“…The Volga River accounts for about 80% of the total surface runoff into the sea. In some high water years, river runoff may be 75% of Beili sea volume [2,3]. Depending on the degree of pollution of the river waters, their contribution to the pollution of the northern ocean is also different.…”

“…In Kashagan in the spring of 2014, an abnormally high concentration of chromium (400 mg/dm³), iron (1672 mg/dm³), and nickel (138 mg/dm³) was found in a sample. The observation area is characterized by initial (background) contamination of copper (1.3 MPC) and vanadium (2)(3)(4)(5)(6). In 2008, a wide area with increased mercury and arsenic, vanadium, and total chromium content was discovered.…”

The article presents the results of chemical analysis for the content of heavy metals in the waters of the fields in the northern part of the Caspian Sea. The content of heavy metals in water is a complex and informative indicator of the degree of water pollution and can be used in environmental monitoring of water bodies. An analysis was carried out on the content of eleven heavy metals at the Kashagan, Kalamkas Kairan and Aktoty deposits for the period from 2006 to 2019. All results were averaged with indication of their minimum, maximum and average values, and were also compared with the MPC of these heavy metals. Among the eleven heavy metals, only one metal is characterized by a content below the MPC, this is barium. The barium content was determined by sweat in all samples, but at the same time they did not exceed the MPC in all samples. A slight excess of the MPC is typical for such metals as cadmium, arsenic and zinc. Almost in all samples, except for one sample, cadmium was found, but at the same time it did not exceed 0.3 MPC. The maximum value was determined in samples from the Kashagan field. Arsenic was found only in 3.4% of samples, mainly in deep-water areas of the Kalamkas field, in which the content did not exceed 1.3 MPC. The zinc content was found in most samples with no excess of more than 0.3 MPC. The rest of the elements are high and highly high in content such as mercury, lead, vanadium, chromium, copper, nickel, and iron. The content of mercury was found in the samples over 1%, but with an excess of 10 to 47 MPC. The content of lead was found in the samples over ten percent, with an excess of 11 to 60 MPC. Vanadium was found in samples of about 20%, with an excess in the range of 2-6 MPC. Chromium was found in most samples with an excess of 3 to 29 MPCs at Kalamkas in 2014 and Kashagan in 2019. Copper content was found in samples of about 90%, with high concentrations at Kashagan in 2006 and 2010 up to 10-38 MPC. Nickel is found in most samples with a level of 0.9-1.1 MPC. The content of iron was found in more than 10 percent of samples with an excess of 15-60 MPC with a decrease of almost 3 times from 2006-2010 to 2011-2019.

“…As a result of the restructuring of the main soil-geochemical parameters with oil pollution, the distribution of organic carbon in the soil changes. In case of oil spills at oilfield areas, such as wellheads, wells, technogenic carbon is introduced, which is sorbed in the soil and causes an increase in its total content [9,10]. In such areas, the total organic carbon content is many times higher than the background values, sometimes tens of times.…”

The article discusses a new approach to the formation of periods of the Periodic Table of Mendeleev. With the help of the new formula and the first proposed quantum states of the outer electron shells of atoms of chemical elements, the periods of the periodic table are reformatted. It is supposed to reduce the number of periods in the table by introducing the corresponding sub-periods. This is confirmed by the material given in the article. The following description of the order of formation of electron layers is proposed: the principal quantum number (n), then the newly proposed quantum states of electrons («first» and «second»), which in turn constitute the electronic configurations of sub-periods in periods, and only then the remaining quantum orbitals (s, p, d and f).

“…According to Yessenamanova's research, the ecological situation here is formed under the influence of natural and anthropogenic factors, the most important of which are the rise in the Caspian Sea level and the rapid development of the oil and gas complex [6]. The increase in oil and gas production, the high aggressiveness of the extracted raw materials affect the processes of intensive pollution of the atmosphere, surface and underground waters, and through them-the soil and vegetation cover, in which, according to the works of Yessenamanova, heavy metals, radionuclides accumulate [7] and petroleum products [8]. In the Atyrau region, solid particles, sulfur dioxide, carbon monoxide, nitrogen oxides and hydrocarbons are released into the atmosphere during the operation of oil fields.…”

This study is aimed at analyzing the content of hydrogen sulfide in the air of the city of Atyrau, located in the northern part of the Caspian Sea of the Republic of Kazakhstan. The analysis was carried out on the basis of monitoring the indicators of the Republican State Enterprise "Kazhydromet" from 8 points located in different directions from the Atyrau oil refinery. Measurements of atmospheric air pollution are made by the GANK-4AR gas analyzer designed for continuous automatic measurement of concentrations of pollutants in the atmospheric air. Hydrogen sulfide was selected as an indicator air pollutant. Atyrau oil refinery is the main object of pollution of the territory of the city of Atyrau, located in the western part of the Republic of Kazakhstan, on the shore of the Caspian Sea. The results obtained show that the content of hydrogen sulfide in the territory of the city of Atyrau in most places shows an excess of the maximum permissible concentration. Especially the excess is observed in the north-western part up to 4-8 maximum permissible concentrations. At two points (in the north-eastern and western parts), the content of hydrogen sulfide did not exceed the maximum permissible concentration.
