摘要:紫外吸收剂大量用于工业材料和个人护理品中，近年来在水体中不断被检出，同时由于其高度亲脂性，易在底泥和水生生物体内富集，产生潜在的毒性效应，已成为一类新型污染物。本文综述了紫外吸收剂在湖泊环境中的分布和生物富集效应，重点分析了二苯甲酮类等典型紫外吸收剂对底栖动物的药物代谢系统、抗氧化系统及其生长发育的影响及其毒性作用机制，并对未来该领域的研究进行了展望。

Abstract:UV absorbers are high production volume compounds that are widely used in industrial materials and personal care products. Due to their ubiquitous application and persistence, UV absorbers have been frequently detected in aquatic ecosystems and become emerging pollutants. For their high lipophicity, UV absorbers can be adsorbed in sediments and bioaccumulated in benthic animals, and thus show their potential toxicity. In this review, the distribution of UV absorbers in the lake environment and their bioaccumulation in benthic animals were summarized. Futhermore, the toxicological effects of UV absorbers (e.g. diphenylmethanones) on chemical metabolism, oxidative stress as well as growth and development of aquatic organisms were highlighted. Based on these, limitations of current toxicological research on UV absorbers were pointed out and suggestions were accordingly proposed for future studies of these chemicals in aquatic toxicology.
