“…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.

“…The reported δ 65 Cu variation of the atmospheric precipitation (including snow, rime and rainwater) was −1.44 ~ +0.40‰, averaging −0.12‰ [19,82]. More studies are expected to map the regional and global atmospheric Cu isotope signatures and to investigate the mechanisms fractionating Cu isotopes in atmospheric processes.…”

Copper (Cu) is a transition metal and an essential micronutrient for organisms, but also one of the most widespread toxic inorganic contaminants at very high content. The research on Cu isotopes has grown rapidly in the last decade. Hitherto, a large number of studies have been published on the theoretical fractionation mechanisms, experimental data and natural variations of Cu isotopes in variable environments and ecosystems. These studies reported a large variation of δ65Cu (−16.49 to +20.04‰) in terrestrial samples and showed that Cu isotopes could be fractionated by various biogeochemical processes to different extent. Several papers have previously reviewed the coupling of Cu and Zn isotope systematics, and we give here a tentative review of the recent publications only on Cu isotopesin variable surface repositories, animals and human beings, with a goal to attract much attention to research on Cu (and other metals) behaviors in the environment and biological systems.

“…Lead isotope analysis was performed with a mass spectrometer with inductively coupled plasma (ICP MS X-series, Thermo Fisher Scientific). Detailed analytical methods and sample processing are described in Čimová et al (2016), Bohdálková et al (2012) and Novák et al (2016).…”

“…The considerable between-site variability of winter deposition values described in Čimová et al (2016), Bohdálková et al (2012) and Novák et al (2016) led us to attempt to classify relative pollution load levels into classes according to pollution input amounts. To evaluate the degree of relative pollution load at each individual site i we used the following equations:…”

Bohdálková L., Hruška J. 2017: Spatial and temporal trends in winter deposition of Pb, Be, Cu and Zn in selected mountain areas of Central Europe -Beskydy, 10 (1,2): 87-98Atmospheric depositions of trace metals have been the focus of attention because of their potential toxicity to living organisms. In this paper, winter deposition rates of Pb, Be, Cu and Zn collected from 2009 to 2011 at 10 mountain-top localities in the border area of the Czech Republic were compared and summarized. Across the sites there were up to 7-8fold differences in Pb, Be and Zn deposition rates, and up to threefold differences in their Cu deposition rates. In all cases, rime contained higher amounts of Pb, Be, Cu and Zn compared to snow. More than 92 % of Pb, Cu and Zn occured in soluble (bioavailable) form, whereas only 34 % of Be was in soluble form. Recent trace metal concentrations in precipitation considerably decrease compared to those measured during the period of the highest atmospheric emissions in the 1980s. The industrial region in the northeast of the Czech Republic experienced moderate levels of Pb air pollution, while atmospheric Pb inputs in the rest of the country as well as overall inputs of Cu, Zn and Be were low, representing a low threat to human and ecosystem health. Between-site differences made it possible to classify sites into three categories according to their level of pollution load. A previously-mentioned north-south pollution gradient between the industrial north and rural south of the country was not observed. Sites in the northwest and in the south were among those with the lowest pollution loads. On the other hand, sites in the northeast were the most polluted due to their location near the industrial regions of southern Silesia (Poland) and Ostrava.
