摘　　要：环境中与日俱增的有机污染物严重危害着生态环境和人体健康.先前研究往往忽视了有机污染物分子团簇(molecular cluster of organic contaminants,MCOCs)的影响,而MCOCs的形成可能改变有机污染物的理化特性,进而影响其环境行为和归趋.分子结构特性及环境条件决定了有机污染物的赋存状态(分子态、离子态、团簇态和沉淀态),也进一步决定了其环境行为和风险.比如,MCOCs相较于其它赋存状态可能更有利于其被快速吸附,但也可能由于其尺寸较大而限制了在孔隙内的活动.文章综述了决定有机污染物(多环芳烃、邻苯二甲酸酯、其它有机污染物)赋存状态的因素以及它们的环境行为和环境效应,并总结了MCOCs形成的普遍性和显著性,着重强调了它们的环境行为、效应及潜在的环境风险,旨在为有机污染物的环境行为和效应研究以及其污染控制策略的形成提供理论支撑.The increasing number of organic contaminants in the environment seriously harms the ecological environment and human health.Previous studies have often neglected the effect of molecular clusters of organic contaminants(MCOCs),which may alter the physicochemical properties of organic contaminants and thus affect their environmental behavior and fate.The molecular structure properties and environmental conditions determine the states of organic contaminants(molecular,ionic,cluster and precipitation states),which further determine their environmental behavior and risk.For example,clusters may be more beneficial to their rapid adsorption than other occurrences,but large size may also limit their activity within the pores.This paper reviews the factors that determine the occurrence of organic contaminants(polycyclic aromatic hydrocarbons,phthalates,and other organic pollutants)and their environmental behaviors and fates.Accordingly,the universality and significance of MCOCs formation were summarized,and their environmental behaviors,fates,and potential environmental risks were emphasized.This paper aims to provide theoretical support for the research on organic contaminants'environmental behavior and fates and their pollution control.
