中文摘要：

多溴联苯醚（PBDEs）是一类全球性的有机污染物，近年来由于其持久性、毒性和潜在的生物蓄积性而备受关注。光化学降解是环境中多溴联苯醚的重要归趋之一。本文综述了有机溶剂、水相和固相等不同介质中人工紫外光源和太阳光下PBDEs的光降解研究成果，不仅介绍了光源、反应介质、溴取代数目和取代型式对PBDEs光解速率和光解产物的影响，也包括了基于PBDEs光解的定量结构一性质关系，并展望了环境中PBDEs光化学行为的研究前景。

英文摘要：

Polybrominated diphenyl ethers （PBDEs） are considered as a group of global organic pollutants, and have recently received increasing concerns due to their persistence, toxicity and potential for bioaccumulation. Photochemical degradation is one of the important fates for PBDEs in natural environment. In this paper, recent developments about the photochemical degradation of PBDEs under artificial UV light or sunlight in different matrices are reviewed, such as organic solvents, water and solid. Not only the influences of light sources, reaction matrices, number of bromine substituents and substitution pattern on the photolysis rates and photoproducts of PBDEs are introduced, but also the quantitative structure-property relationships based on the photochemical degradation of PBDEs are referred. In addition, the research prospects about the photochemical behavior of PBDEs in the environment are proposed.
