Micro(nano)plastics have become a new type of pollutant with the characteristic of being difficult to degrade in the environment,which can exist in water,sediment,soil and other environmental media for a long time and endanger the ecological stability.Studies on the distribution,origins,and ecotoxicity effects of micro(nano)plastics in domestic surface water environments have found that the sources of micro(nano)plastics in surface water environments are diverse,with direct sources mainly including personal care products,industrial and agricultural production,improper disposal of various types of waste,and indirect sources such as sewage discharge from wastewater treatment plants,surface runoff,and weathering degradation of primary plastics.The ecotoxicological composition of micro(nano)plastics is complex,not only causing biochemical stress on organisms themselves but also easily forming complex pollutants with other contaminants,producing interactive effects on aquatic organisms.Therefore,the management of micro(nano)plastic pollution in surface water environment is urgent.It can provide theoretical references for the prevention and control of micro(nano)plastic pollution in surface water environment and ecological risk research.
