摘要
本文综述了生态环境中镉对生物毒性作用机理及硒对镉毒性拮抗作用研究的进展。镉的毒性作用与镉诱发自由基、诱导脂质过氧化以及对其它化学元素的干扰有关,同时也与金属硫蛋白(MT)有着密切关系。硒对镉的拮抗作用与硒的抗氧化作用、与镉形成硒镉复合物以及改变镉在体内的的分布有关。
Research progress in cadmium toxicity mechanisms and the antagonistic mechanisms of selenium to cadmium were reviewed. The toxic effects of cadmium are relevant to the cadmium-induced free radicals and lipid peroxidation and the effects of cadmium on other elements.They also have close relationship with metallothionein.The antagonism of selenium to cadmium is due to the antiox-idative effects of selenium, the formation of Se-Cd complexes and the selenium-induced redistribution of cadmium in vivo.
