天然水体中微塑料的来源、分布及毒性效应

天然水体中的微塑料具有粒径小、比表面积大等特点,以及一定的化学毒性,严重威胁着生态环境和人类健康。概述了天然水体中微塑料的来源及分布,重点阐述了天然水体中微塑料的化学毒性及其毒性效应,并对微塑料毒性效应的未来研究方向进行了展望,为进一步促进微塑料的风险评估和科学治理研究提供参考。

Characterized by small particle size and large specific surface area,microplastics in aquatic systems threaten the ecosystem and human health severely with their particular chemical toxicity.This thesis summarizes the source and distribution of microplastics,focuses on the chemical toxicity and toxic effects of microplastics in aquatic systems,and prospects the future research direction of the toxicity effects of microplastics,which provides support for the risk assessment and scientific management of microplastics.
