“…Natural dust emissions in four size bins are from an offline inventory; 100% of the first bin (0.1 to 1 μm radii) and 38% of the second bin (1–1.8 μm radii) are regarded as fine natural dust. , Fine anthropogenic dust emissions are from the Anthropogenic Fugitive, Combustion and Industrial Dust inventory . We assume that particulate K + was 0.2% of the total fine dust mass. , Sea salt emissions in the accumulated size range (0.1–0.5 μm radii) are from Jaeglé et al; we assume 1% of that mass to be K + . , …”

Levoglucosan has been widely used to quantitatively assess biomass burning’s contribution to ambient aerosols, but previous such assessments have not accounted for levoglucosan’s degradation in the atmosphere. We develop the first global simulation of atmospheric levoglucosan, explicitly accounting for its chemical degradation, to evaluate the impacts on levoglucosan’s use in quantitative aerosol source apportionment. Levoglucosan is emitted into the atmosphere from the burning of plant matter in open fires (1.7 Tg yr–1) and as biofuels (2.1 Tg yr–1). Sinks of atmospheric levoglucosan include aqueous-phase oxidation (2.9 Tg yr–1), heterogeneous oxidation (0.16 Tg yr–1), gas-phase oxidation (1.4 × 10–4 Tg yr–1), and dry and wet deposition (0.27 and 0.43 Tg yr –1). The global atmospheric burden of levoglucosan is 19 Gg with a lifetime of 1.8 days. Observations show a sharp decline in levoglucosan’s concentrations and its relative abundance to organic carbon aerosol (OC) and particulate K+ from near-source to remote sites. We show that such features can only be reproduced when levoglucosan’s chemical degradation is included in the model. Using model results, we develop statistical parametrizations to account for the atmospheric degradation in levoglucosan measurements, improving their use for quantitative aerosol source apportionment.

“…According to [21], Pb may be originally from yellow and red road markings, and gray paint or anticorrosives. Lead is an important component of bearing alloys [22]. Even the use of leaded gasoline in Russia was prohibited for use in 2002, and its relatively high concentrations can be explained by lead persistence in the environment.…”

For the first time, moss biomonitoring covering the territory of the entire Moscow region, without including Moscow, was performed in 2020. Moss Pleurozium schreberi collected at 156 sampling sites were analyzed using neutron activation analysis and atomic absorption spectrometry. A total of 34 elements were determined in moss samples. Obtained data were compared with the results of the moss surveys performed in the Vladimir and Yaroslavl regions in 2018 and with the data of moss surveys conducted in the Moscow region on a limited number of sampling sites in 2004 and 2014. The Moscow region showed to be more polluted than the Vladimir and Yaroslavl regions. In the the Moscow region, the decrease of the content of the main part of the elements over time was noted. Trace elements emission sources were identified and characterized using factor analysis. Contamination Factor, Pollution Load Index, and Ecological Risk were calculated to assess the level of the region contamination and elements effect on human health. In general, the Moscow region can be characterized as unpolluted to moderately polluted with a low ecological risk of human exposure. The cities satellites around Moscow were determined to experience particular environmental stress, even in the period of the COVID-19 restrictions.

Every aircraft leaves tire wear particles on the ground of airports at take-off and landing. To maintain good grip properties, the pavement must be regularly cleaned up. The gathered Tire Wear Airstrip Particles (TWAP) normally get disposed by burning. As they are very similar to rubber powder the question is if they might be used as a secondary raw material to keep them longer in the loop in the sense of circular economy. In this study TWAP gathered by the cleaning of the runway of an airport in Germany are compared to ambient ground rubber powder from truck tire treads. Both are analyzed microscopically with regard to their morphology, particle size distribution and chemical composition by calcination with following elemental characterization of the ash by Energy-Dispersion-X-ray Analysis (EDS) in the Scanning Electron Microscope (SEM) and Thermal Gravimetric Analysis (TGA). The particle size distribution of TWAP is broader than rubber powder containing also much smaller particles. The mineral content is about 60% of the gathered TWAP. These minerals can be residues of the pavement or break wear and to a smaller amount from the rubber ingredients. Although the TWAP on their own are similar to rubber powder, the impurities they contain may have an impact with regard to potential applications.
