浙江省恶性肿瘤的环境地球化学研究

利用区域地球化学资料开展浙江省恶性肿瘤的地球化学环境影响因素研究.恶性肿瘤标化死亡率受地球化学综合因素影响,应用微量元素对各类恶性肿瘤标化死亡率的相关阵和逐步回归方程定量地研究各类恶性肿瘤与地质环境中微量元素的关系.胃癌、肝癌、肺癌、肠癌、食管癌、白血病与铁族元素及Ba、Zr、Mo的背景密切相关,宫颈癌、鼻咽癌、乳腺癌与Cu、Pb、zn元素的背景相关,稀土元素对恶性肿瘤有压抑作用.浙江省恶性肿瘤的流行受区域地质构造控制和地球化学环境制约,具明显的地域性分布特征.

Geochemical Research about Malignant Tumors of Zhejiang Province

This article researched on the geochemical envimnment effects of malignant tumors by using regional geochemical material of Zhejiang province The death rate of malignant tumors was influenced by the geochemical synthetical factor.Using intrrenelated Matrix and progreessively regression equation of trace elements to malignat tumors death rate,we could quantitative research on the ielationship between every kind of malignant tumors and trace elements in geologic environment. Gastric cancer, liver cancer, lung cancer, intestinal cancer, esophagus cancer, as well as leukemia were closely related to the background of iron race elements and Ba,Zr,Mo elements, Cervical Cancer,nasopharyngeal darcinoma and bleast cancer were related to the background of Cu,Pb,Zn elements.Rare - earth elements had inhibition to malignant tumors.The malignant tumors' epidemic of Zhejiang province had evident regional distribution features because of the conuol of regional geologic structure and geochemical environment.
