Intoxication of the natural aqueous medium resulting from disbalance of redox and free-radical intrabasin processes

Abstract

The mechanisms of redox processes occurring in natural water with participation of molecular oxygen and the product of its reduction hydrogen peroxide as a carrier of reactive oxidative equivalents and hydrosulfide as a carrier of reducing equivalents in the formation of a toxic quasi-reducing state of the natural water medium were analyzed. The conditions for the formation of the toxic superoxidation state of the aqueous medium as a result of intensification of free-radical processes involving OH radicals and microcolloidal mixed-valence manganese(III, IV) particles were characterized.
