“…The features of microplastics in snow reported to date differ considerably among the reported descriptions 3,17,[20][21][22][23][24][25][26][27][28] . Although Zhang and others pointed out in their review article 19 that this diversity might be attributable more to differences in sampling and analytical methods used than to actual regional differences, we strove to extract meaningful information by comparing our results with those reported from earlier studies.…”

“…Pioneering research conducted by Bergman and others 14 brought to light the presence of great numbers of fine microplastics in snow from Europe and the Arctic, and highlighted atmospheric transport and deposition as notable pathways for MPs meriting more research. Subsequently, several studies have confirmed that MP pollution in snow spreads worldwide 3,17,[20][21][22][23][24][25][26][27][28] . Nevertheless, because of limited data, little is known about the features and pathways of microplastics in snow.…”

Snowfall is regarded as a carrier of airborne microplastics (MPs). Deposited snow can function as a temporary reservoir for atmospheric MPs. Nevertheless, knowledge and understanding of microplastics in snow remain sparse. This study investigates the abundance, composition, size, and shape of microplastics in snow specimens from various nature preservation areas and also from urban sites in Hokkaido. Various polymeric-type microplastics with mostly fragment shapes were detected among the specimens. Results demonstrated that MP abundance generally decreases concomitantly with increasing remoteness of sampling sites. Observed features of microplastics at different locations and their relation to geographical settings have indicated that the ubiquitously observed fine particles (mainly alkyd, ethylene-vinyl acetate, and polyethylene) are attributable to long-distance atmospheric transportation, while the rubber and larger particles especially found near highways and cities are from local sources of plastic.

Snowfall is regarded as a carrier of airborne microplastics (MPs). Deposited snow can function as a temporary reservoir for atmospheric MPs. Nevertheless, knowledge and understanding of MPs in snow remain sparse. This study investigates the abundance, composition, size (> 30 µm), and shape of MPs in snow specimens from various nature preservation areas and also from urban sites in Hokkaido. Various polymeric-type MPs with mostly fragmentary shapes were detected among the specimens. More than half of MPs were in the smallest size class (30–60 µm), implying the presence of more MPs below the limit (< 30 µm). Concentrations of MPs ranged from 1.5 × 102 to 4.2 × 103 particles/L. The results demonstrated that microplastic abundance generally decreases concomitantly with increasing remoteness of sampling sites. Observed features of MPs at different locations and their relation to geographical settings have indicated that the ubiquitously observed fine particles (mainly alkyd, ethylene–vinyl acetate, and polyethylene) are attributable to long-distance atmospheric transportation, whereas the rubber and larger particles especially found near highways and cities are from local sources of plastic. Taken together, these findings suggest important implications for elucidating the nature and distribution of atmospheric MPs.

“…Plastics with sizes between 1 μm and 5 mm are recognized as microplastics. [1][2][3][4] Recently, several reports have revealed the distribution of microplastics in nature, for example in oceans, [5][6][7] rivers, [8][9][10][11] lakes, 12,13) snow [14][15][16] and soil. 17) Microplastics in the environment have been detected in different forms (spheres, fragments, fiber, film, foam, pellets, etc).…”

Engineered microplastics are vital mimics of natural microplastics for application in many research areas aimed at solving environmental pollution. Here, we demonstrate the fabrication of engineered microplastics using 1 MeV protons with a full penetration depth to effectively detach engineered microplastics from a substrate. The microplastic patterns in this work were made in an epoxy-based polymer (SU-8) spin-coated on a silicon (Si) substrate by employing a proton beam writing technique at the Shibaura Institute of Technology. It was found that the SU-8 microplastic was efficiently detached from the Si substrate. This fabrication approach also enables the SU-8 microplastic to be stored on the Si substrate before use.
