Uranium in Water of the Baikal Ecosystem
Pleiades Publishing Ltd - 2023
Tóm tắt
Analysis of the distribution of uranium concentrations in the water of conjugated components of the Baikal ecosystem (the water of Lake Baikal and its tributaries, headwaters of the Angara River, and groundwater from the wells drilled on Olkhon Island, and in the southwestern coastal part of Lake Baikal) has been carried out. The essential differences of the maximum uranium concentrations in groundwater of Lake Baikal and its inflows and the close average and median values of uranium in the water of Lake Baikal and the Angara River source were determined. The data obtained on the uranium distribution fix the influence of geological and geochemical peculiarities of the structure of the Baikal ecosystem and its surroundings and the climatic and catastrophic (earthquakes, seismic geodynamic activation, etc.) events that take place in the region. The changes in the uranium concentration in the water of Lake Baikal in relation to the seismic process were analyzed on the example of strong earthquakes (M ≥ 5) in the Lake Baikal area.
