【摘要】 微塑料（MPs）是一种新型污染物，可在河流、湖泊和水库中检出，治理难度较大。文章从不同类型MPs老化后的形貌、结晶度、比表面积等变化，介绍了环境中MPs的老化特性。针对不同类型MPs吸附污染物（重金属、有机污染物）的机制（静电作用、范德华力、氢键、疏水作用和π-π相互作用）及影响因素进行了综述。文章指出，未来解决MPs污染相关问题的根源在于控制污染源，减少难降解塑料的生产与使用，开发易降解和可替代的绿色环保产品，加强塑料垃圾的回收处置。更多还原

【Abstract】 Microplastics(MPs) are a new type of pollutant,which are detected in rivers,lakes and reservoirs,and are difficult to control.The aging characteristics of MPs in the environment are introduced from the changes of morphology,crystallinity and specific surface area of different types of MPs after aging.The mechanisms(electrostatic interaction,van der Waals force,hydrogen bonding,hydrophobic interaction and π-π interaction) and influencing factors of different types of MPs adsorbing pollutants(heavy metals and organic pollutants) are reviewed.It is pointed out that the root of solving MPs pollution related problems in the future is to control pollution sources,reduce the production and use of refractory plastics,develop easily degradable and alternative green environmental protection products,and strengthen the recycling and disposal of plastic waste.更多还原
