Abstract
Bisphenol A (BPA) is an important organic intermediate that is an estrogen and an environmental endocrine disrupting chemical. Bisphenol A is used widely in the production of consumer goods, polycarbonate plastics, epoxy resins. A large amount of studies have indicated that BPA might affect human health. In this work, four different tea (Tieguanyin tea, Black tea, Maofeng tea, Jasmine tea) were tested to verify if they were able to increase the BPA release from the PC cup. High performance liquid chromatography (HPLC) with fluorescence detection (FLD) was used to quantify BPA. Result showed that the heating time and temperature could have an influence on BPA migration from polycarbonate plastic. BPA migrated into tea water from polycarbonate plastic, especially when heated to high temperatures. Relatively high levels of BPA were found to be released into food simulants water from high concentration tea water.
