镉是一种常见的工业和环境毒物,在环境中不能被生物降解,相反它却能够经食物链的生物放大作用,成千百倍地富集。在各种水产品鱼、贝等中大量蓄积。土壤中的镉可被谷物吸收,最终通过饮水、食物和呼吸进入人体,在人体器官中的大量累积,对人的身体健康造成了极大的危害。研究表明,睾丸也是镉的重要靶器官之一,且睾丸对于镉的毒性极其敏感~([1])。镉与其他有毒重金属铅、汞和雌激素样化合物双酚A一样,可导致精子数量减少和 Cadmium is a common industrial and environmental toxicant that can not be biodegraded in the environment but rather enriched thousands of times through the biomagnification of the food chain. In a variety of aquatic products such as fish, shellfish and other large accumulation. Cadmium in the soil can be absorbed by cereals, eventually entering the human body through drinking water, food and breathing, resulting in a great deal of damage to human health due to the large accumulation in human organs. Studies have shown that testis is also one of the important target organs of cadmium, and testis is extremely sensitive to the toxicity of cadmium ~ ([1]). Cadmium, like other toxic heavy metals such as lead and mercury, and the estrogen-like compound bisphenol A, can cause a reduction in sperm counts and
