环境中有机紫外防晒剂残留及其生态毒性研究进展

有机紫外防晒剂被广泛添加在个人护理品中,随着日常使用源源不断地进入环境中,成为一类新兴污染物。环境介质中有机紫外防晒剂的检测及其生态毒理是目前的研究热点。概述了个人护理品中常用的有机紫外防晒剂,总结了有机紫外防晒剂在各类地表水、沉积物和生物体等不同介质中的浓度水平,详细分析了有机紫外防晒剂对鱼类的内分泌干扰效应和对水生无脊椎动物的急性毒性,为今后深入研究和科学评价这类新兴污染物提供重要参考。

A Review on the Occurrence and Ecotoxicity of Organic UV Filters in Environment

A large number of UV filters extensively occurred in personal care products (PCPs) daily consumed by people, which are released into environment. They become a kind of emerging pollutants. The occurrences of UV filters in environment and their ecotoxicology effects have been widely concerned. This paper reviewed the research development on the occurrences and ecotoxicity studies of the organic UV filters. First, a general introduction of organic UV filters in personal care products was summarized. Second, the environmental concentrations reported in different mediums such as surface water, sediments and biota around the world were described. Finally, the ecotoxicity effects of organic UV filters in the aquatic environment were discussed, especially for the endocrine disruption effects on fish and the acute toxicity effects on invertebrates. This review provides the useful references and some research directions for future studies. The information is helpful for the risk assessments of these new emerging contaminants.
