铬广泛存在于生产和生活环境中,可通过各种途径进入人体。铬的生物学作用尚未完全阐明,不少人认为三价铬(Cr~(3+))是人体的必需微量元素,参与糖代谢过程,称为“糖耐量因子”。一般认为六价铬(Cr~(6+))对生物体有很强的毒性。本文就铬的胚胎毒性作用研究概况作 Chromium is widely found in the production and living environment, can enter the human body through various channels. Chromium biological role has not been fully elucidated, many people think that trivalent chromium (Cr ~ (3+)) is the body’s essential trace elements involved in glucose metabolism process, known as the “glucose tolerance factor.” It is generally believed that hexavalent chromium (Cr 6+) is highly toxic to organisms. In this paper, the embryonic toxicity of chromium research overview
