“…the Karkonosze granites, so far is poorly studied. The occurrence of such waters is evidenced by interesting recent finds of Na-(Ca)-Cl radon cold mineral water in two springs at Albrechtice near Frýdlant (Czechia) on the westernmost edge of this crystalline complex (Goliáš et al, 2014(Goliáš et al, , 2022.…”

A long-term (2004-2021) study of the chemical composition of thermal waters in the Jelenia Góra geothermal system provided information on a wide set of components. The subject of the present study is the geochemistry of germanium (Ge), which occurs in concentrations ranging from 2.7 to 6.3 µg/L in the waters studied. Interpretation of a set of 46 chemical analyses identified relationships between germanium and other elements in thermal waters from individual intakes. In the old thermal waters of Cieplice and Karpniki of deep circulation, germanium is derived from silicates and its concentration is controlled by the solubility of Ge-bearing quartz with an average Ge content of 1.5 µg/g. The source of germanium in the deep old thermal water at Staniszów is mainly sulphides, most likely arsenopyrite, but the secondary contribution of Ge from silicates (biotites, amphiboles) should not be ignored. The mineral phase, responsible for controlling Ge activity in this water, cannot yet be identified. The shallow thermal waters at Cieplice, which are a mixture of old thermal waters and modern waters, differ from the deep waters. Germanium in shallow waters probably is derived from silicates, but owing to mixing, there are no chemical equilibrium conditions; the concentration of Ge is determined by the dynamic equilibrium of the mixed water components. The modern water of intake no. 2 (Cieplice) differs from other shallow waters and also shows similarities to the Staniszów water. The germanium in the no. 2 water probably comes mainly from ferromagnesian minerals (biotite, amphiboles), although the influence of sulphides cannot be excluded. The relationships of germanium to other elements, including the Ge/Si ratio, appear to be effective indicators of hydrogeochemical conditions. Thermal waters from the different locations show both similarities and differences in chemical composition,especially of minor and trace components. At the present, still weak stage of recognition, the Jelenia Góra geothermal system can be treated as an area of occurrence of local systems responsible for the quantity and quality of thermal waters in individual intakes.

“…The water in these areas is characterized by low mineralization (below 200 mg/L), along with elevated levels of uranium. Additionally, there is a prevalence of manganese over iron, temperatures in the range of 5 and 12°C, an acidic pH, and a season-dependent high oxidation-reduction potential [ 23 ]. Some studies demonstrate that the ability of microorganisms to accumulate manganese leads to their higher resistance to stress conditions and helps in the catalytic detoxification of ROS [ 24 ].…”

Radon springs, characterized by their high concentrations of radon gas (Rn222), are extreme environments with unique physicochemical conditions distinct from conventional aquatic ecosystems. Our research aimed to investigate microbial life in radon springs, focusing on isolating extremophilic bacteria and assessing their resistance to adverse conditions. Our study revealed the prevalence of Actinomycetia species in the radon spring environment. We conducted various tests to evaluate the resistance of these isolates to oxidative stress, irradiation, desiccation, and metal ion content. These extremophilic bacteria showed overall higher resistance to these stresses compared to control strains. Lipidomic analysis was also employed to provide insights into the adaptive mechanisms of these bacteria which were found mainly in the correlations among individual clusters and changes in content of fatty acids (FA) as well as differences between content and type of FAs of environmental isolates and type strains.
