs/news/2013/epa-low-dose
"The U.S. Environmental Protection Agency has concluded that current testing of hormone-altering chemicals is adequate for detecting low-dose effects that may jeopardize health. This comes in response to a report written last year by 12 scientists who criticized the government's decades-old strategy for testing the safety of many chemicals found in the environment and consumer products. The scientists specifically focused on a phenomenon called "nonmonotonic dose response," which means that hormone-like chemicals often do not act in a typical way; they can have health effects at low doses but no effects or different effects at high doses. The EPA's conclusion was commended by the chemical industry, which called the evidence "at best, very weak." But a Tufts University scientist said it "flies in the face of our knowledge of how hormones work.""
