Concentrations of bisphenol A in the composite food samples from the 2008 Canadian total diet study in Quebec City and dietary intake estimates

A total of 154 food composite samples from the 2008 total diet study in Quebec City were analysed for bisphenol A (BPA), and BPA was detected in less than half (36%, or 55 samples) of the samples tested. High concentrations of BPA were found mostly in the composite samples containing canned foods, w...

Sumario:A total of 154 food composite samples from the 2008 total diet study in Quebec City were analysed for bisphenol A (BPA), and BPA was detected in less than half (36%, or 55 samples) of the samples tested. High concentrations of BPA were found mostly in the composite samples containing canned foods, with the highest BPA level being observed in canned fish (106 ng g(−1)), followed by canned corn (83.7 ng g(−1)), canned soups (22.2–44.4 ng g(−1)), canned baked beans (23.5 ng g(−1)), canned peas (16.8 ng g(−1)), canned evaporated milk (15.3 ng g(−1)), and canned luncheon meats (10.5 ng g(−1)). BPA levels in baby food composite samples were low, with 2.75 ng g(−1) in canned liquid infant formula, and 0.84–2.46 ng g(−1) in jarred baby foods. BPA was also detected in some foods that are not canned or in jars, such as yeast (8.52 ng g(−1)), baking powder (0.64 ng g(−1)), some cheeses (0.68–2.24 ng g(−1)), breads and some cereals (0.40–1.73 ng g(−1)), and fast foods (1.1–10.9 ng g(−1)). Dietary intakes of BPA were low for all age–sex groups, with 0.17–0.33 μg kg(−1) body weight day(−1) for infants, 0.082–0.23 μg kg(−1) body weight day(−1) for children aged from 1 to 19 years, and 0.052–0.081 μg kg(−1) body weight day(−1) for adults, well below the established regulatory limits. BPA intakes from 19 of the 55 samples account for more than 95% of the total dietary intakes, and most of the 19 samples were either canned or in jars. Intakes of BPA from non-canned foods are low.
