河南省农药污染现状评价

Evaluation of Present Situation of Pesticide Pollution(EPSPP)in Henan Province

1988～1989年对河南的农药残留污染现状进行了评价研究。结果表明:DDT 的综合污染指数为0.055,其在河南的污染已经消除;六六六的综合污染指数为0.154,在肉、蛋、奶、植物油中的残留污染仍较严重,其检出率为100%,超标率12.5%～50%,残留量tra～5.271ppm,污染综合指数0.473～0.491,对其它环境因素污染较轻。有机磷和呋喃丹杀虫剂的残留污染日趋严重;残留比较突出的是蔬菜和瓜果,检出率9%～50%,超标率0～45%,残留量0～38ppm;大米和小麦残留较轻,检出率10.7%～10.8%,超标率7.14%～8.1%,残留量0～11ppm。

The study and evaluation of the pesticide pollution were carriedout in Henan in 1988～1989.The Complex Pollution Index(CPI)of DDT is0.055 and its pollution has disappeared in Henan.The CPI of BHC is 0.154;its residual pollution in meat,egg,milk and vegetable oil is rather serious.Itsdetection ratio,exceed standard ratio,amount of residue and CPI are 100%,12.5%～50%,tra～5.27lppm and 0.473%～0.491 respectively.The pollutions inother environmental facfors are slight.The residual pollution of the organicphosphorus pesticides and the carbofuran are becoming serious.Pollution invegetables,melons and fruit are more serious;the detection ratio,exceed sta-ndard ratio,amour of residue are 9%～50%,0～45%,and 0～38ppm respectively.Pollutions in rice and wheat are also serious;the detection ratio,exceedstandard ratio and amount of residue are 10.7%～10.8%,7.14%～8.1% and0～11.0ppm reseetively.
