水体中微塑料的重金属吸附行为及其对水生生物的毒性效应

Adsorption Behavior of Microplastics for Heavy Metals in Water and Its Toxic Effects on Aquatic Organisms

作为一种新兴污染物,微塑料已经广泛分布于海洋和淡水系统中.同时,微塑料作为重金属等污染物的重要载体,对水生态健康造成潜在威胁.为了探究水体中微塑料对重金属的吸附行为以及该行为对水生生物的毒性效应,综合分析了近年来国内外相关研究进展,从水体中微塑料的种类、微塑料的分布、微塑料对重金属的吸附行为和机理、吸附重金属的微塑料对水生生物的毒性效应等几个方面进行了归纳总结,为微塑料研究、防治提供更加系统、坚实的理论依据.

As a novel pollutant,microplastics,widely distributed in the marine and freshwater systems,play important roles as vectors for heavy metals,which pose potential risks in the aquatic environment.To explore its adsorption behavior for heavy metals in water and its toxic effects on aquatic organisms,this paper comprehensively analyzed the relevant public researches in recent years,including the classification and distribution of microplastics,the adsorption behavior and mechanism of heavy metals by microplastics,and the toxic effects of heavy metals adsorbed by heavy metals on aquatic organisms.It provides some systematic reference for the prevention and control of micro plastic pollution in the future.
