微塑料（microplastics, MPs）和抗生素作为新兴污染物，经常在水环境中能被同时检测到，并且水环境中的抗生素也经常在MPs表面被发现。MPs可以通过表面吸附和迁移，吸收、聚集并携带水环境中的各类有机污染物而受到广泛关注。与原始MPs相比，老化后的MPs因粒径变小、比表面积增大，从而吸附位点增多，而具有更强的吸附能力。主要从MPs的环境老化方式、老化后MPs对水环境中各类抗生素的吸附行为展开了综述，总结了老化MPs的老化方法及吸附抗生素的影响因素及吸附机理，并对MPs老化问题及对抗生素的吸附影响提出展望。

As emerging contaminants, microplastics (MPs) and antibiotics are often detected simultaneously in the water environment, and antibiotics in the water environment are often found on the surface of MPs. MPs can absorb, collect and carry various organic pollutants in water environment through surface adsorption and migration. Compared with the original MPs, the aging MPs has stronger adsorption capacity due to smaller particle size, larger specific surface area, and more adsorption sites. The environmental aging mode of MPs and the adsorption behavior of MPs on various antibiotics in water environment after aging were mainly reviewed, The aging method of MPs and the influencing factors and adsorption mechanism of antibiotics was summarized, and prospects for the aging problem of MPs and the effect on antibiotic adsorption was put forward.
