随着稀土元素在工,农业生产中和日常生活中的广泛应用,人们正在愈来愈多地接触稀土元素。因此,稀土元素的生物效应问题已成为一个亟待解决的研究课题。有关稀土元素的毒理学研究已有五十多年历史,本文就近年来稀土元素生物效应及其作用机制的研究作一简述。一、稀土元素的自由基效应自由基反应是生物体内的一种化学反应形式,在 With the widespread use of rare earth elements in industry, agricultural production and daily life, people are increasingly exposed to rare earth elements. Therefore, the biological effects of rare earth elements has become a research topic to be solved. Toxicological studies on rare earth elements have been in existence for more than fifty years. In this paper, the biological effects of rare earth elements and their mechanisms of action in recent years are briefly reviewed. First, the free radical effect of rare earth elements Free radical reaction is a form of chemical reaction in vivo, in the
