山东省地下水污染特征与初步评价

以20世纪80年代以前地下水水质测试资料为背景，利用近几年工作中取得的大量水质测试资料，采用“污染指数法”进行区域地下水污染综合评价。研究表明：目前地下水仍以无机污染为主，但有机污染危害程度更大。“三氮”是浅层地下水的主要无机污染指标，其中又以硝酸盐污染为最。有机污染指标主要为1，2-二氯乙烷、1，1，2-三氯乙烷和四氯化碳等，裂隙岩溶水较孔隙水更容易受到有机物污染。

Characteristic and Preliminary Evaluation of Groundwater Pollution in Shandong Province

Regarding data of water quality before 1980s and rescent years as the background,based on wa-ter quality determination information,by using “pollution index method”,regional comprehensive evalua-tion of groundwater has been carried out.It is showed that main pollution is inorganic matter,but the pol-lution of organic compounds maybe more harmful.The three nitrogen is the main inorganic pollution inde-xes of shallow groundwater,while the nitrate pollution is the most serious.The organic pollution indexes is 1 ,2-dichloroethane,1 ,1 ,2-trichloroethane and carbon tetrachloride,the fracture karst water is more easily polluted than pore water by organic compounds.
