摘　　要：抗生素在环境中的暴露及其生态风险已引起了广泛关注。微藻作为水生态系统的初级生产者,对于维持生态系统的平衡和稳定具有重要作用。本文综述了抗生素对微藻的生长、超微结构、光合系统、抗氧化系统和基因表达的毒性效应;分析总结了微藻对抗生素的消除作用和机制,以及光降解、生物吸附、生物富集和生物降解在抗生素消除过程中的贡献;初步探讨了抗生素的生态毒性效应与微藻对其消除作用之间的交互作用;最后指出未来应加强长期暴露下低浓度抗生素的联合毒性效应和微藻的生物降解机制方面的研究,为抗生素的生态风险的准确评估提供科学依据。The occurrence and ecological risk of antibiotics in the environment have attracted global concern.As the primary producer in the aquatic ecosystem,microalgae play an important role in maintaining the stability and balance of the ecosystem.In this paper,the ecotoxicological effect of antibiotics on the growth,ultrastructure,photosynthetic system,antioxidant system and related gene expression of microalgae was reviewed.The removal efficiency and mechanism of antibiotics by microalgae were summarized,and the contributions of photodegradation,biosorption,bioaccumulation and biodegradation in the removal of antibiotics were analyzed.The interaction effects between the ecotoxicity of antibiotics and their removal by microalgae were preliminarily explored.At last,it was pointed out that the research about the combined ecotoxicology effects of low concentration of antibiotics under long-term exposure,and the biodegradation mechanisms of antibiotics by microalgae should also be strengthened for future research.This paper provides a scientific basis for the accurate assessment of the ecological risk of antibiotics.
