摘要
上海市郊农业生产中的自身污染，目前主要有农药、化肥、畜禽粪尿和农用塑料薄膜。７０年代以前，上海曾施用过有机汞、有机氯等农药，对环境的影响较大。８０年代以来，影响较大的农药主要是有机磷和菊酯类；化肥主要是氮肥施用过多，导致蔬菜硝酸盐含量过高；畜禽粪尿已成为郊区突出的新污染源，造成水体的严重污染；各类农用塑料薄膜也是必须重视的新潜在污染物。
Thesources of self-pollution in agriculture production of Shanghai suburbs are mainlythe agriculture pesticides,chemical fertilizers,urine and excrements of fowls and animalsand the agriculture plastic films at present.

During the eighties,thepesticides making great influence were mainly organic phosphorus and tyiethroids;the fer-tilizer causing great influence were mainly the overused nitrogenous fertilizer which causedexcessive nitrate accurnulation in vegetables. And the urine and excrements of fowls andanimals have become a major pollution source in Shanghai suburbs causing serious pollu-tion in vvater.Meanwhile,various kinds of plastic films have been another potential pollu-tant to which must pay serious attention.
