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.
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.
Determination of microplastics in university interior environments
This study measured airborne microplastic concentrations in indoor environments at a university, finding particles in air samples from multiple indoor settings. Results contribute to evidence that indoor air represents a significant daily source of microplastic inhalation exposure, particularly given the time people spend in closed indoor environments.
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.
Determination of microplastics in university interior environments
This study measured microplastic concentrations in indoor air at university facilities, building on evidence that indoor environments are significant sites of microplastic exposure through inhalation. Particles were detected in multiple indoor settings, contributing to growing evidence that daily indoor air exposure is a notable route of human microplastic intake.
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.
Study of suspended microplastics in indoor air to assess human exposure through inhalation
Researchers studied suspended microplastics in indoor air to evaluate human exposure through inhalation. The study measured airborne microplastic concentrations in indoor environments, contributing to the growing body of evidence that inhalation represents a significant and underappreciated route of human microplastic exposure.
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.
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.
Morphological and Chemical Analysis of Indoor Airborne Microplastics: Implications for Human Health in Ahvaz, Iran
Researchers collected indoor airborne microplastics and performed detailed morphological and chemical characterization, assessing the particle types, polymer identities, and surface properties of what people inhale in enclosed spaces. The study found a diverse mixture of synthetic fiber fragments and plastic particles in indoor air.
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.
Indoor microplastics: a comprehensive review and bibliometric analysis
This review summarizes research on microplastic pollution inside buildings, where people spend most of their time. Indoor environments generally have higher microplastic concentrations than outdoors, with fiber-shaped particles from synthetic textiles being the most common type. Since people inhale and ingest these particles daily, indoor microplastic exposure may be a significant and underappreciated route of human health risk.
Indoor Microplastics: A Comprehensive Review and Bibliometric Analysis
This comprehensive review and bibliometric analysis summarizes research on indoor microplastic contamination, covering sampling methods, identification techniques, and concentration levels in dust, deposition, and air samples. Fiber-shaped microplastics are the most commonly detected indoors, with dust and deposition samples showing higher concentrations than air samples.
Morphological and chemical analysis of indoor airborne microplastics: implications for human health in Ahvaz, Iran
Researchers analyzed airborne microplastics inside homes, offices, and commercial buildings in Ahvaz, Iran, finding significant concentrations that vary by building type and season. Using Raman spectroscopy and electron microscopy, they identified various polymer types and estimated annual inhaled doses based on typical occupancy patterns. The study found that people may be inhaling meaningful amounts of microplastics indoors, where they spend most of their time, posing potential respiratory and other health risks.
Long-term assessment of microplastics in indoor high school air: Abundance, sources, and polymeric analysis
Researchers monitored airborne microplastic concentrations in indoor high school environments over an extended period, identifying sources and seasonal patterns. Indoor air contained substantial microplastic levels, with textile fibers and outdoor infiltration contributing to persistent classroom air contamination.
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.

Researchers used a breathing thermal manikin to simulate human exposure to airborne microplastics inside three apartments and found that every sample contained microplastic particles. Polyester and polyamide fibers from textiles were the most common types detected. The study estimates that people inhale meaningful quantities of microplastics indoors, identifying a significant but understudied route of human exposure.
