Assessing 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.
Microplastic characterization based on the number of occupants
Microplastics were found in indoor dust from an apartment, office, and school in Surabaya, Indonesia, with school environments having the highest concentrations. The findings confirm that people — especially children — are continuously exposed to microplastics through the air they breathe indoors.

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.
Assessing Microplastic Distribution in Indoor Environments: A Case Study of a University Facility in Kuala Lumpur
Microplastics were detected in the indoor air and settled dust of a Malaysian university building at concentrations averaging 156 particles per cubic metre in offices and 104 in classrooms, with estimated daily adult intakes of over 150 microplastic particles per kilogram of body weight per day. These findings confirm that indoor environments — where people spend the majority of their time — are a significant and often overlooked route of human microplastic inhalation and ingestion.
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.
Airborne microplastic contamination across diverse university indoor environments: A comprehensive ambient analysis
Researchers measured airborne microplastics across different indoor spaces at a university and found that people in those buildings inhale an estimated 180 to 240 microplastic particles daily. The most common types found were nylon, PTFE, polypropylene, and polyethylene, with fragments showing rough edges from wear and tear. This study highlights that indoor air is a significant and often overlooked source of microplastic exposure for people who spend most of their time indoors.
Human inhalation exposure assessment of the airborne microplastics from indoor deposited dusts during winter in Dhaka, Bangladesh
Researchers analyzed indoor dust from 15 homes in Dhaka, Bangladesh and found microplastics in every sample, with concentrations suggesting that people inhale thousands of microplastic particles daily during winter when ventilation is reduced. The most common types were polypropylene, polyethylene, and polyester from household items, and estimated daily inhalation exposure was highest for children relative to their body weight.
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
Researchers collected airborne microplastic samples from indoor and outdoor environments at a Malaysian university campus, finding microplastics present in all locations with higher concentrations indoors and fiber morphologies predominating, suggesting occupants are continually exposed via inhalation.
Microplastics comparison of indoor and outdoor air and ventilation rate effect in outskirts of the Seoul metropolitan city
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.
Microplastic Fallout in Different Indoor Environments
Researchers tracked microplastic fallout in indoor environments (dormitory, office, corridor) over three months and found that higher human activity on workdays and airflow from air conditioning increased microplastic deposition rates, identifying indoor air as a significant exposure route.
