This study presents the determination and comparison of isotopic compositions Hg in sediments, plankton, roach, perch two freshwater systems Lake Baikal−Angara River aquatic ecosystem: man-made Bratsk Water Reservoir contaminated by from a chlor-alkali factory noncontaminated Baikal. Isotopic ratios biota exhibit both significant mass-independent fractionation (MIF) (Δ199Hg 0.20 to 1.87‰) mass-dependent (MDF) (δ202Hg −0.97 −0.16‰), whereas sediments high MDF −1.99 −0.83‰) but no MIF. δ15N...
Abstract Currently, many countries of the world experience drinking water scarcity. In this aspect, Russia has an advantageous position, having on its territory Lake Baikal, largest storage fresh water. UNESCO declared Baikal as a World Heritage Site whose state scientists from and other monitor study. An analysis literature author information about aquatic ecosystem shown 70-year invariability macroelement composition only outflow, Angara River. The River constant calcium bicarbonate is...
Abstract Analysis of the ion composition in water Baikal ecosystem (Lake Baikal, Angara River estuary and 35 tributaries) spring autumn 2018 has shown that from maintains low mineralization (94-98 mg/l) corresponds to calcium bicarbonate composition. The average chemical is within range minimum-maximum values water. In some tributaries, two-three times higher compared estuary. intermediates studied tributaries. Microbiological studies have number hygiene indicator microorganisms tributaries...
Studies of the Angara River source from March 2017 to April 2020 provided monthly monitoring quality waters in Lake Baikal. The water based on hygiene indicator bacteria indicated its correspondence standards for assessment surface waters, except two samples taken May 2018 and July 2019 (exceeding number enterococci). data microorganisms were generally comparable results investigations pelagic lake significantly lower than values main tributaries lake. revealed psychrophilic was mainly equal...
The study was conducted in 2 urbanized areas of the Baikal region Russia. These are cities Shelekhov and Tayshet with their suburbs. Aluminum production has been carried out for over 60 years 5 years. purpose to determine pollution urban soils toxic elements—Al, F, Be, Li, as well Cr, Ni, Pb, so on under influence industrial enterprises (aluminum cable plants, thermal power plants). Also, research effect increased fluorite (F) environment children’s health. Pure aluminum is used much less...
