Nature : Daniel Zalko of the French National Institute for Agricultural Research in Paris and his colleagues have used radioactive tracers to prove that bisphenol A (BPA) is readily absorbed through the skin. The chemical, which is widely used as an additive in plastics and other consumer products, has been banned in Canada because of its implication in a range of medical conditions, including birth defects. Zalko and company’s findings might help clear up a mystery. Some people have higher levels of BPA in their bodies than would be expected if they ingested it in food or drink. Among the BPA-containing products that people routinely touch is the thermal paper used for store receipts.
