药物及个人护理品在水中光解的研究进展

A critical review of photodegradation of PPCPs in environment

近年来,药品及个人护理品(PPCPs)作为一类新型环境污染物,由于其对人类和生态系统潜在的影响而受到广泛关注.由于PPCPs一般被设计成具有一定生理作用的结构,因而具有生物难降解性.在天然水体中,光降解被认为是PPCPs环境归趋的主要机制.对近年来PPCPs光降解的研究进展进行了综述,重点介绍了直接光解和间接光解的机理及其影响因素,并由此提出了本领域今后的研究方向.

In recently years ,pharmaceuticals and personal care products (PPCPs ) have received increasing attention as an emerging class of environmental pollutants due to their potential haz-ardous effects on human and the aquatic ecosystem .Because PPCPs have been designed to have a specific physiological effect on human or animals ,many of them have been presumed to resist to biodegradation .In surface waters ,photodegradation was considered as one of the potential signif-icant depletion mechanisms of PPCPs .Emphasizing on the mechanism of direct and indirect pho-todegradation and their influence factors ,this paper reviewed the recently research progress of photodegradation of PPCPs .In addition ,further research orientation was also proposed for this field .
