HYDROCHEMISTRY OF THE TYRMA RIVER
Regional problems, 2021 The spatial-temporal dynamics of the dissolved substances content in the Tyrma River water and in its tributaries have been studied by the author. It was found great differences in the values of mineralization and concentrations of HCO3-, Ca2+, Mg2+ and Fe, due to natural conditions of the territory.

Validation of hydrogeochemical databases for problems in deep geothermal energy
Geothermal Energy, 2018 Hydrogeochemical modelling has become an important tool for the exploration and optimisation of deep hydrogeothermal energy resources. However, well-established software and model concepts are often run outside of its temperature, pressure, and salinity ...

Production of redox-active-reactive filter material from charcoal
Next MaterialsThe surficial and textural features of a pyrogenic carbonaceous material (charcoal) was modulated with acidic Piranha solution (i.e., 1:3 30% H2O2 to H2SO4) to produce a redox-active adsorbent for the simultaneous adsorption and reduction of Cr(VI) in ...

Journal of Fish Biology, EarlyView.Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods

Responses of Water Quality Parameters to El Niño in the Curuá‐Una Reservoir, Amazon Basin
CLEAN – Soil, Air, Water, Volume 54, Issue 10, October 2026.ABSTRACT The El Niño phenomenon in the Amazon is associated with extreme drought and lower atmospheric humidity, leading to environmental disturbances, such as wildfires and decreased river levels. An exceptionally intense El Niño occurred between 2015 and 2016, reaching historic magnitudes.
