Bisphenol A, also called BPA, is an industrial chemical introduced in the 1960s. It is primarily used to make polycarbonate plastics and epoxy resins. Today BPA is found in many products such as water bottles, dental fillings and sealants, dental and medical devices, eyeglass lenses, digital media (e.g. DVDs, CDs), household electronic and sports equipment, as well as in toys and other consumer goods. According to several studies carried out on BPA, the chemical not only endangers human health and both aquatic and terrestrial environments, but also can affect mating behavior in some species leading to interspecies reproduction.
