Characterization of atmospheric microplastics in Hangzhou, a megacity of the Yangtze river delta, China
Summary
Researchers characterized atmospheric microplastics in Hangzhou, a major city in China's Yangtze River Delta. They found that airborne microplastics were predominantly fibers, with tire wear particles and polyethylene terephthalate being the most common polymer types. The annual dry deposition of microplastics across the urban area was estimated at nearly 17 tons, highlighting the scale of airborne microplastic pollution in densely populated regions.
Atmospheric microplastics in Hangzhou were predominantly fibers, with tires (27.0%) and PET (19.7%) as the dominant types. The annual MP dry deposition flux in the Hangzhou urban area was estimated to be 16.9 ± 2.9 tons.

Physicochemical characteristics of airborne microplastics of a typical coastal city in the Yangtze River Delta Region, China
Researchers characterized airborne microplastics in a coastal city in China's Yangtze River Delta, comparing daytime and nighttime concentrations and tracing their sources. They found that fibers were the most common shape, with polyester and rayon dominating, and that microplastic levels were higher during the day when human activity was greater. Atmospheric transport from both land and sea contributed to the pollution, highlighting that airborne microplastics are a significant and complex source of human exposure.
Unveiling the seasonal transport and exposure risks of atmospheric microplastics in the southern area of the Yangtze River Delta, China
Researchers measured airborne microplastics in the city of Ningbo, China, finding an average of 0.145 particles per cubic meter of air, with urban areas having about 70% more than surrounding rural regions. Most airborne microplastics were fibers smaller than 1 millimeter, mainly from synthetic textiles and local industry, with levels highest in winter. The study estimated that trillions of microplastic particles are suspended in the air over this single city, highlighting the scale of airborne microplastic exposure for urban populations.
Spatial and seasonal variations of airborne microplastics in the emerging megacity of Hangzhou, China
Researchers conducted a year-long sampling campaign across four urban zones in Hangzhou, China, to characterize airborne microplastics at human breathing height. The study found an average of 4.43 particles per cubic meter, with about 89% of particles smaller than 100 micrometers, predominantly fragments composed of polyamide and rubber, showing strong seasonal variation with lowest levels in summer.
