水环境中抗生素的分布、累积及生态毒理效应

抗生素持续大量使用带来的环境污染和潜在的生态风险已经引起广泛关注。总结了国内外相关研究成果,对水环境中抗生素的污染源及残留水平进行了分析,对抗生素在水生生物体内的累积规律给予了评述,同时对抗生素的生态毒理效应进行了探讨。鉴于我国水环境中抗生素的污染现状,建议未来加强环境相关浓度下抗生素在生物体内的分布与转化、食物链迁移与放大,以及多种抗生素联合效应等方面的研究。

Distribution, Accumulation and Eco-toxicological Effects of Antibiotics in Aquatic Environment

The environmental pollution and potential ecological risks caused by continued high rates of anti-biotics use had aroused widespread concerns. The relevant achievements of domestic and foreign researches were summarized for analysis of pollution sources and residue levels of antibiotics in waters. The accumulative rules of antibiotics in aquatic organisms were reviewed to discuss eco-toxicological effects of antibiotics. Considering China＇ pollution situation of antibiotics in water environment, it was made some suggestion that in the further research works should focus on key Subjects such as distribution and transformation of antibiotics in organisms, the transfer and amplification of antibiotics by food chains and the combined effects of multiple antibiotics in environ- mental relevant concentrations.
