摘　　要：苯甲酮和苯并三唑类物质是应用广泛的紫外吸收剂,主要用于防止紫外辐射对人体皮肤和高分子材料的损害.随着温室效应和臭氧层破坏的加剧,紫外吸收剂的使用量日益增加,近年来,苯甲酮和苯并三唑类物质的内分泌干扰特性和对人体健康的潜在影响引起了广泛关注.本文系统地综述了苯甲酮及苯并三唑类紫外吸收剂的检测方法及环境残留的最新研究现状.目前,环境样品的预处理方法多采用固相萃取法,根据不同化合物极性大小,选择使用气相或液相色谱串联质谱进行检测.研究表明,苯甲酮和苯并三唑类物质在城市污水厂进出水和活性污泥中含量较高,地表水、地下水、土壤、底泥及生物体均能检测到此类物质的残留,土壤、底泥及生物样品中苯甲酮和苯并三唑类物质的浓度在ng·g^(-1)到μg·g^(-1)(干重)之间.同时,本文对苯甲酮及苯并三唑类物质在城市污水处理系统中的去除途径、多介质环境中的归趋、人体暴露及其风险评价等方面的研究趋势进行了展望.Benzophenones and benzotriazoles are widely used as ultraviolet absorbents to protect human skin and polymer material against UV radiation. Their applications have been increasing due to the intensification of the greenhouse effect and ozone depletion. In the past decade,benzophenones and benzotriazoles have attracted wide attention due to their endocrine disruption effects and potential threat to human health. This review mainly summarized the analytical methods and occurrence of benzophenones and benzotriazoles in environment. According to literature,most of environmental samples were treated by solid phase extraction,and benzophenones and benzotriazoles were analyzed by gas chromatography or liquid chromatography tandem mass spectrometry. The results indicated that concentrations of benzophenones and benzotriazoles were relatively high in municipal wastewater and sludge samples. Furthermore,they were also detected in surface water,soil,sediment and biota samples with the concentrations from ng·g-1to μg·g-1（ dry weight）.Finally,hot research topics（ the removal pathways in municipal wastewater treatment plants,environmental behaviors and fates, toxic effect, human exposure and risk assessment of benzophenones and benzotriazoles） were pointed out in future studies.
