成都市人奶中有机氯化合物监测

Surveillance of Organic Chloride Compounds in Breast Milk in Chengdu

目的 了解成都市人奶中有机氯化合物含量。方法 采用奶样中有机氯农药快速色谱分离测定法。结果 人奶中六六六和DDT的检出率均为 10 0 % ,奶脂中六六六总量和DDT总量的平均值分别为 3 6 9mg/Kg和 1 0 4mg/Kg ,较 1986年成都市人奶中有机氯含量明显降低 (P <0 0 1) ;婴儿自母乳中摄入六六六和DDT的量仍高于相应的ADI值。结论 我市人奶中有机氯化合物残留水平较高 ,尤其对婴儿影响较大 。

Objective To make a survey of organic chloride compounds in breast milk in Chengdu.Method Fast chromatographic separation assey.Result Both hexachloro cyclohexane and DDT exist in the breast milk. The average amount of hexachloro cyclohexane and DDT are respectively 3 69mg/Kg and 1 04mg/Kg in the butterfat. They are significantly lower than those monitored in 1986( P <0 01). The result also indicates that the amount of hexachloro cyclohexane and DDT of infants by taking breast milk greatly exceeds the corresponding ADI. Conclusion The residual level of organic chloride compounds in breast milk remains high, moreover, it will have further influence on the infants. Department concerned should pay more attention to it.
