ClearVarious forms and deposition fluxes of microplastics identified in the coastal urban atmosphere
Researchers collected precipitation samples in a Chinese coastal city and found microplastics of multiple shapes deposited from the atmosphere, with seasonal variation in deposition rates. This is one of the first studies to document atmospheric microplastic deposition in a coastal urban environment.
Characteristics, distribution patterns and sources of atmospheric microplastics in the Bohai and Yellow Seas, China
Researchers investigated the characteristics, distribution patterns, and sources of atmospheric microplastics over the Bohai and Yellow Seas in China during summer and autumn 2022. The study provides new data on airborne microplastic pollution over oceanic regions, an area where information has been limited.
Characteristic of microplastics in the atmospheric fallout from Dongguan city, China: preliminary research and first evidence
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.
Algae: a frontline photosynthetic organism in the microplastic catastrophe
Researchers characterized airborne microplastic deposition in an urban area of China over 12 months, finding seasonal variation with higher deposition in winter and spring. Fibers accounted for the majority of particles, with polypropylene and polyester dominating.
Occurrence, characteristics, and factors influencing the atmospheric microplastics around Jiaozhou Bay, the Yellow Sea
Atmospheric microplastics collected around Jiaozhou Bay in China were deposited at rates of up to 80 items per square meter per day, with seasonal variation driven by monsoons — higher deposition in dry seasons — and fragments and polyethylene being the dominant forms. The estimated annual input of microplastics into this bay via atmospheric deposition alone is over 7.6 tons, highlighting that air-to-sea transfer is a substantial and seasonally dynamic pathway for marine microplastic contamination.
Occurrence of microplastics in the seawater and atmosphere of the South China Sea: Pollution patterns and interrelationship
Researchers investigated microplastic pollution in both seawater and the atmosphere of the South China Sea, revealing distribution patterns and an interrelationship between marine and airborne microplastic contamination in the region.
New insights into the microbial succession and health risks of atmospheric plastispheres
Researchers conducted a two-month outdoor experiment to study how bacteria colonize atmospheric microplastics and found that while initial colonization was polymer-specific, communities gradually converged over time. Seven pathogenic species were specifically enriched on plastic surfaces, with some appearing only in later stages of biofilm development, suggesting that airborne microplastics may serve as carriers that accumulate and potentially transmit harmful bacteria.
Atmospheric deposition of microplastics in the megalopolis (Shanghai) during rainy season: Characteristics, influence factors, and source
Researchers characterized atmospheric microplastic deposition in Shanghai during the rainy season, finding that rainfall events significantly increased deposition rates, with fibers dominating and sources linked to both local urban activities and long-range atmospheric transport.
Atmospheric deposition as a pathway for microplastic transport to the marine environment: Temporal variation and environmental factors
A year-long study in a South Korean coastal bay found that atmospheric dry and wet deposition delivers a measurable and seasonally variable load of microplastics to the marine surface, with wind speed, rainfall, and dust events driving the temporal patterns. This confirms that the atmosphere is a significant and often overlooked transport route for microplastics from land to ocean.
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.
Atmospheric microplastics in the Northwestern Pacific Ocean: Distribution, source, and deposition
Researchers documented atmospheric microplastic distribution in the Northwestern Pacific Ocean, finding abundances ranging from 0.0046 to higher levels and identifying sources and deposition patterns that contribute to marine microplastic pollution from airborne transport.
Comparative study on physicochemical characteristics of atmospheric microplastics in winter in inland and coastal megacities: A case of Beijing and Shanghai, China
Researchers compared airborne microplastic pollution during winter in Beijing, an inland city, and Shanghai, a coastal city in China. They found notable differences in the shapes, sizes, and polymer types of microplastics between the two cities, reflecting their distinct urban and industrial environments. The study provides evidence that local geography and economic activity significantly influence the characteristics of atmospheric microplastic contamination.

Researchers conducted a year-long monitoring campaign of deposited and suspended atmospheric microplastics in Handan, an industrial city in northern China. They found strong seasonal variations linked to wind patterns and industrial emissions, with human inhalation exposure posing a measurable health risk.

Researchers measured airborne microplastic concentrations near a marine litter hotspot in a coastal village in Taiwan and found an average of 1.35 particles per cubic meter of air, with the highest levels in spring. The study provides evidence that accumulated marine litter on coastlines can serve as a source of atmospheric microplastics, potentially affecting air quality in nearby communities.

Atmospheric microplastics at a southern China metropolis: Occurrence, deposition flux, exposure risk and washout effect of rainfall
Researchers measured airborne microplastics in Guangzhou, a major city in southern China, finding them throughout the year with higher levels during the rainy season. They estimated that adults in the city inhale tens of thousands of microplastic particles annually through normal breathing. Rainfall helped wash microplastics out of the air, but it also deposited them onto surfaces where they can enter water and soil, creating another pathway for human exposure.
