Atmospheric microplastic composition and concentration from an uncrewed aerial system
AI summary Read the abstract
Researchers collected airborne microplastic samples using an uncrewed aerial system (UAS/drone) and characterized particle composition by shape (filaments and fragments) using Raman microscopy, with blank-corrected counts across multiple sampling locations.
Data files: - Airborne_MP_count.xlsx – This file contains six columns: SampleID, Location, Filaments, Fragments, Filaments_corr, and Fragments_corr. It reports the microplastic particle counts by shape type (Fragments and Filaments), with the _corr columns showing values corrected using the blank controls. - Arvada_20240920_Raman (folder) – Contains 8 csv files generated by Raman microscopy, each including wavenumber and absorbance data. - Arvada_20241002_Raman (folder) – Contains 23 csv files generated by Raman microscopy, each including wavenumber and absorbance data. - Erie_20240919_Raman (folder) – Contains 11 csv files generated by Raman microscopy, each including wavenumber and absorbance data. - Erie_20241003_Raman (folder) – Contains 30 csv files generated by Raman microscopy, each including wavenumber and absorbance data. - Colorado_MP_flights_level_1 – This file contains eight columns: Time (MST), Time (UTC), readingPress, setpoint, outputVal, location, altitude, FLnumber. Time (MST) is the timestamp in second in Mountain Time (local time), Time (UTC) is the timestamp in second in UTC, readingPress is the value read from the pressure sensor, setpoint is the value sent from the microcontroller, outputVal is the value read from the micro blower, location is where the sUAS flights took place, altitude in m above ground level is the hovering altitude of the sUAS, FLnumber is the number identification of the sUAS flight. Small Uncrewed aerial system (sUAS) flight locations: Arvada, Colorado, UAS (39°50’32”N 105°13’09”W) Erie, Colorado, UAS (40°02’41” 104°59’01”W) The polymer identification used Raman microscopy at the Rhode Island Consortium for Nanoscience and Nanotechnology (RIN2), University of Rhode Island, Narragansett, RI, USA.

Temporal Distribution of Airborne Microplastics at an Urban Roadside
AI summary Read the abstract
Researchers conducted a year-long sampling program for airborne microplastics at an urban roadside site in Zhengzhou, China, finding that traffic volume, seasonal variation, and meteorological conditions influenced the temporal distribution and polymer composition of atmospheric microplastics. Micro-Raman spectroscopy identified the dominant polymer types present in traffic-adjacent air.

Atmospheric deposition studies of microplastics in Central Germany
AI summary Read the abstract
Researchers monitored microplastic particles falling from the air in Central Germany over eight months and detected plastic in all wet deposition (rain) samples and half of dry deposition samples, with polypropylene being the most common type. A deeper Raman analysis revealed that standard detection methods may underestimate actual microplastic air pollution by at least ten times, highlighting a large blind spot in atmospheric monitoring.
