摘　　要：近年来,药物和个人护理品(pharmaceuticals and personal care products,PPCPs)作为一类新兴环境污染物,在多种环境介质中频繁检出,并对生态系统和人类健康造成潜在风险,日益引起广泛关注。植物修复技术以植物为基础,通过太阳能驱动的生物过程去除污染物,具有能耗低、成本低、环境友好等独特优势,常用于水体污染修复。浮萍作为植物修复中常用模式生物,体型微小、结构简单、无性繁殖速度快,且具有较强的适应能力和较好的污水修复能力。本文针对浮萍在PPCPs环境污染修复中的研究进展和应用现状进行综述,重点总结了浮萍对PPCPs的去除机制,包括生物吸附、生物吸收和生物降解等,并对未来的研究方向提出展望,以期为浮萍在PPCPs修复中的应用提供科学依据。As a typical class of emerging contaminants,pharmaceuticals and personal care products(PPCPs)have attracted widespread attention,due to their frequently detection in various environmental matrices,and their potential risks to ecological system and human health.Based on plants,phytoremediation is applied to remove pollutants with biological processes driven by solar-power.Due to its unique advantages of low energy consumption,low cost and environmental friendliness,phytoremediation is commonly used for wastewater bioremediation.As a model organism for phytoremediation,duckweed are the smallest flowering plants with simple structure and easy to accumulate biomass with rapid asexual propagation.Besides,duckweed exhibit strong adaptation to various environments and well performance in wastewater bioremediation.Herein,we reviewed the research advances on the application of duckweed in PPCPs bioremediation,focusing on the bio-adsorption,bio-uptake and biodegradation of PPCPs by duckweed.Then we presented some research challenges and proposed future directions of duckweed research.This systematic review provides scientific basis for the practical application of duckweed in bioremediation of PPCPs in environment.
