Measuring airborne nanoplastics using aerosol physics
AI summary Read the abstract
Differential mobility particle sizing (DMPS), a technique from aerosol physics, can be adapted to measure and source-attribute airborne nanoplastic particles in ambient air. Detecting airborne nanoplastics is a critical emerging challenge because inhalation is a direct human exposure route, yet analytical methods for measuring plastic particles at nanometer scales remain limited.
Andrea Stoellner explains how differential mobility particle sizing (DMPS) can help identify the sources of airborne plastic particles.

Novel Techniques in Quantifying Microplastics in Atmospheric Particles
AI summary Read the abstract
This study developed novel analytical techniques for detecting and quantifying microplastics in atmospheric particles, addressing methodological gaps in measuring airborne plastic contamination in both remote and urban environments. Atmospheric microplastics represent an inhalation exposure pathway that is increasingly recognized as a significant contributor to total human microplastic body burden, making robust atmospheric quantification methods essential for health risk assessment.
Airborne Microplastics
AI summary Read the abstract
Microplastics and synthetic microfibers are pervasive in both indoor and outdoor air, originating from textiles, tire wear, and other everyday sources, meaning humans are continuously inhaling these particles. Airborne microplastic exposure represents an underappreciated inhalation route that may have significant respiratory and systemic health consequences.
Airborne Microplastics
AI summary Read the abstract
Researchers reviewed how microplastics and synthetic microfibers become airborne from sources like clothing and tire wear, contaminating both indoor and outdoor air. Because humans inhale thousands of microplastic particles daily, airborne microplastics represent a direct and underappreciated exposure route with potential respiratory health implications.
Airborne Microplastics
AI summary Read the abstract
Microplastics and synthetic microfibers are released into both indoor and outdoor air from sources including textiles and tire abrasion, making airborne inhalation a significant and often overlooked human exposure route. Indoor air concentrations can exceed outdoor levels, meaning people may be inhaling microplastics continuously in their homes and workplaces with unknown long-term respiratory health consequences.
