镉是常见的环境和工业毒物 ,可通过被污染的食物、饮用水、吸烟和职业接触等途径进入人体 ,生物半衰期长达 10至 3 0年。现已证实 ,镉对骨骼、肾脏、肝脏、生殖和免疫等器官系统有损害作用 ,但其广泛的毒作用机理尚不十分清楚。近年来 ,有些学者研究镉对细胞信号转导系统的影响
Cadmium is a common environmental and industrial poison that enters the human body through contaminated food, drinking water, smoking and occupational exposure, with a biological half-life of 10 to 30 years. Has been confirmed that cadmium on bone, kidney, liver, reproductive and immune organ system damage, but its broad toxic mechanism of action is not yet clear. In recent years, some scholars have studied the effect of cadmium on cell signal transduction system
