Long-term monitoring of data ambient mercury (Hg) on a global scale to assess its emission, transport, atmospheric chemistry, and deposition processes is vital understanding the impact Hg pollution environment. The Global Mercury Observation System (GMOS) project was funded by European Commission (http://www.gmos.eu) started in November 2010 with overall goal develop coordinated observing system monitor scale, including large network ground-based stations, ad hoc periodic oceanographic...
Abstract. The atmospheric deposition of mercury (Hg) occurs via several mechanisms, including dry and wet scavenging by precipitation events. In an effort to understand the cycling seasonal depositional characteristics Hg, samples were collected for approximately 5 years at 17 selected GMOS monitoring sites located in Northern Southern hemispheres framework Global Mercury Observation System (GMOS) project. Total (THg) exhibited annual patterns Hg samples. Interannual differences total are...
Research has focused on the effect of sulphate and nitrate atmospheric deposition river water chemistry in Baikal region. During long-term monitoring it was ascertained that anthropogenic SO2 NOx plumes emitted from regional coal Power Plants (PPs) cause extra Pereemnaya River basin is located 100–150 km away emission sources. As a result, average concentrations are 2–3 times higher than those Lake Baikal, whilst total mineralisation approximately 3 lower. Because acidity basin, pH value...
The present study is aimed at the development of a novel empirical base for application to ground-based astronomical telescopes. A Weather Research and Forecasting (WRF) model used description atmospheric flow structure with high spatial resolution within Baikal Astrophysical Observatory (BAO) region. Mesoscale vortex structures are found boundary layer, which affect quality images. results simulations show that upward air motions in lower atmosphere suppressed both above cold surface Lake...

This paper analyzes the results of automatic (in situ) recording regional transport pollutants from large coal-fired thermal power plants in atmospheric boundary layer above southern basin Lake Baikal. Due to high stacks (about 200 m), emissions rise altitudes several hundreds meters and spread over long distances their source by tens kilometers. The continuous monitoring atmosphere Baikal on top coastal hill (200 m lake) revealed a number sulfur oxides nitrogen form high-altitude plumes...
The measured concentrations of inorganic pollutants, such as ozone (2015–2018), sulfur, and nitrogen oxides (2012–2018) at air monitoring sites in the south Eastern Siberia were sampled, following passive sampling method, analyzed. spatial inhomogeneity atmospheric gas is presented. concentration lower urban areas than those rural background level. However, sulfur oxide are higher atmosphere over city site. seasonal dependence was determined using its maximum (March–April) minimum...
Abstract. We present long-term (2011 2021) data on air mercury monitoring that was started within the GMOS (Global Mercury Observation System) project (2011-2015) at Listvyanka station located shore of Lake Baikal, Siberia. Monitoring shows an obvious seasonal variation in background concentration air, which increases cold season and decreases warm season. Short-term anomalies are associated with wind carrying from industrial areas where several large coal-fired power plants (Irkutsk...
This article presents the results of automatic monitoring concentrations gaseous impurities sulfur and nitrogen oxides in ground-level atmosphere urban rural areas Southern Baikal region (East Siberia, Russia). The study was conducted from 2020 to 2023 at Irkutsk station Listvyanka located a distance 70 km each other. We calculated main statistical characteristics variations dioxide determined nature variability their on various time scales: annual, weekly, daily. Annual variabilities...
The GMOS (Global Mercury Observation System) project has the overall goal to develop a coordinated observing system monitor mercury on global scale. Here we present long-term (2011–2020) air monitoring data obtained at Listvyanka station located shore of Lake Baikal, Siberia. shows obvious seasonal variation background concentration in air, which increases cold and decreases warm season. short-term anomalies are associated with wind carrying from industrial areas where several big coal-fired...
The results of long-term studies (1995-2017) the physical properties and chemical composition atmospheric aerosol in Baikal region are considered. These important for understanding role atmosphere formation quality waters its inflows. Over past two decades, Limnological Institute SB RAS (Irkutsk, Russia) have conducted various joint characteristics with Russian foreign groups. composition, biological component, size distribution, spatial distribution sources over lake were investigated....
The mass development of the phototrophic under-ice community is an interesting phenomenon known for Arctic Ocean as well some rivers and freshwater lakes, including Lake Baikal. Species composition productive characteristics phytoplankton in Baikal are studied. During blooming, endemic dinoflagellate Gymnodinium baicalense var. minor Antipova can create more than half annual primary production. However, there still many questions to be answered regarding factors limiting abundance...

Abstract Ozone is one of the most toxic admixtures in troposphere. Therefore, it among main pollutants and its concentration monitored. This work represents an overview continuous measurements ozone content troposphere on territory Russia throughout 2021 carried out initiative scientific educational institutions at 17 stations different Russian regions. The monitoring results showed that daily average exceeded MPC d.a level during a major part year all observation sites, by factor two or...
Abstract Phytoplanktonic dinoflagellates form colonies between vertical ice crystals during the ice-melting season in Lake Baikal, but how plankton survive freezing conditions is not known. Here we show that phytoplankton produces large amounts of dimethylsulfoniopropionate (DMSP), which best-known as a marine compound. Lake-water DMSP concentrations spring are comparable with those oceans, and colony water exhibits extremely high concentrations. concentration surface correlates density...
