中文摘要：

多环芳烃（Polycyclic Aromatic Hydrocarbon,PAHs）是水体中常见的有机污染物,其迁移转化途径包括化学吸附、挥发、光分解和化学降解等,但生物富集与降解是水体中PAHs去除的主要环境过程。结合国内外研究动态,重点探讨了藻类对PAHs的降解机理和环境因子对降解过程的影响,同时对日后研究方向进行了展望,指出今后应加强藻类对持久性有机污染物的吸附模型、降解过程中的基因调控机制等方面的研究。

英文摘要：

Polycyclic Aromatic Hydrocarbons are common persistent organ ic pollutants in water. Their migration and transformation pathway included chemisorption, volatilization, photolysis, chemical degradation and so on. Among them, the main removal means of PAHs in water are biocondensation and degradation. This paper combined the domestic and foreign research dynamics, introduced the enrichment and degradation characteristics, mechanism and influence factors, and then focused on the PAHs degradation mechanism and the effects of environmental factors to PAHs degradation efficiency.Meanwhile this text looked to the future research directions and pointed out some research direction need to be strengthened,such as the organic pollutant adsorption model and gene regulation mechanism in pollutant degradation process.
