【摘要】 本文根据计算排毒系数的方法确定了主要污染源和污染物,又根据食入、饮进、呼吸等量建立了权重系统,由此而计算了中国不同农业区域的污染指数。结果表明,重污染区集中在长江、黄河流域的粮、棉产区,而且我国农业环境中BHC、DDT污染程度是向南或向北逐渐减弱。更多还原

【Abstract】 Based on emission factor calculated, the major pesticide pollutants and their sources were identified. The pollution indices were counted for different agricultural regions in China. The results show that the heavily polluted regions usually located in the grain and cotton growing area between the Yellow River and the Yangzi River. The extent of pollution by BHC and DDT in agricultural environment gradually decreases toward the northern and southern parts of China.更多还原
