为了观察农药销售结构改变后成都地区代表人群膳食中的有机氯、有机磷农药残留情况和这两类主要农药的平均摄入水平，于１９９６年进行了总膳食研究。结果：测定的谷类、蔬菜、水果等５类食物样品中６种有机磷农药（乐果、敌敌畏、对硫磷、倍硫磷、马拉硫磷、甲拌磷）残留量均低于检出限；城乡居民９种食物样品中ＨＣＨ（六六六）、ＤＤＴ（滴滴涕）有机氯农药残留量，除城乡谷类、豆及坚果类低于检出限外，薯类、蔬菜类、水果类、肉类、蛋类、水产类、乳类均有检出。与８０年代初有机氯农药监测结果比，动物性食品中ＨＣＨ和ＤＤＴ残留量均有明显的下降，但目前ＨＣＨ、ＤＤＴ摄入量仍远高于南方二区和全国平均水平。
In order to observe the presence of organochlorine and organophosphorus pesticide residues in the diet of the representative population in Chengdu after the pesticide sales structure was changed and the average intake of these two types of pesticides, a total dietary study was conducted in 1996. Results: The residues of six kinds of organophosphorus pesticides (dimethoate, dichlorvos, parathion, fenthion, malathion and phorate) in the five kinds of food samples of cereals, vegetables and fruits were lower than the detected ones Residues of organochlorine pesticides (HCH) and DDT (DDT) in nine food samples of urban and rural residents were lower than the detection limits except that of urban and rural cereals, beans and nuts, and that of potato, vegetables, fruits, Meat, eggs, aquatic products, milk are detected. Compared with the monitoring results of organochlorine pesticides in the early 1980s, the residues of HCH and DDT in animal food decreased significantly, but the intake of HCH and DDT is still far higher than the average of the second district in the south and the national average.
