摘要
根据土壤环境中767个铪元素资料和787080例癌症死亡调查资料,研究了癌症死亡率与人群生存区土壤环境中铪元素的关系。结果表明,食管癌、肝癌、宫颈癌和鼻咽癌死亡率与铪元素有相关性,等级相关系数分别为-0 3544(p<0 05),0 3916(p<0 025),-0 3149(p<0 05)0 4547(p<0 01)。
On the basis of the investigation of 787 080 cases about the death of the cancer and 767 data of Hf element in soil in multitudinous areas. The relationship between the mortality and Hf element in soil in the inhabited areas are studied in this paper. The results show that the mortality of esophagus cancer, cancer of the liver, cervical cancer, and nasopharyngeal carcinoma are obviously correlated to Hf in soil, and the correlation coefficient gradation are 0.354 4(p<0.05), 0.391 6(p<0.025), -0.314 9(p<0.05), 0.454 7(p<0.01).
