抗生素在地下水系统中的环境行为及生态效应研究进展

抗生素在环境中的残留已引起广泛关注。随着对地下水污染的报道日益增多,抗生素对地下水系统的潜在影响不容忽视。本文系统地阐述了地下水中抗生素的来源、污染水平及迁移转化规律,总结了抗生素对地下水微生物群落的影响以及抗生素诱导产生的抗性基因的潜在污染趋势。因地下水赋存隐蔽,一旦污染难以及时察觉,抗生素进入地下水系统后易长期残留。目前,针对抗生素及抗性基因在地下水系统中的环境行为及生态效应研究还十分有限,本文据此指出了当前形势下开展相关研究的必要性,并对今后的研究方向进行了展望。

Review on the Environmental Behavior and Ecological Effect of Antibiotics in Groundwater System

The residue of antibiotics in the environment has caused great concern. With the increasing report on groundwater pollution, the potential impact of antibiotics on the groundwater system is nonnegligible. In the present paper, the source, pollution situation, transport and transformation of antibiotics in groundwater are systematically reviewed. The effects of antibiotics on the microbial community in groundwater system, and the potential pollution trend of relative resistance genes induced by antibiotics are summarized. Due to the difficulty to be noticed, antibiotics entered into the underground water will exist for a long time. Currently, the research on the environmental behavior and ecological effects of antibiotics and relative resistance genes in groundwater system is quite limited. Accordingly, the significance of relative research and future directions are pointed out here.
