As emerging environmental contaminants, microplastics may cause potential hazard to global ecosphere (including water, soil and air) and human health. To date, the occurance and ecological effects of microplastics in water and soil were systematically summarized. However, there are few reviews of microplastics in air (i.e. airborne microplastics). Recently, microplastics have been observed in atmospheric fallout collected from some areas. Although the studies are limited, most of the researches showed that synthetic textiles are the main source of airborne microplastics, and fibers are the dominant shape. Airborne microplastics are contributors to microplastic pollution in aquatic and soil environments. In addition, airborne microplastics can be directly inhaled and posed health risks to humans. Therefore, this review summarized the current knowledge and provide insights into further research to better understand airborne microplastics and their risks to human.

作为新兴的环境污染物，微塑料可能对全球生态圈（包括水、土壤和空气）和人类健康造成潜在危害。迄今为止，系统总结了微塑料在水和土壤中的发生和生态效应。然而，关于空气中的微塑料（即空气中的微塑料）的评论很少。最近，在从一些地区收集的大气沉降物中观察到微塑料。尽管研究有限，但大多数研究表明，合成纺织品是空气中微塑料的主要来源，而纤维是主要形状。空气中的微塑料是水生和土壤环境中微塑料污染的贡献者。此外，空气中的微塑料可被直接吸入，对人类造成健康风险。所以，
