ClearAtmospheric 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.

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.
Regional and climatic variations in atmospheric microplastic deposition: A study throughout Iran

Atmospheric deposition of microplastics in shiraz, iran
Researchers measured atmospheric microplastic deposition during successive dry and rainy events over eight consecutive days at six sites in and around Shiraz, Iran, including a remote non-urbanised location. The study found that microplastic abundance and deposition flux increased progressively during dry periods and was similar across urban and remote sites, suggesting widespread atmospheric transport and redistribution of microplastics via rainfall scavenging.
Atmospheric microplastic transport and deposition to urban and pristine tropical locations in Southeast Asia
Researchers measured atmospheric microplastic deposition at urban and pristine sites in Malaysia across two monsoon seasons and found microplastics at all locations, including a remote tropical forest. Deposition rates ranged from 114 to 689 particles per square meter per day, with monsoon wind patterns influencing the transport of particles over long distances. The study demonstrates that atmospheric transport is a significant pathway for spreading microplastic contamination to even remote ecosystems in Southeast Asia.
Various 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.
The deposition of atmospheric microplastics in Jakarta-Indonesia: The coastal urban area
Researchers characterized atmospheric microplastic deposition in Jakarta, Indonesia over 12 months, finding deposition rates of 3-40 particles per square meter per day with fibers as the dominant shape, and higher deposition during the rainy season compared to the dry season.
Microplastic in atmospheric fallouts of a developing Southeast Asian megacity under tropical climate
A year-long monitoring study of atmospheric microplastic fallout in a Southeast Asian megacity found deposition rates of 71–917 items/m²/day dominated by fibers, with no significant correlation with rainfall or wind — contrary to patterns seen in temperate climate studies.
