“…In addition to dust originating from outcrops, stone quarries and soils, the δ 26 Mg value of precipitation can also be affected by industrial operations. We have previously documented that continued open‐pit coal mining and large‐scale land‐use changes driven by heavy industry and extensive farming in Central Europe result in periodic but irregular trends in the isotope composition of other environmentally relevant elements in atmospheric deposition: for short periods of time (3–8 days), HYSPLIT analysis of air‐mass trajectories revealed a wind‐direction control of the 206 Pb/ 207 Pb, 66 Zn/ 64 Zn and 65 Cu/ 63 Cu isotope ratios in atmospheric deposition (Cimova et al, 2016; Novak et al, 2016; Voldrichova et al, 2014). True seasonality was observed only for 34 S/ 32 S ratios, related to seasonality in coal burning by thermal power plants (higher demand for electricity in winter; Novak et al, 1995).…”

Data on temporal variability in Mg isotope ratios of atmospheric deposition and runoff are critical for decreasing the uncertainty associated with construction of isotope mass balances in headwater catchments, and statistical evaluation of isotope differences among Mg pools and fluxes. Such evaluations, in turn, are needed to distinguish between biotic and abiotic contributions to Mg 2+ in catchment runoff. We report the first annual time-series of δ 26 Mg values simultaneously determined for rainfall, canopy throughfall, soil water and runoff. The studied 55-ha catchment, situated in western Czech Republic, is underlain by Mg-rich amphibolite and covered by mature spruce stands. Between 1970 and 1996, the site received extremely high amounts of acid deposition and fly ash form nearby coal-burning power plants. The δ 26 Mg values of open-area precipitation (median of À0.79‰) at our study site were statistically indistinguishable from the δ 26 Mg values of throughfall (À0.73‰), but significantly different from the δ 26 Mg values of soil water (À0.55‰) and runoff (À0.55‰). The range of δ 26 Mg values during the observation period decreased in the order: open-area precipitation (0.57‰) > throughfall (0.27‰) > runoff (0.21‰) > soil water (0.16‰). The decreasing variability in δ 26 Mg values of Mg 2+ from precipitation to soil water and runoff reflected an increasing homogenization of atmospheric Mg in the catchment and its mixing with geogenic Mg. In addition to atmospheric Mg, runoff also contained Mg mobilized from the three major solid Mg pools, bedrock (δ 26 Mg of À0.32‰), soil (À0.28‰), and vegetation (À0.31‰). The drought of summer 2019 did not affect the nearly constant δ 26 Mg value of runoff. Collectively, our data show that withincatchment processes buffer the Mg isotope variability of the atmospheric input.

“…Air pollution from anthropogenic sources is an increasing environmental concern for mountain countries, which typically have developing economies based on the exploitation of natural resources and rapid natural to urban land conversion 35,36 . Evidences of the presence of chemical species in the snow derived from air pollution have been reported in the Himalayas [37][38][39] , Tibetan plateau 40,41 , Central European mountains 42 and Alps 43 . However, few studies have aimed at determining the impact of these contaminant emissions on natural snow reservoirs in the Andean mountains 15,44,45 .…”

The chemical composition of snow provides insights on atmospheric transport of anthropogenic contaminants at different spatial scales. In this study, we assess how human activities influence the concentration of elements in the Andean mountain snow along a latitudinal transect throughout Chile. The concentration of seven elements (Al, Cu, Fe, Li, Mg, Mn and Zn) was associated to gaseous and particulate contaminants emitted at different spatial scales. Our results indicate carbon monoxide (CO) averaged at 20 km and nitrogen oxide (NOx) at 40 km as the main indicators of the chemical elements analyzed. CO was found to be a significant predictor of most element concentrations while concentrations of Cu, Mn, Mg and Zn were positively associated to emissions of NOx. Emission of 2.5 mm and 10 mm particulate matter averaged at different spatial scales was positively associated to concentration of Li. Finally, the concentration of Zn was positively associated to volatile organic compounds (VOC) averaged at 40 km around sampling sites. The association between air contaminants and chemical composition of snow suggests that regions with intensive anthropogenic pollution face reduced quality of freshwater originated from glacier and snow melting.

“…The fog pathway should definitely be accounted for in real deposition flux studies, although fog occurrence in the CR has decreased significantly over the last sixty years [203]. The chemistry of rime (as a part of horizontal deposition) has been studied recently at 10 regional mountain-top sites in the CR [204][205][206][207], nevertheless the contribution of rime to atmospheric deposition has been unclear thus far. Improving ambient air quality and decreasing atmospheric deposition have also been demonstrated by long-term nationwide biomonitoring, including analyses of mosses and tree bark [208][209][210][211][212][213].…”

Based on an analysis of related core papers and reports, this review presents a historical perspective on ambient air pollution and ambient air quality development in the modern-day Czech Republic (CR) over the past seven decades, i.e., from the 1950s to the present. It offers insights into major air pollution problems, reveals the main hot spots and problematic regions and indicates the principal air pollutants in the CR. Air pollution is not presented as a stand-alone problem, but in the wider context of air pollution impacts both on human health and the environment in the CR. The review is arranged into three main parts: (1) the time period until the Velvet Revolution of 1989, (2) the transition period of the 1990s and (3) the modern period after 2000. Obviously, a major improvement in ambient air quality has been achieved since the 1970s and 1980s, when air pollution in the former Czechoslovakia culminated. Nevertheless, new challenges including fine aerosol, benzo[a]pyrene and ground-level ozone, of which the limit values are still vastly exceeded, have emerged. Furthermore, in spite of a significant reduction in overall emissions, the atmospheric deposition of nitrogen, in particular, remains high in some regions.
