本研究项目采用系统工程方法,对农业污染源及其对农畜产品的影响评价、农业非点污染负荷量、农村工业污染、生活污染以及重点污染区的污染现状等进行了深入的研究,获得了大量科学数据。初步认为,在上海郊区水体污染中,郊区工业污染物、畜禽粪尿、生活污染物和化肥的等标负荷比例依次为工业污染物>化肥>畜禽粪尿>生活污染物;提出了上海人均食物中 Cd 和蔬菜中硝酸盐日摄入量的科学数据;对上海郊区的重 This project uses systematic engineering methods to conduct an in-depth research on agricultural pollution sources and their impact on agricultural and livestock products, agricultural non-point pollution load, rural industrial pollution, domestic pollution and pollution status of key pollution areas, obtained A lot of scientific data. It is preliminarily believed that in the water pollution in the suburbs of Shanghai, the standard load ratios of industrial pollutants, livestock excrement, living pollutants and chemical fertilizers in the suburbs are industrial pollutants, chemical fertilizers, livestock excreta and living pollutants, and Shanghai Scientific data on per capita daily intake of Cd and nitrate in vegetables;
