Does microplastic really represent a threat? A review of the atmospheric contamination sources and potential impacts
AI summary Read the abstract
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.
Microplastics (MPs) are regarded as one of the major atmospheric contaminants that have gained wide attention across the globe in the current dispensation. Airborne MPs have been collected in atmospheric fallouts, in indoor and outdoor air as well as along roadways and indoor dust. The most dominating constituent shapes and forms of identified airborne MPs are fibers and synthetic textiles, respectively. With the breathing mechanism as a spontaneous practice for survival, the inhalation of airborne MPs is an inevitable deal. The level of toxicity of MPs to organisms stems from its physiochemical speciation. The smaller size and almost weightless nature make it possible to suspend in the atmosphere and be inhaled and create potential health problems. Nonetheless, the data available concerning the presence of airborne MPs and its environmental and human health impacts is limited. In this review, we extensively discuss the rigorous and suitable methodologies adopted for the analysis of airborne MPs in previous studies. The characteristics and sources of airborne MPs, the potential health impacts on humans, and some mitigating measures have also been discussed thoroughly.

AI summary Read the abstract
This review explores the emerging concern that airborne microplastics can be inhaled by humans, potentially causing adverse effects on the respiratory system. Researchers compiled available data on the concentration, size, shape, and chemical composition of microplastic particles found in urban air. The findings suggest that airborne plastic debris represents a largely understudied class of air pollutant with potential implications for human health.
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.
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.
