Survey of atmospheric microplastics research published 2015+, covering 26 studies across Asia, Europe, Americas
Microplástico é toda partícula com diâmetro inferior a 5 mm composta por plástico, ou outros polímeros artificiais, dispersa no ambiente. O plástico e outros polímeros estão em praticamente toda a cadeia de produção industrial. O material tem alto potencial poluidor em todos os ecossistemas, pois não se degrada, apenas se fragmenta. Este estudo objetiva a divulgação científica sobre pesquisas de microplásticos na atmosfera, abordando os métodos e técnicas para a coleta e os principais protocolos laboratoriais utilizados. Foi feito um levantamento nos portais da CAPES e Google Acadêmico® na busca por pesquisas envolvendo microplásticos na atmosfera (artigos, teses e dissertações). As publicações disponíveis começaram a surgir no ano de 2015, distribuídas pelos continentes: doze na Ásia; dez na Europa e quatro nas Américas.

Atmospheric deposition of microplastics: a sampling and analytical method including the associated measurement uncertainties
AI summary Read the abstract
Researchers developed a tailored analytical chain for atmospheric microplastic sampling — including collection, processing, and optical microscopy-based analysis — and applied it to quantify atmospheric deposition of microplastics and assess the atmosphere as a vector of global microplastic distribution.
A review of atmospheric microplastics pollution: In-depth sighting of sources, analytical methods, physiognomies, transport and risks
AI summary Read the abstract
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.

Status and prospects of atmospheric microplastics: A review of methods, occurrence, composition, source and health risks
AI summary Read the abstract
This review summarized the sampling methods, occurrence, composition, sources, and health risks of atmospheric microplastics. Researchers found that airborne microplastics are detected both indoors and outdoors, with fibers being the most common shape, and that inhalation represents an important but understudied exposure pathway. The study suggests that atmospheric transport plays a significant role in the global distribution of microplastic pollution.
