Bisphenol A (BPA), a contaminant which may be present in the coating of cans, was determined in 45 canned beverages and 21 canned food items from the Belgian market. Beverages had an average BPA concentration of 1.0 ng/ml, while canned foods had a higher average concentration of 40.3 ng/g. The amount of BPA present in food items was dependent on the type of can and sterilisation conditions rather than the type of food. For example, BPA was not detected in non-canned beverages (<0.02 ng/ml), while non-canned food items had a very low average concentration of 0.46 ng/g. Using detailed information from the Belgian food consumption survey, the BPA intake of adults through canned foods and beverages was estimated to be 1.05 µg/day or 0.015 µg/kg body weight/day (assuming an average adult weight of 70 kg). Intake assessments, based on urinary metabolite concentrations from the literature, resulted in slightly higher BPA intakes (range 0.028-0.059 µg/kg body weight/day). This suggests that sources other than canned foods and beverages contribute to BPA exposure in humans.
双酚 A（BPA）是罐头涂层中可能存在的污染物，在比利时市场的 45 种罐装饮料和 21 种罐装食品中进行了测定。饮料中的 BPA 平均浓度为 1.0ng/ml，而罐装食品的平均浓度则更高，为 40.3ng/g。食品中 BPA 的含量取决于罐头类型和杀菌条件，而与食品类型关系不大。例如，非罐装饮料中未检出 BPA（<0.02ng/ml），而非罐装食品的平均浓度则非常低，为 0.46ng/g。利用比利时食品消费调查的详细信息，估算出成年人通过罐装食品和饮料摄入的 BPA 为 1.05µg/天或 0.015µg/kg 体重/天（假设平均成年人体重为 70kg）。根据文献中尿代谢物浓度进行的摄入量评估结果显示，BPA 摄入量略高（范围为 0.028-0.059µg/kg 体重/天）。这表明，人类接触 BPA 的来源除了罐装食品和饮料之外还有其他途径。
