摘要:
沙尘暴PM2.5是造成大气污染和危害人体健康的重要因素之一。沙尘暴PM2.5组成成分复杂，影响范围广，进入机体潜在致敏靶点可引起多种健康损伤。本文概述近年来沙尘暴PM2.5导致机体生物学效应及相关机制的研究现状，包括炎性作用、氧化应激、免疫毒性、DNA损伤等，旨在为进一步深入研究沙尘暴PM2.5造成的生物学效应及具体作用机制提供依据。
Abstract: Dust storm fine particles (PM2.5) are one of the major factors resulting in air pollution and threatening human health. Owing to complex components and a wide coverage, dust storm PM2.5 can cause multiple adverse health effects through potential sensitive targets. In this paper, recent studies reporting the biological effects and potential mechanisms of toxicity induced by dust storm PM2.5 exposure were reviewed and presented from four perspectives including inflammatory response, oxidative stress, immune toxicity, and DNA injury. This review aimed to provide a theoretical basis for further related studies.
