药物和个人护理品的水环境光化学转化动力学研究

Photochemical Transformation Kinetics of Pharmaceuticals and Personal Care Products in Aquatic Environment

药物和个人护理品(PPCPs)是水环境中经常检出的一类新型微量有机污染物,因其具有潜在的健康和生态风险而备受关注。光化学转化是PPCPs在表层水体中的重要降解途径,且影响其环境归趋和生态风险。本文综述了PPCPs的直接光解和间接光解动力学过程,探讨了pH和水中共存组分对PPCPs光解动力学的影响,对PPCPs水环境光解动力学的研究方向进行了展望。

Pharmaceuticals and personal care products （PPCPs） as emerging micro- pollutants are frequently detected in aquatic environment. They are of increasing concern due to their potential healthy and ecological risks. Photochemical transformation of PPCPs is an important photo - degradation pathway in surface water, which can im- pact their environment fate and ecological risks. In this paper, both direct photolytic kinetics and indirect photolytic kinetics for PPCPs were reviewed. The effects of pH and concomitants and water constituents on the photolytic ki- netics of PPCPs were discussed. Finally, further studies on the photolytic kinetics of PPCPs were proposed.
