医药品与个人护理品(PPCPs)作为一类大量使用和具有潜在生理效应的"新型"化学物质,近年来受到科学界和社会的普遍关注。环境中的PPCPs主要来源于污水处理厂不完全处理导致的排放和人类农业或畜牧业活动的直接排放。PPCPs连续性输入使得它们在环境中呈现出一种"持久"存在的状态,进而可能对生态系统和人类健康产生危害。本文综述了PPCPs的环境分析方法研究进展、在水处理过程中的行为变化和目前在各种不同环境中的浓度水平,介绍了当前PPCPs的毒性研究结果及初步的风险评价工作,并对PPCPs类物质未来的研究方向进行了展望。
There is increasing concern about pharmaceuticals and personal care products (PPCPs) during the last decade due to their environmental occurrence and potential physiological effects. These compounds can be continually discharged into the environment primarily via untreated and treated sewage since current wastewater treatment plant can not completely remove them. This results in chronic low concentration exposure of aquatic organisms by PPCPs, which potentially hazard the ecological system and human health. This paper reviews current studies on the environmental analytical methods, occurrence, fates in the wastewater treatment process, potential ecological impacts, and preliminary risk assessment of PPCPs.
