摘　　要：从环境地理学和环境化学的角度出发,研究了饮用水中亚硝酸盐以及微量元素的分布与癌症发病率的关系。在对江苏省如皋地区饮用水水样检测的基础上,指出研究区的饮用水中虽然亚硝酸盐严重超标,但是并没有与癌症发病率形成相关性。同时运用方差分析方法对饮用水中的微量元素进行研究,选出了若干种与如皋地区的癌症发病率存在很强相关性的微量元素,并讨论了这些元素的分布特征与癌症发病率的具体关系。The correlation between the distribution of nitrite and trace elements in the water and the incidence of the cancer is studied from the view of environmental geography and environmental chemistry in the paper. On the basis of the monitoring of the drinking water samples in Rugao of Jiangsu province it is shown that although the nitrite in the drinking water has gone beyond the standard very much it hasn't shown the correlation between the distribution of nitrite and the incidence of the cancer. And several trace elements which correlate with the incidence of the cancer are decided through the variance analysis. Then the detail correlation between the distribution character of these trace elements and the incidence of the cancer is discussed.
