摘　　要：目的 调查我国动物性食品中有机磷农药（OPPs）残留的污染状况,进行我国人群的膳食暴露风险评估.方法 采用方便抽样法于2012年在我国13个省份的20个采样点采集115份动物性食品样品,包括猪肉、牛肉、鸡蛋、鱼肉、鸡肉、羊肉和牛奶等7种,通过双气相色谱-双脉冲火焰光度法检测了包括代谢产物在内的58种OPPs残留组分;以累积膳食暴露和高端暴露评估被调查地区人群由于摄人动物性食品而导致的OPPs膳食暴露风险.结果 动物性食品中OPPs污染水平较低,含量水平在未检出（ND） ～0.343 mg/kg之间,总检出率为37.4％（43/115）,其中牛奶、鱼肉、猪肉中OPPs检出率较高,分别为12/17、9/16及7/16.在115份动物性食品样品中共检出甲胺磷、甲基内吸磷、丙线磷、敌敌畏、久效磷、甲基谷硫磷、乐果、乙酰甲胺磷、甲拌磷和甲基嘧啶磷10种OPPs.我国被调查地区人群由于摄入动物性食品的累积膳食暴露量为0.12 μg·kg^-1·d^-1,占累积人体每日允许摄入量（ADI）的7.29％.结论 调查地区动物性食品中OPPs污染水平较低,但仍有久效磷、甲胺磷等个别禁用OPPs检出;调查地区人群由于摄入动物性食品而对OPPs产生的膳食暴露风险较低.Objective To investigate the levels of organophosphorus pesticides （OPPs） in animal foods and to assess the diet expossure risk of OPPs to Chinese population.Methods 115 samples,including pork,beef,mutton,chicken,fish,eggs,and milk were collected from 13 provinces in China,were analyzed by dual gas chromatography-dual pulsed flame photometry （GC-PFPD） for the contamination of 58 organophosphorus pesticide residues including their metabolites.The cumulative exposure assessment and high-end exposure assessment were used to assess the diet expossure risk of OPPs to Chineses population.Results The contamination levels of OPPs in animal foods were in the range of not detected （ND）-0.343 mg/kg,and the total detection rate was 37.4% （43/115）.OPPs were frequently detected in samples of milk,fish and pork compared with other animal foods with the detection rate of 12/19,9/16 and 7/16,respectively.The cumulative exposure amount of 10 OPPs to Chinese population was 0.12 μg · kg^-1 · d^-1,which accounted for 7.29% of the ADI.Conclusion The residue levels of OPPs were low in animal food in the surveyed areas in China with some banned individual OPPs,such as methamidophos and monocrotophos,were detected.The dietary exposure risk of OPPs raised by the intake of animal foods in surveyed areas of China was low.
