摘　　要：邻苯二甲酸酯(PAEs)是一类普遍使用的化学工业品,并广泛存在于环境中。已有研究表明,PAEs环境内分泌干扰物,对人类和自然环境有非常大的危害。总结了PAEs在地表水中的分布和在水体中迁移转化的主要途径,如水解、光降解、与颗粒物(沉积物或悬浮颗粒物)的作用以及生物转化作用,并指出对它们进一步研究的重要性和今后主要的研究方向。Phthalate esters （PAEs） are harmful substances since they may disrupt human body＇s endocrine system＇s functions. Excessive use of phthalate esters in industrial applications, mainly as plasticizers, has raised serious concern about their adverse health effects and/or damage to the environment. This article presents an overview of distribution and transformation of PAEs in the aqueous environment, including the sources and major transformation mechanisms： hydrolysis, photodegradation, adsorption, and biodegradation. There is a need for more research on transformation of PAEs and the intermediate products, contribution of individual degradation mechanisms to the observed removal, and effects of colloidal matters on adsorption of PAEs in lab and natural waters.
