摘要
微塑料(MP)已在大气、土壤和水中被检测到,并被定性为新出现的令人担忧的污染物。当暴露在这些环境中时,MPs会与化合物以及居住在这些生态系统中的(微生物)相互作用。本文综述了抗生素在MPs上吸附过程中的相互作用和影响因素,因为MPs和抗生素之间存在着不同的相互作用。介绍了MPs和抗生素抗性基因(ARGs)微生物宿主之间的相互作用,并讨论了可能形成质体抗性的重要因素。讨论了污水处理厂中MPs、抗生素和抗生素抗性细菌(ARB)以及ARGs的相互作用,旨在为更好地理解污水处理厂在将MP、抗生素和ARB/ARGs结合在一起方面的作用,以及进一步作为携带抗生素的MP和ARB/ARGs释放点提供一个视角。
Abstract
Microplastics (MPs) have been detected in atmosphere, soil, and water and have been characterized as contaminants of emerging concern. When exposed to these environments, MPs interact with the chemical compounds as well as the (micro)organisms inhabiting these ecosystems. This paper overviews the interactions and significant factors influencing the sorption process of antibiotics on MPs since distinct interactions are developed between MPs and antibiotics. The interplay between the MPs and the antibiotic resistant genes (ARGs) microbial hosts is presented and the important factors that may shape the plastisphere resistome are discussed. The interactions of MPs, antibiotics and antibiotic resistant bacteria (ARB) and ARGs in wastewater treatment plants (WWTPs) were discussed with the aim to provide a perspective for better understanding of the role of WWTPs in bringing together MPs, antibiotics and ARB/ARGs and further as release points of MPs carrying antibiotics, and ARB/ARGs.
