Concentrations of nine bisphenol analogues in food purchased from Catalonia (Spain): Comparison of canned and non-canned foodstuffs

摘要

The present study was aimed at assessing the exposure of an adult population to nine BPs analogues (BPA, BPS, BPF, BPB, BPAF, BPZ, BPE, BPAP and BPP) through a duplicate diet study. Up to 40 canned and non-canned food samples were purchased from Tarragona (Catalonia, Spain) and further analyzed. Three of the nine BPs - BPA, BPB and BPE - were detected in the food samples. BPA was found in 93% and 36% of canned and non-canned samples, respectively, with a mean concentration of 22.49 and 4.73 mu g/kg, respectively. Only one sample of canned asparagus (88.66 mu g/kg) exceeded the new threshold set by the European Commission (50 mu g/kg). BPB was found in canned and non-canned chicken and olive oil samples, with lower levels for canned chicken and non-canned olive oil. Finally, BPE was detected in non-canned mushrooms and nuts (2.40 and 12.35 mu g/kg, respectively). Based on the current results, dietary intake for BPA was estimated to be 24.9 and 3.11 mu g/day for canned and non-canned groups, respectively. The unexpected occurrence of BPs in non-canned products highlights the ubiquity of these compounds along the food production chain, beyond to the packaging.
