Potential Impact of Urban Land Use on Microplastic Atmospheric Deposition: A Case Study in Pristina City, Kosovo
AI summary Read the abstract
This study examined whether urban land use types predict atmospheric microplastic deposition in Pristina, Kosovo, collecting samples at seven sites during a 10-day period. Results showed that microplastic deposition varied with land use, suggesting that urban activities are a significant source of airborne microplastic fallout.
Microplastics (MPs) pervade various ecosystems, including urban landscapes. The aim of this study was to determine whether the presence of MPs in atmospheric deposition samples is related to land use. For this purpose, atmospheric deposition was collected from 15 to 25 March 2021 at seven research sites in the city of Pristina (Kosovo). Each research site was characterized by different land use. Collected atmospheric deposition samples were analyzed in the laboratory, and then the filtered samples were assessed using a light microscope. The type and size of microplastics in the samples were defined and statistically analyzed. The highest number of total MPs was noted on the highway, while the lowest one was near to the park. A positive relationship was observed between the number of total MPs and the proportion of areas classified as “roads and associated areas” in the land use of the analyzed research sites. Furthermore, a negative relationship was found between the number of total MPs and the proportion of areas classified as “green urban areas”. Based on our preliminary research, it can be observed that the type of land use may have a key role in MPs’ atmospheric deposition.

AI summary Read the abstract
Researchers conducted the first comprehensive assessment of airborne microplastic deposition across 23 sites in Lahore, Pakistan, covering areas with diverse human activities. They identified fibers as the dominant microplastic type in atmospheric fallout, with concentrations varying by land use and proximity to industrial areas. The study establishes baseline data on atmospheric microplastic pollution in a major South Asian city and identifies key contributing sources.
Atmospheric deposition of microplastics at a western China metropolis: Relationship with underlying surface types and human exposure
AI summary Read the abstract
Researchers measured microplastic fallout from the atmosphere in Chengdu, China, and found that the type of ground surface below -- urban, green space, or mixed -- influenced how much airborne microplastic accumulated. Using a probability model, they estimated that people are exposed to significant amounts of airborne microplastics during outdoor activities, adding to the growing evidence that we inhale these particles daily.
The atmospheric microplastics deposition contributes to microplastic pollution in urban waters
AI summary Read the abstract
Researchers investigated how atmospheric deposition contributes to microplastic pollution in urban waters. The study found that microplastic deposition fluxes were higher during wet weather than dry weather and showed moderate to strong correlations with atmospheric conditions, demonstrating that airborne microplastic fallout is a meaningful source of contamination in urban water environments.
