环境激素是指从环境中进入人体和动物体内并干扰其正常内分泌机能的化学物质,它们具有类似雌性激素的作用,能对生物体内的正常激素功能施加影响,导致人类和动物的生殖功能下降、生殖器肿瘤、免疫力降低,并引起各种生理异常。绝大部分环境激素都是由人类活动释放到环境中,使人类的生存和繁衍受到威胁,现已成为继臭氧层空洞、温室效应之后的又一全球性环境问题。目前全世界大约有8万种化学物质直接为人类所用,许多有害化学物质在使用过程中进入环境并引起环境污染,但这些有害物质并非都是环境激素。
Environmental hormones are chemicals that enter the human body and animals from the environment and interfere with their normal endocrine functions. They act like estrogen and exert their influence on the function of normal hormones in the organism, leading to the decline of reproductive functions in humans and animals, Genital tumors, decreased immunity, and cause a variety of physiological abnormalities. Most of the environmental hormones are released into the environment by human activities, which threaten the survival and reproduction of human beings. Now they have become another global environmental issue after the ozone depletion and the greenhouse effect. Currently, about 80,000 kinds of chemical substances are directly used by mankind around the world. Many harmful chemical substances enter the environment and cause environmental pollution during use, but not all of these harmful substances are environmental hormones.
