Abstract

This article investigates the distribution characteristics and deposition flux of atmospheric microplastics in desert agricultural regions surrounding the Taklamakan Desert in Xinjiang, China. Using active and passive sampling methods, the study identified microplastics primarily composed of polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polymethylmethacrylate (PMMA), and cellophane, with particle sizes mostly under 1000 μm. Fibrous microplastics dominated total suspended particulate matter (TSP) and atmospheric deposition samples, while film-like microplastics were prevalent in atmospheric dustfall. The measured deposition flux of atmospheric microplastics was 103.21 ± 22.12 particles/m²/day, lower than that reported in conventional agricultural areas, and sandstorm conditions were found to increase microplastic abundance in the atmosphere. The study highlights the influence of local agricultural practices and environmental conditions on microplastic composition and distribution, providing foundational data for future monitoring and risk assessment in desert agricultural ecosystems.
