The Peril of Plastics: Atmospheric Microplastics in Outdoor, Indoor, and Remote Environments
AI summary Read the abstract
This review surveys the current state of knowledge about microplastics suspended in the atmosphere, covering outdoor, indoor, and remote environments. Researchers found that airborne microplastics are far more widespread than previously recognized, with fibers from textiles and vehicle tire wear being major sources. The study highlights that atmospheric transport can carry microplastics to even the most remote locations on Earth, and that inhaling these particles poses potential health concerns.
The increasing commercial, industrial, and medical applications of plastics cannot be halted during the coming years. Microplastics are a new class of plastic pollutants which have emerged as escalating environmental threats. The persistence, effects, and removal of MPs present in soil, water, and numerous organisms have become an important research field. However, atmospheric microplastics (AMPs), which are subcategorized into deposited and suspended, remain largely unexplored. This review presents the recent developments and challenges involved in fully understanding suspended and deposited AMPs. The evaluation of indoor suspended MP fibers needs to be critically investigated to understand their implications for human health. Furthermore, the transportation of AMPs to isolated locations, such as cryospheric regions, requires immediate attention. The major challenges associated with AMPs, which have hindered advancement in this field, are inconsistency in the available data, limited knowledge, and the lack of standardized methodologies for the sampling and characterization techniques of AMPs.

Microplastics in the urban atmosphere: Sources, occurrences, distribution, and potential health implications
AI summary Read the abstract
This review summarizes research on airborne microplastics in cities, finding that indoor sources like textiles and outdoor sources like traffic-related plastic particles are major contributors. Microplastic concentrations in urban air can be significant, especially in densely populated areas, and people can inhale these particles daily. The health implications of breathing in microplastics are still being studied, but early evidence suggests they may cause lung inflammation and other respiratory problems.
