Antibiotics are widely used as drugs and enter water bodies through various routes, leading to environmental pollution. As a green in-situ remediation technology, phytoremediation has been proven to be highly effective in removing antibiotics present in the aqueous phase. However, these data are distributed in various studies and lack systematic analysis, which could provide a more comprehensive understanding of the current status and trends in the research field. Based on this, a meta-analysis was conducted from three perspectives in this study: the factors influencing antibiotics removal by phytoremediation, the effect of antibiotics on plant physiological indexes, and the accumulation and translocation of antibiotics in plants. The results showed that plants have a significant effect on antibiotics removal, which is influenced by plant species, running time, biomass, antibiotic types and antibiotic concentration. Although some physiological indexes of plants changed under stress from high antibiotic concentrations, most plant species demonstrated resistance to antibiotic concentrations below 100 μgL. Additionally, the amount of antibiotics accumulated in plants was extremely little, so the risk of secondary pollution was minimal during phytoremediation. The results of this study reveal the main factors influencing antibiotics removal by phytoremediation and plant physiological responses to antibiotics, providing a reference for improving the rational application of phytoremediation for antibiotics removal. In addition, it will provide concepts and directions for improving the efficiency of sustainable and environmentally friendly remediation methods for treating antibiotic pollution.
抗生素被广泛用作药物，并通过各种途径进入水体，导致环境污染。植物修复作为一种绿色原位修复技术，已被证明在去除水相中存在的抗生素方面非常有效。然而，这些数据分布在各种研究中，缺乏系统的分析，这可能会提供对研究领域现状和趋势的更全面的了解。基于此，本研究从植物修复去除抗生素的影响因素、抗生素对植物生理指标的影响以及抗生素在植物中的积累和迁移三个角度进行了荟萃分析。结果表明，植物对抗生素的去除有显著影响，这受到植物种类、运行时间、生物量、抗生素类型和抗生素浓度的影响。尽管一些植物在高抗生素浓度的胁迫下某些生理指标发生了变化，但大多数植物物种对浓度低于 100 μgL 的抗生素表现出抗性。此外，植物积累的抗生素数量非常少，因此在植物修复过程中二次污染的风险最小。本研究的结果揭示了影响植物修复去除抗生素的主要因素和植物对抗生素的生理响应，为提高植物修复去除抗生素的合理性提供了参考。此外，它将为提高可持续和环保修复方法处理抗生素污染的效率提供概念和方向。
