Microplastic atmospheric pollution in an urban Southern Brazil region: What can spider webs tell us?
AI summary Read the abstract
Researchers used spider webs as a passive sampling tool to monitor airborne microplastic pollution across urban areas in southern Brazil. They found microplastics in webs from all sampling locations, with fibers being the most common type, reflecting contributions from synthetic textiles. The study demonstrates that spider webs can serve as a simple and effective method for tracking atmospheric microplastic contamination in cities.
Airborne Microplastic Pollution in a Highly Urbanized City: Occurrence, Characteristics, Human Exposure and Potential Risks
AI summary Read the abstract
Airborne microplastic monitoring in Guangzhou found concentrations averaging 2.5 particles/m³, with fiber-form MPs from synthetic textiles dominant and levels highest near high-traffic areas, translating to estimated human inhalation of 4,100–12,180 particles per year. Quantifying inhalation exposure in megacities is a public health priority given emerging evidence that airborne MPs deposit in lung tissue and may drive respiratory inflammation.
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.
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.
