ClearStudy 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.
Exploring microplastics sources in indoor environments, an emerging pollutant
This study explores microplastics as an emerging indoor air and surface pollutant, examining the diverse sources that contribute to microplastic presence within indoor environments and characterizing the pathways by which people may be exposed.
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.
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.
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 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.
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.
Microplastics Differ Between Indoor and Outdoor Air Masses: Insights from Multiple Microscopy Methodologies
Researchers compared airborne microplastic concentrations inside and outside buildings in coastal California using multiple microscopy techniques. The study found that microplastic composition and abundance differed between indoor and outdoor air masses, with indoor environments containing distinct microplastic profiles, suggesting that people are exposed to different types of airborne microplastics depending on whether they are indoors or outdoors.
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.
An Occupant-Based Overview of Microplastics in Indoor Environments in the City of Surabaya, Indonesia
Airborne microplastic deposition in settled indoor dust was measured in residential and commercial buildings in a city environment, providing an occupant-based assessment of indoor microplastic exposure. Microplastics smaller than 5 mm were deposited at measurable rates in all sampled indoor settings, with fiber shapes dominating the settled dust contamination.
Indoor microplastics and bacteria in the atmospheric fallout in urban homes
Researchers measured indoor airborne microplastics and bacteria across different rooms in 20 urban homes. The study identified nearly 24,000 microplastic particles of 21 polymer types and found that microplastic abundance varied by room type and usage patterns, with a significant correlation between microplastic concentrations and bacterial community structure in the home environment.
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.
Microplastic levels in the indoor air of buildings based on plastic waste recycling in Indonesia
Researchers measured airborne microplastic concentrations inside a miniature building constructed from recycled plastic waste in Indonesia over 30 days, finding an average deposition rate of 30.8 particles/m2/day during the dry season with passive air sampling and microscopic analysis.
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.
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.
Systematic review of microplastics and nanoplastics in indoor and outdoor air: identifying a framework and data needs for quantifying human inhalation exposures
This systematic review is the first to examine microplastic levels in both indoor and outdoor air and estimate how much people inhale. The findings suggest we are breathing in microplastic particles daily, with indoor air often containing higher concentrations due to synthetic textiles and household materials.
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.
