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.

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。

This simulation study deals with the biodegradation processes of petroleum hydrocarbons and phenol substances in soil and their relations with soil enzyme activities. Results show that the biodegradation rates of these pollutants are higher when in low concentra tions and under normal soil moisture condition than in high concentrations and under waterlogged. Chemical structures of pollutants also give an influence to the rates:a lower biodegradation rate can be found for the pollutant having a more stable and complex chemical structure. The biodegradation process of hydrocarbons and phenol relates closely with the activities of soil invertase and polyphenoloxidase respectively, and hence, the intensity of these activities could be respectively used as an index indicating the pollu tion degree of soil by petroleum hydrocarbons and phenol substances. To say the least, a certain extent of pollution by these pollutants does not exert an obvious influence un favourable to the biological activities or transformations of C, N, and P in soil under normal soil moisture condition. Based on these results, suggestions on land treatment of these pollutants are put forward.

By research and computation the paper determines the mean value ofheavy metal elements in rock weathered shells in the catchment area around Daya Bay. At the same time it has set up an equation group from grainsizing data of the sediments, and the data of heavy metal element contents in deep strata sediments which were taken from 13 sampling stations inside Daya Bay in 1988, and computated the mean contents of heavy metal elements in sediments of the bay. According to the two data groups,mean background value for heavy metal elements inside the area was determined. On ground of that and again by grainsize relation, a square equation was arranged, computating the background value for heavy metal elements of each station in the bay. By application of these results and the measured results of heavy metal element contents of the sediments in Daya Bay of 1988, a formula of mathematical relationship was set up,and the heavy metal element contents in the sediments which were carried through manmade effects were computated, understanding the extent of pollution.

根据大亚湾的自然条件认为,大亚湾沉积物的物质来源是其周围集水区的岩石风化壳,并计算了其风化壳中重金属元素的平均丰度值;又根据沉积物的粒度和深层沉积物重金属元素的含量资料,列方程计算出湾内沉积物中重金属元素的平均含量,根据这两组数据,确定该区域内重金属元素的平均背景值。再通过粒度关系,计算得出大亚湾内各站沉积物中重金属元素的背景值。应用此结果和大亚湾沉积物重金属元素实测结果,计算了由人为影响带入沉积物中的重金属元素含量,了解其受污染的程度。
