ClearAssessing the concentration, distribution and characteristics of suspended microplastics in the Malaysian indoor environment
Researchers measured airborne microplastic levels inside offices, classrooms, apartments, and homes across Malaysia over six weeks. Microplastics were found in every indoor environment tested, with fibers being the most common type, and people in homes were estimated to inhale more microplastics daily than those in offices or classrooms. The findings highlight that indoor air is a significant and often overlooked source of microplastic exposure for people.
Temporal Variations and Characteristics of Microplastics in Indoor and Outdoor Air
Researchers measured microplastic concentrations in indoor and outdoor air across different seasons and found levels were similar in both environments, averaging about 1.8–2.7 particles per cubic meter. The dominant plastic type was PET, and turbulent airflow and human activity — not season or day of week — were the main drivers of indoor microplastic levels.
Airborne Microplastics in Indoor and Outdoor Environments at Universiti Teknologi Malaysia, Kuala Lumpur Campus

First overview of microplastics in indoor and outdoor air
This study provided one of the first comprehensive overviews of microplastic contamination in both indoor and outdoor air, establishing that microplastics are airborne and that indoor environments may have higher concentrations than outdoors due to synthetic materials and textiles. The findings raised new concerns about inhalation as a pathway for human microplastic exposure.

Researchers measured airborne microplastics both indoors and outdoors in buildings near Seoul, finding that indoor concentrations were 1.8 times higher than outdoor levels. Polyester fibers from clothing and furnishings were the most common type, and lower ventilation rates led to higher indoor microplastic levels, meaning the air people breathe at home and work may be a significant source of microplastic exposure.
Characterization and quantification of microplastics in indoor environments
Researchers measured airborne microplastics in indoor spaces including offices, labs, dining halls, and dormitories. Dormitories had the highest microplastic levels, with fibers being the most common shape found. The study highlights that people are regularly inhaling microplastics indoors, where they spend the majority of their time.

This comprehensive review examines microplastic pollution in indoor and outdoor air, highlighting exposure pathways and emerging health risks. Researchers found that poorly ventilated indoor spaces have the highest concentrations of airborne microplastics, while factors like humidity and ventilation significantly influence pollution levels, raising concerns about chronic inhalation exposure.
Study of suspended microplastics in indoor air to assess human exposure through inhalation
Researchers investigated suspended microplastics in indoor air to assess the extent of human exposure through inhalation. The study quantified airborne microplastic particles in indoor settings, providing data on a potentially important but understudied route of daily microplastic intake for the general population.
A review of atmospheric microplastics pollution: In-depth sighting of sources, analytical methods, physiognomies, transport and risks
This review provides an in-depth analysis of atmospheric microplastic pollution, examining sources, detection methods, physical characteristics, transport mechanisms, and health risks. Researchers found that indoor environments tend to contain higher concentrations of airborne microplastics than outdoor settings, and that current detection methods are limited in their ability to capture the smallest particles. The study emphasizes the need for standardized sampling procedures and more research into the health effects of inhaling microplastic particles.
Exposure to microplastics in the upper respiratory tract of indoor and outdoor workers
Researchers measured microplastic presence in the upper respiratory tracts of indoor office workers and outdoor couriers using nasal lavage and sputum samples. The study found microplastics in both groups, with office workers showing significantly higher nasal contamination than couriers, and the dominant plastic types differing between indoor and outdoor workers.
Microplastics exposure levels based on building composition and usage in built environmnet
This study assessed indoor microplastic exposure levels across different building types and usage patterns, finding that building composition materials and occupancy behavior significantly affect airborne MP concentrations and thus human inhalation exposure in built environments.
Characterization of microplastics in indoor and ambient air in northern New Jersey
Researchers characterized airborne microplastics in both indoor and outdoor environments across northern New Jersey, finding fibers, films, and fragments of common plastic types in offices, classrooms, hallways, and homes. Indoor microplastic concentrations were generally higher than outdoor levels, with deposition rates varying by location and particle size. The study adds to growing evidence that indoor air is a significant pathway for human microplastic exposure through inhalation.
A systematic review of airborne microplastics emissions as emerging contaminants in outdoor and indoor air environments
This systematic review compared microplastic levels in indoor and outdoor air around the world. Indoor air often contains more microplastics than outdoor air — largely from synthetic clothing and household items — meaning our homes and workplaces may be significant sources of daily microplastic exposure.
