Characteristics, sources and potential ecological risk of atmospheric microplastics in Lhasa city
Researchers characterized atmospheric microplastics collected at a monitoring site, identifying their sources, size distribution, polymer composition, and potential ecological risks from aerial deposition to terrestrial and aquatic ecosystems.
Microplastic atmospheric dustfall pollution in urban environment: Evidence from the types, distribution, and probable sources in Beijing, China
Researchers collected atmospheric dustfall samples across urban Beijing and analyzed the types, distribution, and likely sources of airborne microplastics. They found that synthetic fibers from textiles and fragments from various plastic products were the dominant forms, with concentrations varying by location and proximity to pollution sources. The study provides evidence that urban atmospheric microplastic pollution is widespread and likely linked to daily human activities and industrial processes.
Microplastics in the atmospheric of the eastern coast of China: different function areas reflecting various sources and transport
Atmospheric sampling at two sites in a Chinese coastal city found microplastics suspended in the air at both downtown and industrial locations, but with different dominant sources — lifestyle and consumer products in the city center versus industrial activity in the industrial zone. The finding that microplastics are transported through the atmosphere confirms that people in urban areas are inhaling plastic particles regardless of proximity to industrial facilities.
First quantification and chemical characterization of atmospheric microplastics observed in Seoul, South Korea
Researchers conducted the first measurement of airborne microplastics across five outdoor sites in Seoul, South Korea, finding plastic particles everywhere from business districts to urban forests. Microplastic levels were higher in areas with more human activity and during weekdays versus weekends. Polypropylene and PET were the most common types, suggesting that everyday plastic products are a major source of airborne microplastic pollution in cities.
An important source of terrestrial microplastics‐atmospheric deposition: A microplastics survey based on Shaanxi, China
A six-month atmospheric sampling campaign across ten cities in Shaanxi Province, China detected microplastics in all air deposition samples, including both wet (rain/snow) and dry deposition. The most abundant polymer types were PET, polyacrylonitrile, PE, and PP — consistent with textiles and packaging as key sources — and concentrations were highest in the provincial capital Xi'an, correlating with urban population density. The study confirms that atmospheric fallout is a significant and widespread route by which microplastics enter terrestrial environments far from any obvious plastic source.
Atmospheric deposition of microplastics at a western China metropolis: Relationship with underlying surface types and human exposure
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.
A comprehensive risk assessment of microplastics in soil, water, and atmosphere: Implications for human health and environmental safety
This comprehensive study analyzed microplastic contamination across soil, water, and air in China, finding that polypropylene, polyethylene, and polystyrene were the most common types. While current risk assessments rate the direct ecological danger as low, the study warns that microplastics interact with other pollutants in ways that amplify their combined health and environmental risks, and that existing assessment models may underestimate the true danger.
Sources and distribution of atmospheric microplastics in Northwest China river valleys via land use
This study quantified suspended atmospheric microplastics across eight land use types in Lanzhou, northwest China, finding a mean abundance of 4.5 particles/m³ with peaks in industrial and residential areas. Land use type was the strongest predictor of MP concentration, highlighting urban and agricultural activities as key emission drivers.
Occurrence and sources of microplastics in dust of the Ebinur lake Basin, northwest China
Researchers investigated microplastic distribution in atmospheric dustfall across the Ebinur Lake Basin in northwest China, sampling four land-use types monthly for a year. They found construction land had the highest microplastic content (28.61 mg/kg), with films (46.85%) and PE/PP polymers dominating, and identified daily plastic products and industrial packaging as primary sources.
Atmospheric deposition of microplastics in a rural region of North China Plain
Researchers investigated atmospheric microplastic deposition in a rural area of the North China Plain, finding significant quantities of microplastics deposited through both dry and wet pathways, with fibers and polyethylene being the dominant types.

Researchers characterized microplastics in atmospheric fallout collected in Dongguan City, China, finding that airborne microplastics are deposited daily and that urban areas generate significant atmospheric microplastic emissions.
Assessment of suspended atmospheric microplastics in Tianjin Binhai New Area: characterization, human health risks, and correlation with weather conditions and Air Quality Index
Researchers measured airborne microplastics in an urban area of Tianjin, China, and found them in every sample collected during autumn and winter. The particles were mostly fibers, with polyethylene terephthalate and polyethylene among the most common types, and concentrations varied with weather conditions like humidity and barometric pressure. A health risk assessment suggested that residents face measurable exposure to airborne microplastics, raising concerns about long-term inhalation risks.
[Distribution, Respiratory Exposure, and Traceability of Atmospheric Microplastics in Yichang City].
Researchers sampled airborne microplastics at 16 locations across Yichang City, China, and found them in every area, with the highest concentrations settling over urban residential neighborhoods. The particles were mostly polyester fibers and came predominantly from nearby sources rather than long-range transport. Daily inhalation estimates were calculated for both adults and children, highlighting indoor and outdoor respiratory exposure as a meaningful human health concern that warrants tighter monitoring.

Occurrence, influencing factors and sources of atmospheric microplastics in peri-urban farmland ecosystems of Beijing, China
Researchers measured atmospheric microplastic deposition in farmland areas on the outskirts of Beijing and found an average of about 167 particles per square meter per day settling from the air.
