摘　　要：二噁英类化合物是一类对生态和人类健康构成极大威胁的持久性有毒污染物。二噁英类化合物广泛分布在大气、土壤、水体、沉积物和生物体中,并可在生物体中富集放大,最后通过食物链作用于人体,对人类健康产生严重危害。本文介绍了最近10年来二噁英类化合物的生态和健康风险方面的研究工作,并提出了加强我国二噁英类化合物的生态/健康风险评估研究的几点建议。Polychlorinated dibenzo-p-dioxins （PCDDs）, dibenzo-p-dioxins （PCDFs） and dioxin-like coplanar PCBs are well-known persistent contaminants and represent the most toxic categories, which pose serious risks to ecosystem and human beings health. Due to their physical and chemical characteristics, PCDDs, PCDFs and Co-PCBs are found in almost every environmental compartment, such as ambient air, soil, water, sediments and biological matrices of humans and of various plants and animals. PCDDs, PCDFs and Co-PCBs together with their lipophilic properties lead to their accumulation in the food-chain in proportional and cause considerable problems of human health. This paper reviews research reports about ecological and human health risks during last decade all over the world. Suggestions in ecological and human health risk assessments of PCDDs, PCDFs and Co-PCBs in China are proposed.
