微塑料污染的水生生态毒性与载体作用

近年来,微塑料的水生生态环境污染与生态毒害问题引起了科学界的广泛关注。在总结国内外相关研究的基础上,本文对水生态环境中微塑料的来源、形成与分布展开分析;对微塑料污染的生态毒性研究进展给予评述;并深入探讨了微塑料在生态系统中扮演的多重载体角色。鉴于微塑料污染的严峻现实,我国应尽快开展有关微塑料环境污染和生态毒理方面的系统研究,并辅以政策引导和经济支持。

The Ecotoxicity and Carrier Function of Microplastics in the Aquatic Environment

Increasing attention has been paid to the microplastic pollution in aquatic ecosystems and the subsequent ecological toxic effects. The present review summarized the source, formation and distribution of microplastics in the aquatic environment based on literature research, commented on the current ecotoxicological studies on microplastics, and further discussed the multiple carrier roles of microplastics in aquatic ecosystems. In view of the severe pollution status of microplastics, we suggest that integrated studies on microplastic pollution and ecological mechanisms are urgently needed in China, with political and financial supports from the government.
