We examine the chemical composition of industrial effluents discharged by the enterprises of the Usolie industrial zone directly into the Angara river. An assessment is made of the degree of their transformation, the length of flows and of the distribution of technogenic macro- and biogenic elements. Using the concentrated source of pollution as an example, we demonstrate the role played by self-purification processes in the formation of contemporary water composition in the Angara river.
