摘要
利用土壤环境中钍元素767 个数据,癌死亡调查资料787 080 例,研究了胃癌、食管癌、肝癌、宫颈癌、肺癌、大肠癌、白血病、鼻咽癌、乳腺癌死亡率与人群生存区土壤环境中钍元素的关系。结果表明,胃癌、食管癌、宫颈癌、肺癌、鼻咽癌死亡率与钍元素有相关性、等级相关系数分别为-0.3857(P<0 .025),-0.3256(P<0 .05),-0.454 2(P<0 .01),-0.382 8(P<0.025) ,0.615 3(P< 0.000 5) 。
Relationship between the mortality of gastric,esophagus,liver,cervix,lung,large intestine,letestine,leukemia,nasopharyngeal,breast cancer and Th element in soil environment is studied in this article,based on 767 data of Th element in soil environment and 787 thousands examples of investigation information about the cancer mortality.The result shows that the mortality of gastric,exophagus,cervix,lung,nasopharyngeal cancer is obviously correlation to Th in soil and the correlation coefficient gradation is respectively -0.385 7(P<0.025),-0.325 6(P<0.05),-0.454 2(P<0.01),-0.382 8(P< 0.025 ),0.615 3(P<0.000 5)。
