重铬酸盐、铬酸盐等六价铬化合物广泛应用于工业上,而且由于含六价铬化合物的工业三废污染环境,接触六价铬的人群不断增多。六价铬的一般毒性已基本阐明。关于其致癌性和致突变性的问题已有文献报导,认为六价铬化合物具有致癌和致突变的性质。至于六价铬的致畸问题文献报导尚甚少。目前认为,致癌性、致突变性与致畸性之间有密切关系,而且我们调查铬对
Hexavalent chromium compounds such as dichromate and chromate are widely used in industry, and due to the industrial three-waste pollution environment containing hexavalent chromium compounds, the number of people exposed to hexavalent chromium is increasing. The general toxicity of hexavalent chromium has been basically clarified. With regard to its problem of carcinogenicity and mutagenicity, it has been reported in the literature that hexavalent chromium compounds are carcinogenic and mutagenic. As for the teratogenic problems of hexavalent chromium, there are few reports in the literature. At present, there is a close relationship between carcinogenicity, mutagenicity and teratogenicity, and we have investigated chromium
