The European Commission last week proposed long-awaited criteria to help regulators determine which chemicals in pesticides and biocidal products such as hand disinfectants are—and are not—endocrine disruptors.

The European Union already has regulations in place to prohibit endocrine-disrupting chemicals in pesticides and biocides. The proposed criteria would be used to determine which chemicals fall under those regulations.

The proposal adopts the World Health Organization’s definition of endocrine disruptors as chemicals that alter hormones in animals and humans. Such chemicals have “a hormonal function, an adverse effect, and a causality between the two,” says the commission, which is the EU’s executive branch.

Neither the chemical industry nor endocrinologists are pleased with the proposed criteria.

“We are disappointed that we still do not have a set of scientific criteria that are suitable for the purposes of regulatory decision-making,” groups representing the European chemical and pesticide industries say. “Many substances which present no risk to human health or the environment will be identified as endocrine disruptors using this definition,” they predict.

In contrast, endocrinologists are calling the criteria too restrictive, saying the proposal would result in few chemicals being identified and regulated as endocrine disruptors.

“The European Commission has set the bar so high that it will be challenging for chemicals to meet the standard, even when there is scientific evidence of harm,” says Henry M. Kronenberg, president of the Endocrine Society.

Sounds like a more realistic assessment of these possible hazards. Any toxicity is dependent real-life exposure to the whole organism as well as consideration o0f ADMET principles used in evaluating pharmaceuticals.
