海洋微塑料污染的生物效应研究进展

微塑料是粒径小于5mm的各类塑料碎片的总称。在环境领域中,微塑料污染已经成为人们的关注热点。近年来,海洋环境中微塑料污染日益严峻,其引发的生物与环境问题也备受关注。本文系统总结了海洋微塑料污染的生物效应研究进展,介绍了微塑料的定义、来源、分类、分布特征等研究现状,分析了微塑料对海洋环境中海水水质和沉积环境的影响,综述了微塑料对海洋生物的毒性效应,并基于研究进展提出了未来需关注的研究方向,以期为海洋微塑料对环境与生物的影响研究提供借鉴和参考。

Research progress on the biological effects of marine microplastic pollution

Microplastics is a general term for all kinds of plastic fragments with particle size less than 5 mm.In the field of environment, microplastic pollution has become a hot topic.In recent years, the pollution of microplastics in marine environment is becoming more and more serious, and the biological and environmental problems caused by it have also attracted much attention.In this paper, the research progress on biological effects of marine microplastics pollution is reviewed. The definition, source, classification and distribution characteristics of microplastics are introduced. The effects of microplastics on marine water quality and sedimentary environment are analyzed. The toxic effects of microplastics on marine organisms are summarized. Based on the research progress, the future research directions are proposed It is expected to provide reference for the study of the impact of marine microplastics on environment and biology.
