摘要
      由于抗生素的大规模生产和在临床应用和畜牧养殖中的广泛使用,抗生素在土壤和水中被频繁检测到,在土壤和水中,一系列非生物和生物过程可以共同决定其环境命运。抗生素在环境中的持续积累引起了人们的极大关注,因为残留的抗生素及其转化产物都可能对生态系统和人类健康构成潜在风险。本文在总结和分析近三年文献的基础上,综述了抗生素在土壤和水中的发生、吸附和降解过程。此外,还涉及与环境毒性、抗生素和TP引发的抗生素耐药性以及通过食物链的抗生素耐药性基因(ARGs)相关的风险。最后,提出了未来的研究前景,包括植物对抗生素和ARGs、TP的吸收及其与食物链相关的风险。
Abstract
Due to the mass production and extensive use in clinical application and livestock breeding, antibiotics have been detected frequently in soil and water, where a range of abiotic and biotic processes can jointly determine their environmental fate. The continuous accumulation of antibiotics in the environment has raised great concerns because both the residual antibiotics and their transformation products (TPs) could pose potential risks to the ecosystem and human health. Herein, based on summarizing and analyzing the literature in recent three years, we review the occurrence, adsorption and degradation processes of antibiotics in soil and water. Furthermore, the risks associated with environmental toxicity, antibiotic resistance triggered by both antibiotics and TPs, as well as antibiotic resistance genes (ARGs) through food chains are also addressed. Finally, future research perspectives are proposed including plant uptake of antibiotics and ARGs, TPs and their risks associated with food chains.
