镉是一种具有高度生物学活性的金属,可以引起机体的急慢性中毒。近十多年来,国内外学者用体内体外实验方法研究了镉的遗传学效应。然而,由于所用的种系、器官或镉化合物的不同,所得结论是有争议的。 Cadmium is a highly biologically active metal that can cause acute and chronic poisoning of the body. In recent ten years, scholars at home and abroad have studied the genetic effects of cadmium using in vitro and in vivo experimental methods. However, the conclusions drawn are controversial because of the differences in germline, organ or cadmium compounds used.
