Abstract: The research progress of separation and analysis methods of Microplastics(MPs), including mechanical filtration, chemical treatment, colloidal coprecipitation, density gradient centrifugation and optical/fluorescence/Raman analysis, was reviewed. Their advantages, disadvantages and application range- DOI:10.3969/j.issn.1000-1565.2024.01.011微塑料的测定方法以及对水生生物的生态毒理效应崔铁峰1,2,张杰1,卢灿然1,王宏伟1,叶晔3(1.河北大学 生命科学学院 生命科学与绿色发展研究院,河北 保定 071002;2.华东师范大学 河口海岸科学研究院,河口海岸国家重点实验室,上海 200241;3.中日友好环境保护中心 科技中心,北京 100029)摘 要:综述了当前微塑料(microplastics, MPs)分离和分析方法的研究进展, 包括机械过滤、化学处理、胶体共沉淀、密度梯度离心和光学/荧光/拉曼分析等方法, 同时介绍了它们的优缺点和适用范围, 为微塑料污染的检测、监测和评估提供了参考.概述了MPs对水生生物的毒性效应:MPs在被水生生物摄入的过程中会对生物体的消化道造成物理损伤, 同时MPs的摄入会增加饱腹感, 影响水生生物对食物的消化吸收;MPs的摄入还会使水生生物肠道中的微生物群落组成和多样性发生改变;MPs暴露会引起水生生物基因的改变,还会诱发水生生物的氧化应激反应, 并干扰其脂质和能量代谢.MPs对消化系统的影响及对肠道微生物平衡的破坏可能是生物体脂质和能量代谢相关基因改变的原因之一.MPs可以吸附和富集其他物质, 从而对生物产生更严重的联合毒理效应.MPs对生物体消化道的物理损伤及其在生物体内的积累和扩散可能是引起氧化应激反应和免疫反应的主要原因.不仅对水生生物, MPs对人类的健康风险也引起人们对其潜在影响的关注.关键词:微塑料;水生生物;生态毒理效应中图分类号:Q89 文献标志码:A 文章编号:1000-1565(2024)01-0084-08Methods for determination of microplastics and their ecotoxicological effects on aquatic organismsCUI Tiefeng1, 2, ZHANG Jie1, LU Canran1, WANG Hongwei1, YE Ye3(1.

The toxic effects of MPs on aquatic organisms were also reviewed: MPs could cause physical damage to the digestive tract of aquatic organisms during ingestion, while the ingestion of MPs could increase satiety and affect the digestion and absorption of food by aquatic organisms; the ingestion of MPs could also alter the composition and diversity of microbial communities in the gut of aquatic organisms; MPs exposure could cause genetic alterations in aquatic organisms. The effects of MPs on the digestive system and the disruption of gut microbial homeostasis may be one of the causes of genetic alterations related to lipid and energy metabolism in organisms; the physical damage to the digestive tract and the accumulation and spread of MPs in organisms may be the main cause of oxidative stress and immune responses. MPs could adsorb and enrich other substances, resulting in more severe combined toxicological effects on organisms.The physical damage to the digestive tract of organisms and their accumulation and spread in the organism may be the main cause of oxidative stress and immune response.

Key words: microplastics, aquatic organisms, ecotoxicological effects
