摘要
微塑料和纳米塑料逐渐成为人们研究探讨的热点.在自然条件下,直径小于5 mm的塑料碎片(微塑料)可以进一步被降解为纳米级别(纳米塑料).微塑料和纳米塑料的粒径较小,很容易随着食物链富集,从而进入生物体内,甚至存在于人体内.微(纳米)塑料的化学性质稳定,可以在环境中长期存在,对环境造成一定的不良影响.本文主要综述了微(纳米)塑料对淡水环境的影响,包括微(纳米)塑料的来源和分布情况,微(纳米)塑料对淡水生物生长发育、繁殖、行为以及进入淡水生物体内或进一步进入生物体内各组织中对机体产生的毒性效应.
In recent years,microplastics and nanoplastics have gradually become the focus of people s research.Under natural conditions,microplastics were plastic fragments less than 5 mm in diameter and could be further degraded to nanoscale(nanoplastics).Micro-plastics and nano-plastics were small particle sizes and easily enriched in the food chain to enter the organism and even in the human body.Moreover,they were chemically stable and could exist in the environment for a long time,which had certain adverse effects on the environment.This article reviews the effects of micro(nano)plastics on the freshwater environment,including the origin and distribution of microplastics.The toxic effects of micro(nano)plastics on the growth,reproduction,behaviour and entry into freshwater organisms or tissues of freshwater organisms.
