Researchers call Chemical Testing 'Inadequate'

An article on CNN on Tuesday has commented that the United States Environmental Protection Agency has not used sufficient research to determine the safety of products containing bisphenol-A, according to researchers from the Endocrine Society. According to the comments made by the Endocrine Society, the EPA's studies fail to take into account the effects low dosages of bisphenol-A can have on organisms, as well as exposure during particularly vulnerable periods such as pregnancy. According to William Hudson, CNN's Medical Associate Producer:

For a typical poison, a higher dose correlates directly with greater toxicity, but endocrine disrupting chemicals like BPA may be counter-intuitively more potent at lower levels, and during "windows of vulnerability" such as pregnancy, explains a 2009 scientific statement by the Endocrine Society.

That poses a problem for regulatory agencies' screening tests, which are based on traditional toxicology and do not detect the low-dose effects of chemicals on the endocrine system, said Frederick vom Saal, who co-authored the Endocrine Society's new statement.

The Endocrine Society also issued a revised definition for endocrine-disrupting chemicals, saying that any chemicals "that interfere with any aspect of hormone action should be presumed to produce adverse effects," regardless of whether the adverse effects are well understood.
