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。
From 1988 to 1989, the status quo of pesticide residue pollution in Henan was evaluated. The results showed that the comprehensive pollution index of DDT was 0.055 and its pollution in Henan had been eliminated. The comprehensive pollution index of 666 was 0.154, and the residual pollution in meat, egg, milk and vegetable oil was still serious. The detection rate was 100%, exceeding the standard rate of 12.5% ~ 50%, the residual amount of tra ~ 5.271ppm, the comprehensive index of pollution 0.473 ~ 0.491, less pollution to other environmental factors. Organic phosphorus and carbofuran pesticide residues increasingly serious pollution; residues are more prominent in vegetables and fruits, the detection rate of 9% to 50%, 0 to 45% exceed the standard rate, the residual amount of 0 ~ 38ppm; rice and wheat residues Light, the detection rate of 10.7% to 10.8%, excessive rate of 7.14% to 8.1%, the residual amount of 0 ~ 11ppm.
