摘要
水环境是环境雌激素的最大储存库.环境雌激素通过食物的传递进入动物体内,类似于雌激素的功能.环境雌激素可导致水生动物性别特征丧失和后代不能繁殖;可引起水蚤性别比例失调,蜕皮率下降,导致软体动物性畸形和超雌性化现象;导致鲤鱼等生殖器畸形,引起鱼类种群生存力和资源量下降.壬酚(NP)、双酚A(BPA)和E2在河水、水生附着生物和底栖生物之间的生物积累与放大倍数在18～1200倍之间,环境激素通过食物链的生物放大作用比通过水体的传递对鱼类等水生生物的危害更大,并且在河流等的枯水期对水生动物的影响更大.文章讨论了环境雌激素的降解与研究前景.
The biggest depositary of environmental estrogens is water environment. Environmental estrogens usually pass through the food chain into the bodies of aquatic animals, where they act as pseudo-hormones. Environmental estrogens can cause the aquatic animals to have confused characteristics, affect the development, differentiation and reproduction of aquatic animals, change the sex ratio, cause sex abnormality, and so on. The trend of the future research in this field was also briefly discussed.
