Microplastics in ambient air: a review of atmospheric abundance, human exposure and urgent research needs

AI summary · Read the abstract

This review pulled together findings from 84 studies to show that tiny plastic bits called microplastics are floating in the air everywhere, indoors, outdoors, in cities, and even in remote places like Antarctica, with tiny plastic fibers being the most common type found. Since we're breathing this stuff in daily, early research links it to lung inflammation, cell damage, and metabolic problems, though scientists say we still need more studies to understand exactly how much exposure is harmful and over what timeframe.

Understanding the dynamics and implications of airborne microplastics in atmosphere

AI summary · Read the abstract

Researchers reviewed the sources, distribution, and health risks of airborne microplastics, finding that fibrous particles raise particular concern due to prolonged residence in organisms, while smaller particles remain understudied, and calling for standardized sampling methods and long-term epidemiological studies to fill critical knowledge gaps.

A Research on Microplastic Presence in Outdoor Air

AI summary · Read the abstract

Researchers measured microplastic concentrations in outdoor air, confirming that these tiny plastic particles are airborne pollutants present in open environments in significant quantities. This finding suggests that humans may inhale microplastics on a routine basis, adding atmospheric exposure to the dietary routes already documented in food and water.

Atmospheric Microplastics in Outdoor and Indoor Environments

AI summary · Read the abstract

Researchers reviewed microplastic contamination across outdoor and indoor atmospheric environments, finding that microplastics are pervasive in both settings and that indoor sources — including synthetic textiles and furnishings — contribute meaningfully to inhalation exposure risks for humans.
