摘　　要：随着二苯甲酮类紫外防晒剂的大量使用,其在水体中频繁检出.已有大量研究表明二苯甲酮类化合物在自然环境过程和人工水处理过程中可发生多种转化,其潜在的生态与健康风险值得关注.近年来,针对二苯甲酮类化合物的转化研究逐渐增多,发现其在不同条件下的转化行为复杂,且存在较大差异.本文从转化的化学反应机理出发,着重对二苯甲酮类化合物在氧化/消毒处理相关过程中的转化特征进行了梳理.结果表明二苯甲酮类化合物在氧化/消毒过程中主要发生氧化反应、取代反应、脱羧反应等,多数转化产物具有较高毒性,其潜在的生态与健康风险不容忽视.With the widespread use of benzophenone-type ultraviolet filters,they are frequently detected in aquatic environments.Numerous studies have indicated that benzophenone-type compounds can undergo various transformations in natural environmental processes and artificial water treatment processes,raising concerns about their potential ecological and health risks.In recent years,research on the transformation of benzophenone-type compounds has increased,revealing that their transformation behavior under different conditions is complex and exhibits significant variations.The present study reviews the transformation characteristics of benzophenone-type compounds in oxidation/disinfection-related processes from the perspective of chemical reaction mechanisms of these transformations.The results indicate that benzophenone-type compounds primarily undergo oxidation reactions,substitution reactions,decarboxylation reactions during oxidation/disinfection processes.Most of the transformation products exhibit relatively higher toxicity than the parent compounds,underscoring the importance of considering the potential ecological and health risks of benzophenone-type compounds.
