市售鱼类中双酚A、双酚S污染水平及风险评估

Contamination Levels and Risk Assessment of Bisphenol A and Bisphenol S in Commercially Available Fishes

目的:建立固相萃取和超高效液相色谱-串联质谱法测定鱼类中双酚A(Bisphenol A,BPA)及双酚S(Bisphenol S,BPS)的方法。方法:使用固相萃取和超高效液相色谱-串联质谱方法分析240份鱼类样品中BPA和BPS含量,并计算膳食暴露量和风险指数。结果:240份鱼类中均未检出BPA。BPS检出率为81.67%,含量检测最大值为65.31μg·kg^(-1),中位数为5.28μg·kg^(-1),平均值为12.99μg·kg^(-1)。结论:鱼类食品中检出BPS,未检出BPA。日常食用海水鱼或是淡水鱼都不会引起暴露风险。

Objective:To establish a method for the determination of Bisphenol A(BPA)and Bisphenol S(BPS)in fish by solid phase extraction and ultra-high performance liquid chromatography-tandem mass spectrometry.Method:The contents of BPA and BPS in 240 fish samples were analyzed by solid phase extraction and ultra-high performance liquid chromatogre-tandem mass spectrometry,and the dietary exposure and risk index were calculated.Result:BPA was not detected in 240 fish samples.The detection rate of BPS was 81.67%,the maximum value was 65.31μg·kg^(-1),the median value was 5.28μg·kg^(-1),and the average value was 12.99μg·kg^(-1).Conclusion:BPS and BPA were not detected in fish food.There is no risk of exposure from daily consumption of seawater fish or freshwater fish.
