Introduction Deposition rate Microplastics (MPs) have gradually attracted attention; however, people have paid limited attention to the existence of airborne microplastics, especially in indoor environments.Our results also show that the frequency of human activities is one of the main factors leading to changes in the content of microplastics in indoor air, and turbulence caused by airflow will lead to the migration of microplastics in the indoor environment.

Deposition rate Microplastics (MPs) have gradually attracted attention; however, people have paid limited attention to the existence of airborne microplastics, especially in indoor environments.Our results also show that the frequency of human activities is one of the main factors leading to changes in the content of microplastics in indoor air, and turbulence caused by airflow will lead to the migration of microplastics in the indoor environment. In this study, we tracked microplastic deposition in offices, laboratories, dining halls, and dormitories Plastics have been widely used around the world because of their corrosion resistance, light strength, and low cost [1].MPs can be found in many environmental mediums, such as brine, freshwater, potable water, outlet water, soil, sludge, precipitate, and submarineIn 2019, researches divided plastics roughly into four categories based on their size: large plastics (>25 mm), medium plastics (5-25 mm), microplastics (
