title: THE INFLUENCE OF BITUMINIZATION IN KARST CONDITIONS ON THE NATURAL-TECHNOGENIC TRANSFORMATION OF A SMALL RIVER BASED ON GEOCHEMICAL DATA AND BIOTESTING
abstract: A set of studies consisting of laboratory experiments and field surveys based on geochemical methodsand biotesting allows us to formulate and solve problems related to identifying the consequences of bituminization, natural-technogenic transformation of a small river in karst conditions. A small river acts as a receiver of natural-technogenichydrocarbon flow in the karst region. The chemical composition of the river waters is typical for the conditions of oilfieldtechnogenesis: samples are enric
