The information content and effectiveness of ecological research of the territory can be improved using the methods of multivariate analysis and mapping of the results. The article presents the analysis and mapping results of spatial and temporal trends of hydrocarbon pollution in the Tromjegan river basin for the period 2006–2018 using the tools of ArcGIS Pro. The informational and basic research is the data of local environmental monitoring of licensed blocks of the Khanty-Mansiysk Autonomous Okrug — Ugra. Pollution analysis was carried out on the basis of a detailed study of the geography of the source data using statistical calculations (minimum, average, maximum distances between sampling points, Getis-Ord Gi* index). Thematic maps were constructed using data averaged over the year. The spatial and temporal dynamics of hydrocarbons concentration in surface waters for 2006–2018 is analyzed using the “Hot Spot Analysis” tool. A temporary cluster section of hydrocarbons average annual concentration according to the Getis-Ord Gi* indicator allowed us to identify trends in the dynamics of indicators. Maps of hydrocarbons average annual concentration were compiled and the results of a spatial-temporal analysis of hydrocarbons average annual concentration in surface waters were presented. The identification of patterns in large arrays of long-term data and the consideration of the spatial component are necessary elements of modern environmental research. Analysis of the time series of average annual concentrations in the Tromjegan river basin showed a clear trend in the dynamics of hydrocarbon pollution. The findings can be the basis for making managerial decisions in the environmental monitoring of licensed blocks of the Khanty-Mansiysk Autonomous Okrug — Ugra.

The article presents the results of environmental monitoring of water and ice samples from the Ural River in the area of ​​the unorganized beach of the village of Ilek in cold and warm seasons, and analyzes the results. Priority pollutants were identified, and a ranking by pH and salinity of the water body was carried out. An integral assessment of the ecological state of the water body and a study of the water suitability index in this body were carried out. Various measures are proposed to preserve and ensure the required quality of surface waters of the Ural River in the study area.

First Time

Hydro/chemical explorations on the assessment of water pollution have been conducted on the Velikiy Novgorod water bodies (the Volkhov River with its tributaries, the Veryazha River, and the urban water bodies). Surface waters contamination levels have been determined, for the first time the map of spatial differentiation of the Velikiy Novgorod water bodies’ pollution has been made, and the general status of the urban water bodies has been assessed. The link between territorial differences in the water bodies’ pollution level and the city’s functional zones distribution has been highlighted.
