“…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.

“…Monitoring and forecasting the state of the environment in the sphere of influence of the oil and gas complex is a prerequisite for taking timely measures to protect the natural environment from degradation. The content of heavy metals in the soil is a complex and informative indicator of the degree of soil pollution and can be used in environmental monitoring of technologically disturbed territories [4][5][6].…”

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).

Effective management of wastewater sludge is currently one of the most pressing environmental problems in Nur-Sultan city, which becomes more acute year by year and requires immediate solution. Wastewater sludge is almost completely stored at the treatment facilities, which turns them into a source area of bacteriological and toxicological hazard. For this reason, the most urgent problem now is the development of new sustainable and zero waste technologies that can effectively expedite the reduction of silt sludge and lead to a significant decrease in their final volume. This article analyzes various methods of sludge disposal. It is shown that of all possible technology options with admissible environmental impact and the best economic indicators, the most acceptable is the method of thermo-catalytic oxidation of wastewater sludge in a semi fluidized bed of the catalyst, the use of which can fundamentally change the situation with the sludge disposal. Also, the article studied the composition and carried out measurements of silt sludge contamination with heavy metals and oil products at wastewater treatment plants of Nur-Sultan city. It is pointed out that the LOC for the TPH-in-soil is 1.5 g/kg, from which it can be concluded that there is a significant excess in the wastewater sludge for this indicator, and studies for the heavy metals presence in the wastewater sludge showed that sediments can have a toxic effect and are classified as 4 class of hazard.
