摘要
二英被称为是人类未曾遇到的最具毒性,严重威胁人类健康,能引发多种疾病的环境污染物.其存量极微,危害极大,已经引起了发达国家的普遍关注.本文在介绍二英性质、种类、来源等基础上指出了对生物体的毒害及毒性评价方法,分析了二英在大气、水、土壤、污泥、食品、人体中的污染积累,提出了今后的研究的主要问题和方向.
Dioxins are the most toxic substances that human beings have ever encountered in the world. The public health is seriously threatened by these substances.In this report, based on the introduction of the toxicity,categories and sources of dioxins , pollutiontoxicity for human and methods of estimation were reviewed. Furthermore, the pollution of dioxins in atmosphere, soil, sludge, food stuff and body were analyzed, and the key research problems and the directions of study for thefuture were indicated.
