中国癌症与土壤环境中钒元素的关系

The relation between the cancer in China and V element in the soil environment

利用土壤环境中钒元素资料 32 335个数据和癌症死亡调查资料 7870 80例 ,研究了癌症死亡率与人群生存区土壤环境中钒元素的关系。结果表明 ,仅胃癌、大肠癌死亡率与钒元素有相关性 ,等级相关系数分别为 - 0 476 9(P <0 0 0 5) ,- 0 31 79(P <0 0 5)。

On the basis of the investigation of 787 080 cases about the death of the cancer and 32 335 data of V element in soil in multitudinous areas,the paper studies the relationship between the mortality and V element in soil in the inhabited areas The result shows that the mortality of gastric cancer,intestinum crassum cancer is obviously correlated to V in soil and correlation coefficient gradation are individually -0 476 9(p<0 005),-0 317 9(p<0 05)
