微塑料在海洋微食物环的富集与循环作用

Effects of Microplastics on Enrichmentand Circulation in Marine Microbial Loop

本文对微塑料(Microplastics,MPs)在海洋微食物环的循环、富集以及对生物的影响进行了概述,突出了微食物环在微塑料迁移转化中的重要作用,为正确理解微塑料在海洋环境中的归趋提供了理论依据。本文首先介绍了微塑料基本特性与研究现状,并对世界部分海区中微塑料的分布情况进行阐述。其次,叙述了微塑料在沿海洋微食物环中的循环和富集作用,特别是对微塑料单独作用及其与污染物联合作用时对生物体的毒害作用进行了讨论。

In this paper,we summarize the cycle,enrichment and biological impact of microplastics(MPs)in marine Microbial loop,highlight the important role of microplastics in the migration and transformation of microplastics,and provide a theoretical basis for correctly understanding the fate of microplastics in the marine environment.This article first introduces the basic situation and research status of microplastics,and summarizes the distribution of microplastics in the sea areas of the world.Secondly,the circulation and enrichment of microplastics along the marine Microbial loop are preliminarily introduced,and the toxic effects of microplastics on organisms when acting alone and in combination with pollutants are discussed.
