The Risk Assessment Committee of the European Chemicals Agency (ECHA) has adopted an opinion to strengthen the harmonized classification and labeling (CLH) of bisphenol A (BPA), in line with a proposal by France regarding the substance’s adverse effects on sexual function and fertility. BPA is currently classified as a category 2 reproductive toxicant and would be reclassified as a category 1B reproductive toxicant.
The committee’s consensus-made action was based on “‘rock-solid’ multigenerational rodent studies” and tees up a final decision to be made by the European Commission. France’s reclassification proposal has received mixed responses [PDF] from member states and industry. If approved, the reclassification of BPA as category 1B would trigger Substance of Very High Concern (SVHC) criteria under REACH.
BPA is a monomer widely used in the production of polycarbonate plastics and epoxy resins and as a developer in thermal paper. In late 2013, ECHA followed up a German substance evaluation of BPA by issuing a request for further data on skin absorption and environmental exposure. The European Found Safety Authority (EFSA) also recently closed a public consultation period on a draft assessment of the human health risks of BPA via food exposure. A recent rodent study conducted by U.S. researchers at the National Center for Toxicology Research, however, concluded that orally-ingested BPA did not affect body weight, reproductive organs, or hormones at levels comparable to the amount Americans typically ingest.
