当今,新化学物质不断产生,随之对环境的污染日趋严重,对生殖健康的危害也日益增加。环境中的二噁英(dioxin)是氯代含氧三环芳烃类化合物,无任何实际用途。二噁英是一种毒性极强的特殊有机化合物,包括多氯代二苯并二噁英(PCDDs)、多氯代二苯呋喃(PCDFs)和多氯代联苯(PCBs)等。其中以2、3、7、8位氯取代的异构体毒性最大,称为TCDD(2、3、7、8-tetrachloro-dibenzo-para-dioxin),是目前世界上已知的毒性最强的人类一级致癌物。现就二噁英的环境污染,在体内的分布、对生殖健康的危害及其预防分述
Today, new chemical substances are constantly produced, along with the increasingly serious pollution of the environment and the increasing harm to reproductive health. Dioxin in the environment is a chlorinated oxygenated tricyclic aromatic compound, without any practical use. Dioxin is a very toxic and unusual organic compound, including PCDDs, PCDFs and PCBs. The 2,3,7,8-tetrachloro-dibenzo-para-dioxin (TCDD) is the most toxic one which is substituted by chlorine at 2,3,7,8, which is the most toxic known in the world A human carcinogen. Now on the environmental pollution of dioxin, the distribution in the body, the harm to reproductive health and its prevention
