摘　　要：将持久性有毒物质(PTS)分为持久性有机污染物(POPs)和重金属两类.分别概述了这两类PTS在底泥中的来源与进入的方式;指出它们具有长期残留性、生物累积性、半挥发性和高毒性特征.重点分析了PTS在生态系统中的循环,对生物的生殖及器官的危害;介绍了监测POPs的4种化学仪器分析方法与生物分析方法,监测重金属的化学与生物分析方法;PTS的植物、微生物和物理化学修复技术,同时对PTS的未来研究进行了展望.The persistent toxic substances（PTS） are divided into persistent organic pollutants（POPs） and heavy metals.The soure of these PTSs and the ways for their entering the sediment were described.It was pointed out that these PTSs have the characteristics of semi-volatilized,high toxic,Long-term residual and biological accumulation.This article also reviewed the research status of the cycle of PTSs in an ecosystem,and PTS damage to the reproductive and organs of a living creature.Technique methods for chemical and biological detecting and analyzing PTSs were introduced.The technique of PTS physicochemical-remediation,bio-remediation and phytoremediation were also described.Finally,the research prospect of the PTS in sediment is anticipated.
