The results of the exploration of the dynamics of water level in the lake Bolshoy Tambukan for the period of more than 230 years is given. Lake Bolshoy Tambukan is a large deposit of peloids in the south part of Russia. Two periods of development of the lake are revealed: natural and natural-anthropogenic. Currently, there is a catastrophic rise of water in the lake and a decrease in its mineralization below 25 g/l. Data on fluctuations of mineralization and the most significant natural and anthropogenic events ar...

Uranium-238 is a parent radionuclide for several radioactive stable chemical elements, which presence in the therapeutic mud can cause negative consequences for patients. This paper presents the results of the study of the U-238 specific activity in the mud sediment cores of Pelenkino Lake and Bolshoi Tambukan Lake situated in two different geological and hydrological regions in the south of European Russia. The relationship between the U-238 specific activity in the mud, its pH, Eh values and the organic matter c...

Hydrogen sulfide is a gas that is formed in various water bodies due to the flow of sulphate reduction and putrefaction of organic matter of bottom sediments. Hydrogen sulfide can also get in the water of reservoirs and watercourses with wastewater of various industries and farms. In the water objects of fishery and drinking water use concentration normalized, since due to the toxicity of hydrogen sulfide deteriorates the water quality, occur hypoxic effects and death of aquatic organisms, while for ponds with mud...

Terrestrial and submarine mud volcanoes of the Taman Peninsula are confined to the continuation of the Temryuk-Kerch anticline zone. Many of them, especially submarine volcanoes, are characterized by periods of active spontaneous activity. Mud volcanoes are of interest as not only objects that can have a negative impact on the natural environment, but also as sources bringing benefits in the form of erupted mud masses that are used to treat people. Up to this point, the question of the depth and temperature of the...
