摘　　要：微塑料(MPs)作为一种新型的环境污染物,其对动物和人类健康的危害受到广泛关注。研究显示,动物消化道和呼吸道是MPs主要的暴露途径,MPs诱导的氧化应激和炎症反应能够导致肠道功能紊乱、菌群失调以及肺部损伤,严重影响动物的健康状况。基于国内外已有研究,本文综述了当前MPs对于动物的主要暴露途径、毒性作用和毒性机制的研究进展,有助于系统认识MPs对动物健康的危害,为进一步在渔业和畜禽生产过程中开展MPs的风险评估提供参考。As a new type of environmental pollutant,microplastics(MPs)have attracted extensive attention for their harm to animal and human health.Studies have shown that the digestive tract and respiratory tract of animals are the main exposure routes of MPs,and the oxidative stress and inflammation induced by MPs can lead to intestinal dysfunction,flora disturbance and lung injury,which seriously affect the health of animals.Based on existing studies at home and abroad,this paper reviewed the current research progress on the main exposure routes,toxic effects and toxic mechanisms of MPs to animals,which is helpful to systematically understand the harm of MPs to animal health and provide references for further risk assessment of MPs in fisheries and livestock production.
