A study was performed to establish a comprehensive database on the migration of bisphenol A from polycarbonate baby bottles into water during exposure to microwave heating. For that purpose polycarbonate baby bottles from 18 different brands sold in Europe were collected. The initial residual content as well as the migration of bisphenol A after microwave heating were determined. The residual content of bisphenol A in the polycarbonate baby bottles ranged from 1.4 to 35.3 mg.kg-1. The migration study of bisphenol A into water was performed by placing a polycarbonate bottle filled with water into a microwave oven and heating to 100°C. After heating, the amount of bisphenol A in the water was analysed by GC-MS. The whole procedure of microwave heating and analysis was repeated two times for the same bottle. Thus, 3 migration extracts were prepared for each test specimen. The migration of bisphenol A into water ranged from < 0.1 to 0.7 µg.l-1. There was no correlation between the amount of the residual content of bisphenol A in the bottles and the migration of bisphenol A into water. Furthermore, there was also no correlation between the amount of bisphenol A in the consecutive migration extracts. The data presented shows that during 3 microwave heating cycles of a baby bottle made from polycarbonate, no effects of microwave radiation on the migration of bisphenol A into water from polycarbonate can be observed. All levels found were well below the Specific Migration Limit of 0.6 mg.kg-1 specified for bisphenol A in the Commission Directive 2004/19/EC.
