Water from the Kremenchug reservoir [USSR] during blooming of blue-green algae, predominantly Microcystis aeruginosa, Aphanizomenon flos-aquae and Anabena flos-aquae, was administered daily to rats for 2.5 mo. Results indicated lowered cholinesterase and blood catalase activity, lower overall thiamine in the organs, the presence of thiaminase, higher concentrations of insufficiently oxidized products in the blood (particularly pyruvic acid) and degenerative changes in the liver and myocardium. Disturbances of carbohydrate oxidation is one of the basic elements of the mechanism of toxic action on warm-blood animals. The possibility of exposure of humans and animals to biologically active metabolites of blue-green algae indicates that the blooming in water is a potential factor in the decrease of water quality and may lead to adverse consequences.
