摘　　要：综述了环境因素对微塑料性质的影响,讨论了微塑料对典型污染物的吸附行为,并对微塑料与污染物之间的吸附机理进行了探讨。微塑料的疏水性和粒径是原始塑料碎片吸附的主要影响因素,而对于老化的微塑料,氢键、亲水性和比表面积的增加会影响吸附行为。盐度和pH的影响总是通过改变微塑料和污染物的带电状态来影响吸附条件,从而引起竞争性吸附。这对于评估微塑料对从人类到整个环境的生物体所构成的潜在风险至关重要,并为今后微塑料对环境污染物的吸附富集行为研究提供理论依据。This article summarizes the impact of environmental factors on the properties of microplastics, further discusses the adsorption behavior of microplastics on typical pollutants and the adsorption mechanism between microplastics and pollutants.The hydrophobicity and particle size of the microplastics are the main factors affecting the adsorption of the original plastic fragments, while for the aging microplastics, the increase in hydrogen bonding, hydrophilicity and specific surface area will affect the adsorption behavior.The influence of salinity and pH always affects the adsorption conditions by changing the charged state of microplastics and pollutants, thereby causing competitive adsorption.This is essential for evaluating the potential risks of microplastics to organisms from humans to the entire environment, and hopes to provide a theoretical basis for future research on the adsorption and enrichment behavior of microplastics on environmental pollutants.
