Characterising microplastics in indoor air: Insights from Raman imaging analysis of air filter samples

Researchers analyzed air filters from an air conditioner and a computer that had been running indoors for half a year and found they had collected an estimated 73 to 88,000 microplastic fibers each. Most of the identified microplastics were PET fibers likely shed from synthetic clothing and textiles. This study confirms that people are continuously breathing in microplastic fibers in their homes and offices, and suggests air filters could serve as monitors for indoor microplastic exposure.

Microplastics in indoor deposition samples in university classrooms

Researchers analyzed microplastic contamination in dust collected from university classrooms and found particles from clothing fibers, shoes, and school supplies. Most particles were polyamide and polypropylene fibers ranging from 120 to over 2,000 micrometers in size, and surface damage on the particles suggests they may be breaking down into even smaller nanoplastics over time. Since people spend most of their time indoors, this indoor microplastic exposure is an important and underappreciated route of human contact with these particles.

Correlating Scanning Electron Microscopy and Raman Microscopy to Quantify Occupational Exposure to Micro- and Nanoscale Plastics in Textile Manufacturing

Researchers used a correlative SEM-Raman microscopy approach to quantify airborne micro- and nanoplastic particle exposure during polyester microfiber production in a textile manufacturing facility. The study found that sub-micrometer particles dominated the workplace aerosol, with PET being the main process-related nanoplastic type, providing substance-specific occupational exposure data that has been largely lacking in this field.

Assessment of Indoor Microplastic Particles Pollution in Selected Sites of Mosul City

Researchers surveyed indoor microplastic pollution across 90 locations in Mosul, Iraq, including kindergartens, hospitals, offices, and shops. They found the highest microplastic levels in kindergartens and the lowest in medical clinics, with fibers being the most common shape. Polystyrene, PET, and polypropylene were the dominant plastic types, suggesting that indoor environments are a meaningful source of human microplastic exposure.

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.

Characteristics and influencing factors of airborne microplastics in nail salons

Researchers measured airborne microplastic concentrations in nail salons and found average levels of 46 particles per cubic meter, significantly higher than typical indoor environments. The predominant microplastic types were acrylic, rubber, and polyurethane fragments smaller than 50 micrometers, linked to nail treatment materials and plastic building features. The study suggests that nail salon workers face elevated microplastic exposure, with an estimated annual inhalation of nearly 68,000 particles.
