A review of atmospheric microplastics pollution: In-depth sighting of sources, analytical methods, physiognomies, transport and risks
This review provides an in-depth analysis of atmospheric microplastic pollution, examining sources, detection methods, physical characteristics, transport mechanisms, and health risks. Researchers found that indoor environments tend to contain higher concentrations of airborne microplastics than outdoor settings, and that current detection methods are limited in their ability to capture the smallest particles. The study emphasizes the need for standardized sampling procedures and more research into the health effects of inhaling microplastic particles.
Does microplastic really represent a threat? A review of the atmospheric contamination sources and potential impacts
This review examines airborne microplastics as emerging atmospheric contaminants that people inevitably inhale during normal breathing. Researchers found that fibers from synthetic textiles are the most common form of airborne microplastics, and their small size allows them to remain suspended in air and potentially cause health problems. The study discusses analytical methods used to measure airborne microplastics and calls for more research into their environmental and health impacts.
Plastic breath: Quantification of microplastics and polymer additives in airborne particles
