Bisphenol A (BPA) is an endocrine disruptor. It is used as monomer of plastic polycarbonate (PC) or additive in other plastic products. If bisphenol A released from daily necessities, such as baby bottles, sports water bottles and all kinds' food containers, would lead to health concerns. One hundred samples including various types of plastic containers were collected from March to October, 2010. Materials identification was conducted by Fourier transform infrared Spectroscopy. Six leaching conditions were applied according to the regulation announced by Department of Health, Executive Yuan. All the dissolutions were analyzed by HPLC on a column of Inertsil ODS-2, using acetonitrile : water (1:1, v/v) as mobile phase and monitored by fluorescence detector at Ex 275 nm and Em 304 nm. Bisphenol A standard in the range of 2-40 ng/mL showed a good correlation (R^2 = 0.9999). Bisphenol A migration was not detected, including 11 pieces of PC and other plastic materials under six leaching conditions (< 2 ppb).
