A review of analytical methods and models used in atmospheric microplastic research

Dissecting giant hailstones: A glimpse into the troposphere with its diverse bacterial communities and fibrous microplastics

“…Many of the other particles could also be man-made; however, we could not resolve them using Raman spectroscopy. This technique suffers from drawbacks such as luminescence (the main limiting factor in this type of spectroscopy), which could be inherent because of the additives (Luo et al, 2022) or a consequence of the electronic modification of the material under study. The latter is a consequence of degradation mechanisms in the atmosphere.…”

Weathering and degradation of polylactic acid masks in a simulated environment in the context of the COVID-19 pandemic and their effects on the growth of winter grazing ryegrass

“…These microplastics may have come from the mixing of airborne microplastics during production and packaging. According to statistics, the colors of MPs in the air vary, including blue, red, yellow, green, and other colors [28] , [30] , and they have both a large density and quantity. Zhang et al [51] showed that even in dormitories (9.9 10 3 MPs/m 2 /d) and offices (1.8 10 3 MPs/m 2 /d), there is a high abundance of MPs in the air.…”

Ecological and human health risks of atmospheric microplastics (MPs): a review

“…Atmospheric MPs had been identified and quantified by macroscopic, microscopic, and spectroscopic techniques 44,45,46 . MPs identified by physical characterization methods such as vision and microscopy are limited in size.…”

“…43 Atmospheric MPs have been identied and quantied by macroscopic, microscopic, and spectroscopic techniques. [44][45][46] The size of MPs detectable by physical characterization methods such as vision and microscopy is limited. Although physical characterization methods such as infrared spectroscopy and Raman spectroscopy are more conducive to identifying common MPs with smaller sizes (down to 50 nm), they cannot identify the color and shape of MPs.…”
