摘要
依据土壤元素资料2069448个数据及胃癌死亡调查资料184920例,研究了胃癌死亡率与人群生存土壤环境中As、Cd、Co、Cr等60多个元素的相关性。结果表明,Co、Cu、Hg、Pb元素与胃癌死亡率有相关性,并列举出其等级相关系数。
The correlation over 60 kinds elements between the death rate of gastric carcinoma and soil elements in the gathering areas of people has been studied based on 184920 cases of death caused by gastric carcinoma and 2069448 data of soil elements. The result show that the death rate is correlative to those elements such as Co,Cu,Hg,Pb etc., and correlation coefficients of various grade were given.
