Investigation of physical and chemical heterogeneity of lake sediment sapropols in the okreg-yugra territory of khanty-mansi autonomous region (Russia)

The results of statistical processing of the physicochemical parameters of sapropel of lake deposits of the territory of the Khanty-Mansi Autonomous Okrug-Yugra are presented, which indicate that the heterogeneity of the composition and properties of sapropel is primarily determined by the available geographical position of the studied lakes: Their confinement to the right or left banks of the Ob River valley depend on the composition of the parent substrate the lake basins are formed on. The geomorphological factor imposes a minimal effect on the variability of the physicochemical characteristics of sapropel, being reflected only in the 4th most important of the identified factors. In contrast, none of the factors affects the deterioration of the balneological properties of sapropel
