Full paper (RU) Evgeniia V. Domrocheva & Elena V. Zippa Abstract. This paper discusses N2-thermal waters of the Baikal Rift Zone, enriched in various elements, including Na, SO4, F and a number of trace elements (Sr, Br, Li, Al etc.). Temperature, alkaline conditions and oxidation-reduction processes affect the solubility and stability of compounds, determining their migration…

What is in defrosted Russian Arctic ice?
Carbon deposits in thawing permafrost include widely reported methane gases released as bubbles and present in craters across Siberia. Scientists wanted to find out more about the greenhouse emissions and what was in the defrosted ground ice including dissolved organic matter (DOM) and particulate organic matter (POM). They studied four locations across the Russian arctic…
Inspecting climate, chlorine and carcinogens in southern Baikal’s water
248,000 water samples between 2011 and 2022 were recently investigated by researchers at the East-Siberian Institute of Medical and Ecological Research, in Angarsk. Lake Baikal is the world’s largest freshwater lake. It is a UNESCO protected site, also protected in Russian national legislation. Chemical engineering and agro-industrial sites in the region also access the water,…
Climate Change and organic carbon in Rostov soils
Research has shown that there is an accumulation limit for organic carbon in Chernozem (black) soils, resulting in carbon emissions once that limit has been reached. Agricultural management practices can include crop rotation, fallowing, residue management and fertilisation to counter the less carbon-rich soils as they arise. The researchers previously studied a 40 year period…
Highway to bottom sediment – heavy metals in the Russian Far East waters
Heavy metal pollution in Peter the Great Bay and Lake Khanka affects both biological organisms and accumulating in bottom sediments (BS) of both freshwater and seawater. Russian chemists ecided to find out more about the impact on the surrounding ecology by analysing each heavy metal phase, how it appears, what it does and where it…
Exploring the ‘carbon polygon’ of Ladoga
Sustainable soil management (SSM) initiatives review organic matter in soil and carbon sequestration to understand how best to mitigate carbon and methane emissions, improving mitigation of climate change. In Russia, the government established a ‘Carbon Polygons’ project assessing and monitoring carbon in different ecosystems and biomes, especially boreal forest regions. The researchers wanted to assess…
Measuring methane from the Russian Arctic shelf
CO2 (carbon dioxide) are widely publicised but CH4 (methane) emissions are less known. These more potent methane emissions in the atmosphere are also caused by either natural or anthropogenic sources. When oxidised, CH4 leads to the formation of CO2 emissions in atmospheric ozone. Studies of land and water sources of emissions are more widely known….
Digging deeper and deeper into the Lake Chany basin
Lake Chany in Western Siberia has historically been a shallow lake, approximately 2 metres deep and a 2.2 thousand km2 area. It is saline which is similar to other lakes in the region due to intensive evaporation after rain and run off. This theoretically increases the affect of climate change in water levels and surrounding…
Less fizz, more plants – acids and eutrophication in Arctic lakes
Russian researchers identified acidification of lakes during 1990s in Murmansk, Karelia, Archangelsk and Vologda regions and found up to 5% of lakes have acidification due to human causes in humid areas of European Russia and West Siberia. Nornickel was identified as the main contributor of sulphur dioxide SO2 in Kola and Norilsk areas. However since…
Salt on the move in the permafrost
Researchers at Skoltech wanted to understand more about the effect of pressure and temperature on salt distribution in permafrost that contains hydrates and permafrost that doesn’t. Existing research does not model salt diffusion and transportation in permafrost thawing. They simulated experiments reproducing the degrading permafrost in laboratory conditions by changing the temperature and pressure whilst…
