海草床生态系统中微塑料的检测方法、赋存特征及毒理效应研究进展

Advances in Detection Methods,Fate Characteristics and Toxicological Effects of Microplastics in Seagrass Ecosystems

微塑料作为一种新污染物,在海洋环境中被频繁检出,对海洋生物和环境的生态风险受到越来越广泛的关注。海草床作为一个重要的海洋“蓝碳”生态系统,正受着微塑料污染的潜在威胁。本文梳理了海草床生态系统中微塑料的分离提取与定性定量检测方法,系统总结了海草床中微塑料的赋存特征,归纳了其对海草床生态系统的毒理效应。在此基础上,提出现有研究存在的问题以及未来的研究方向,以期为海草床生态系统中微塑料的风险评估和污染防控提供支撑。

Microplastics,as a type of emerging contaminant,are frequently detected in the marine environment,and the ecological risks to marine life and the environment have received more and more widespread attention.As an important marine“blue carbon”ecosystem,seagrass beds are also under the potential threat of microplastic pollution.This paper reviewed the separation,extraction,and qualitative and quantitative detection methods of microplastics in seagrass bed ecosystems,and systematically summarized the occurrence characteristics of microplastics,as well as the toxicological effects in seagrass bed ecosystems.On this basis,the existing problems and future research directions are proposed to provide support for the risk assessment and pollution prevention and control of microplastics in seagrass bed ecosystems.
