Bisphenol A is one of the most common industrial chemicals and known to exert endocrine disruption activity. The aim of this study was the quantification of BPA in food stuffs on the Greek market. The applied LC-MS (liquid chromatography mass spectrometry) method was validated for linearity, limit of quantification, accuracy, precision and recovery. 41.7% of the canned solid phase samples, 25.0 % of the canned liquid phase samples and 43.8% of the soft drinks were positive. Mean BPA concentrations (and range) were 33.4± 4.4 ng/g (4.90 ± 0.64 to 66.0 ± 8.6 ng/g) in canned solid phase, 2.70 ± 0.08 ng/ml (1.90 ± 0.06 to 3.50 ± 0.11 ng/ml) in canned liquid phase and 2.30 ± 0.18 ng/ml (0.40 ± 0.03 to 10.2 ± 0.8 ng/ml) in soft drinks. The results of this study are comparable with those reported in the literature according to which higher concentrations of BPA were detected in the solid fraction of canned food compared to their liquid fraction.
