Current situation of antibiotic contamination in China and the effect on plankton.

In recent years, antibiotics have been continuously detected in waterbodies and thus has become an environmental problem, especially in China. However, current knowledge regarding the ecological hazards of antibiotics is mainly focusing on the induction of resistance in pathogenic microorganisms, treating antibiotic contamination as a public safety problem that seriously endangers human health, but relatively ignores its potential risk to aquatic organisms. As an important component of aquatic ecosystems, plankton play an important role in maintaining the stability of aquatic ecosystems. Meanwhile, plankton are very sensitive to environmental changes. Therefore, understanding the impact of antibiotics on plankton is the basis for assessing their ecological risk. To this end, we summarized current status of antibiotic contamination in China's aquatic environments, and analyzed the impacts of antibiotics on planktons. In addition to using metabolomics technology to reveal the negative impacts of antibiotics at the individual level, monitoring of antibiotics and plankton communities in the field needs to be strengthened in the future. 近年来,抗生素在水体中不断被检出,已经成为重要的环境污染问题,中国抗生素污染问题尤为严重。然而,当前人们对抗生素生态危害的认知主要集中在诱导病原微生物产生抗药性上,将抗生素污染视作危害人类健康的公共安全问题,却相对忽视了它对水生生物的潜在风险。浮游生物作为水生态系统的重要组成成分,对维持水生态系统稳定具有重要作用;同时,浮游生物对环境变化非常敏感。了解抗生素对浮游生物的影响是评估其生态风险的基础。为此,本文归纳了当前国内水环境中抗生素污染现状,分析了抗生素对浮游生物的影响。今后,除了利用代谢组学技术进一步揭示抗生素对浮游生物个体危害的机制外,还需加强野外抗生素与浮游生物群落的监测。.
