本文从人体流行病学调查、动物实验、组织培养,以及细菌、生物学等方面分析了金属致癌问题。一、金属致癌的流行病学与动物实验金属致癌是从接触金属的矿山、冶炼厂等工人癌症发病率高的流行病调查发现的,以后通过动物实验证明,金属因其化合物不同,而 This article analyzes metal carcinogenicity issues from human epidemiological investigations, animal experiments, tissue cultures, as well as bacteria and biology. I. Epidemiology and animal experiments of metal carcinogens Metal carcinogenesis was discovered through surveys of epidemics with high incidence of cancer among workers exposed to metal mines, smelters, etc. Later, animal experiments have shown that metals are different due to their different compounds.
