摘要
持久性有机污染物严重危害自然环境和生态健康,二恶英是地球上毒性危害最大的一类持久性有机污染物。近年来,二恶英的毒性危害、致毒机理及在自然环境介质中分布等科学问题一直是人们研究的焦点。本文尝试从二恶英的毒性当量、致毒机理和对人类的毒性效应三个方面阐述二恶英的毒性危害,并初步总结国内土壤和沉积物中二恶英的研究现状与进展,最后对二恶英在土壤和沉积物中的行为及毒性病理学等研究领域进行了展望。
Persistent organic pollutants( POPs) have shown serious harmful effects on natural and ecological environments. Dioxins are among the most toxic POPs,therefore,the toxicology and the risk of dioxins as well as the distribution of dioxins in environmental and human samples have drawn increasing research attentions recent years. This review paper generally summarized the relevant literatures on toxic equivalents of dioxins,toxication mechanisms of dioxins and toxic risks of dioxins to human,and carefully combined current researches on dioxins in soils and sediments of China,and then presented our suggests on future studies.
