摘　　要：通过对浙江某地食道癌、胃癌、肝癌和膀胱癌等癌症高发区地质环境研究发现,与相邻的低发区相比,研究区土壤质地黏重,有机质含量高,居民饮用的井水中亚硝酸盐、氨氮、硝酸盐严重超标。食道癌死亡率高达269/10万,远高于中国死亡标化率10.02/10万。研究认为,土壤黏重导致井水滞流和亚硝酸盐升高,是研究区食道癌高发的诱发的主要原因。Environmental geological survey in a certain high incidence area of esophageal cancer shows that soil parent materials of this area are more viscous and heavy and have higher organic matter than the soil parent materials in low-incidence areas,and nitrite,N-NH3 and N-NO3-in drinking water wells of this area are seriously higher than their standards.The mortality of esophageal cancer is as high as 269/100 000,by far higher than the national standardized mortality of 10.02/100 000.Studies show that soil viscocity and heaviness cause slower water flow and higher nitrite content in the well,which seems to be the main cause for high incidence of esophageal cancer in the study area.
