The results of studying the features of the spatial distribution of macro- and microelements in the “water – bottom sediments” system in the channel of the Uzynbulak creek (“Degelen” site of the Semipalatinsk test site, Kazakhstan) are presented. The studies were carried out in the summer of 2015. As a result of the study of the chemical composition in surface waters and bottom sediments of the Uzynbulak creek, the content of Li, Be, Na, Mg, K, Ca, V, Ni, Mo, Fe, Sr, Al, Zn, Ba, La, Ce, U was revealed. The nature of the origin and the main factors determining the increased content of a number of the studied elements have been determined. The main mechanisms of the formation of the elemental composition in surface waters, the degree of spreading of elements exceeding the MPC (maximum permissible concentration) beyond the “Degelen” site are considered.

Using a complex of remote and surface geophysical methods in the eastern part of the East European Platform, regional meridional heterogeneitieswere revealed; it isshown that these heterogeneitiescan becaused by low-density and magnetically active rocks in thecrystalline crust and mantle. The totality of geological and geophysical data indicates the relationship of meridional heterogeneities with transcontinental deep faults.

The article considers the temperature and humidity regime of the Left Bank of the Saratov region in various natural climatic periods of the state of the earth’s climate system – the first wave of global warming, stabilization, the second wave of global warming. It is noted that against the background of rising temperatures from one climatic period to another in the Trans-Volga region, the amount of precipitation in the cold half of the year increases. The trend in precipitation during the warm period is ambiguous. Against the background of the second wave of global warming, at two of the studied stations, an increase in the amount of precipitation during the warm half of the year is observed, and at the other two ones a decrease occurs. Calculation of hydrothermal coefficients revealed a trend of increasing the degree of aridity in the Left Bank of the Saratov region. The authors conclude that there is an increase in hydrometeorological risks of crop cultivation in this area.

In the article, in a comparative analysis, for the periods from 1991 to 1998, 2015 and 2022, the issues of the territorial prevalence of basal cell skin cancer in Saratov are considered. The residential areas of patients were studied and mapped taking into account risk factors. The result of the study was an oncoecological analysis of urban landscape sites and the creation of a scheme for the active search for early forms of skin cancer.

The work is carried out approbation of the algorithm for the complex interpretation of geophysical data using data classification algorithm. Distributions by class are obtained and compared with petrophysical materials from published sources. This data is compared and geological composition of the studied area is obtained. The applicability of this approach for the integrated interpretation of geophysical data is shown, including low-level studied areas with a complex geological structure.

The temperature and humidity regime of the Right Bank is considered according to the data of four weather stations in three natural climatic periods – stabilization, the first and second waves of global warming. There is an increase in the rate of warming from one natural climatic period to another. Against the background of a progressive rise in temperatures, there is an increase in the amount of precipitation in the cold half of the year and its decrease in the warm one. The revealed trend may indicate an increase in weather and climate risks of crop production in the Right Bank of the Saratov region

The structure of the actinopterygian fish genus and species Toyemia tverdochlebovi Minich has been completed for the first time using a previously unknown complete skeleton and skeletal fragments from Late Permian localities of Eastern Europe. The structure of a head which so far remained unknown in the genus is described. The dorsal fin location far from the head near the caudal region was confirmed as expressed earlier by the taxon’s author.
