微塑料在肠道的蓄积毒性及其生态危害研究进展

Progress on cumulative Toxicity and Ecological Hazards of Microplastics in Intestinal Tract

微塑料是一种潜在的持久性有机污染物,其污染已成为全球关注的环境问题,是近年来的研究热点.微塑料被生物体摄入体内后,可通过食物链污染各个营养级,最终威胁人类健康.肠道作为微塑料主要存在的场所和进入循环系统的通道,其与微塑料的关系对理解微塑料的健康风险具有重要意义.该文梳理了近几年有关微塑料在肠道蓄积以及对肠道和肠道菌群影响的研究报告,以期更好地理解微塑料对生态系统和人体健康的风险.

As an important type of potential persistent organic pollutants,the pollution problem of microplastics has become a global concern and a hot research topic in recent years.When ingested by organisms,microplastics can contaminate all nutrient levels through the food chain,ultimately threatening human health.The intestinal tract is the main place where microplastics exist and the passage into the circulatory system.The relationship between intestinal tract and microplastics is important for understanding the health risks of microplastics in ecosystems.In order to better understand ecological risks of microplastics,the recent studies on the accumulation of microplastics in the intestinal tract and their effects on the intestinal and gut microbiota are reviewed in this paper.
