Antibiotics (ATs) are ubiquitously detected in natural waters worldwide, and their tendency to co-migrate with microplastics (MPs) post-adsorption leads to heightened environmental risk. Research on the adsorption of ATs on MPs and their subsequent effects on the environmental risks is gaining significant attention globally. This adsorption process predominantly occurs through hydrophobic forces, hydrogen bonds, and electrostatic interactions and is influenced by various environmental factors. The interaction between MPs and ATs exhibited varying degrees of efficiency across different pH levels and ionic strengths. Furthermore, this paper outlines the environmental risks associated with the co-presence of MPs and ATs in aquatic environments, emphasizing the potential effect of MPs on the distribution of antibiotic resistance genes (ARGs) and related environmental risks. The potential hazards posed by MPs and ATs in aquatic systems warrant serious consideration. Future research should concentrate on the adsorption of ATs/ARGs on MPs under real environmental conditions, horizontal gene transfer on MPs, as well as biofilm formation and agglomeration behavior on MPs that needs to be emphasized.
抗生素（ATs）在世界范围内的自然水中普遍存在，它们在吸附后与微塑料（MPs）共同迁移的趋势导致了更高的环境风险。目前，全球对 ATs 在 MPs 上的吸附及其对环境风险的后续影响的研究受到了极大关注。这种吸附过程主要通过疏水作用力、氢键和静电相互作用发生，并受到各种环境因素的影响。MPs 和 ATs 之间的相互作用在不同的 pH 值和离子强度下表现出不同的效率。此外，本文概述了 MPs 和 ATs 在水生环境中共存所带来的环境风险，强调了 MPs 对抗生素耐药基因（ARGs）分布和相关环境风险的潜在影响。MPs 和 ATs 在水生系统中带来的潜在危害值得认真考虑。未来的研究应集中在实际环境条件下 MPs 上 ATs/ARGs 的吸附、MPs 上的水平基因转移，以及需要强调的 MPs 上生物膜形成和聚集行为。
