摘　　要：水体鱼类有机农药的污染影响到生态和人类健康的安全。本文通过对龙江河多种野生鱼类中鱼肉、鱼骨、鱼鳞、鱼鳃、鱼鳍、内脏6个部位的4种有机磷农药(乐果、毒死蜱、对硫磷、马拉硫磷)进行含量测定及分析,可知龙江河多种野生鱼体内均检测出对硫磷,部分鱼类检测出马拉硫磷。通过对鱼体各部位的有机磷含量分析,发现龙江河野生鱼体内的有机磷多富集在鱼鳃和内脏中,鱼骨、鱼鳍等部位因为其生长性质,其有机磷含量也是随着鱼的生长而增加的。采用危险系数法对所测鱼类鱼肉部位进行健康风险评价,结果表明它们的THQ值均小于1,无明显健康风险。建议龙江河流域居民只食用鱼肉部位,不要食用鱼体的其他部位。The pollution of organic pesticides in fish in water bodies affects the safety of ecology and human health.This article determined and analyzed the content of four organic phosphorus pesticides(dimethoate,chlorpyrifos,parathion,and malathion)in the flesh,bones,scales,gills,fins,and viscera of various wild fish species in the Longjiang River.It was found that parathion was detected in various wild fish species in the Longjiang River,and malathion was detected in some fish species.Through the analysis of the organic phosphorus content in various parts of the fish body,it was found that the organic phosphorus in the body of wild fish in the Longjiang River is mainly enriched in the gills and viscera of the fish.Due to their growth properties,the organic phosphorus content in fish bones,fins,and other parts also increases with the growth of the fish.The hazard coefficient method was used to evaluate the health risk of the measured fish meat parts,and the results showed that their THQ values were all less than 1,indicating no significant health risk.It is recommended that residents in the Longjiang River Basin only consume fish parts and not other parts of the fish body.
