ClearAtmospheric Microplastic Particulate Matter in an Urban Roadside: Case of Bandar Lampung City, Indonesia
Researchers sampled airborne microplastics at four locations across Bandar Lampung City, Indonesia, including industrial zones, residential neighborhoods, busy roads, and the city center. They found microplastic concentrations ranging from 0.002 to 0.02 particles per cubic meter of air, with fibrous shapes and PET plastic most common. Industrial areas had the highest total particulate levels, and northern parts of the city appear to be a likely source of airborne microplastics carried by traffic. This study adds to growing evidence that city dwellers are breathing in microplastics simply from the air around them.

Microplastics in the urban atmosphere: Sources, occurrences, distribution, and potential health implications
This review summarizes research on airborne microplastics in cities, finding that indoor sources like textiles and outdoor sources like traffic-related plastic particles are major contributors. Microplastic concentrations in urban air can be significant, especially in densely populated areas, and people can inhale these particles daily. The health implications of breathing in microplastics are still being studied, but early evidence suggests they may cause lung inflammation and other respiratory problems.

Micro-Raman spectroscopy identified the dominant polymer types present in traffic-adjacent air.
Microplastic Distribution Model in Ambient Air PM2.5 Around the Medan Industrial Area, North Sumatra
Researchers investigated the distribution of microplastics in fine particulate matter around an industrial area in Medan, North Sumatra, finding between 41 and 92 particles per sample. The dominant form was fragments, making up 62% of detected microplastics, and their distribution was influenced by wind direction and nearby pollution sources. The study suggests that industrial areas are significant contributors to airborne microplastic contamination in the surrounding environment.
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.
Exploration of microplastic concentration in indoor and outdoor air samples: Morphological, polymeric, and elemental analysis
Researchers measured airborne microplastics in indoor and outdoor environments in Islamabad, Pakistan, finding that indoor air contained nearly five times more microplastics than outdoor air. Classrooms had the highest contamination at about 6 particles per cubic meter, with fibers being the most common shape and polyester (PET) the most common plastic type. These findings highlight that people are continuously inhaling microplastics, especially indoors.
Plastic rain—Atmospheric microplastics deposition in urban and peri-urban areas of Patna City, Bihar, India: Distribution, characteristics, transport, and source analysis
Researchers measured microplastic particles falling from the sky in Patna, India, finding nearly 2,000 particles per square meter per day in urban areas. The plastic "rain" was mostly tiny fibers and fragments made of common plastics like PET and polypropylene. This study shows that breathing outdoor air is another way people are exposed to microplastics, especially in cities.
