Bisphenol-A (BPA) is a principal reactant in the preparation of polycarbonate (PC) plastics and has been shown in in vitro cell proliferation studies to exhibit estrogen-like characteristics. Reusable baby bottles, water carboys, and other housewares are often made of PC. A high-pressure liquid chromatographic (HPLC) protocol was used to determine residual BPA in PC and BPA migrated to food simulants in contact with PC under controlled time/temperature conditions. Confirmation of BPA was performed by gas chromatography/mass spectrometry (GC−MS).
