ABSTRACT

The effects of T-2 toxin, a metabolite of fungi of the genus Fusarium, on Daphnia magna were studied. Mycelial mold fungi affect grain products and the toxin under study causes pathological changes in the organism of mammals. LC₅₀ of T-2 toxin for water fleas equals 0.07 mg/L. 100% mortality in these crustaceans was registered at 0.5 mg/L. There were analyzed changes of levels of excited chemiluminescence intensity of the water ambient for D. magna at various concentrations of T-2 toxin and varied duration of experiments. Chemiluminescence indication is proposed to be used for express testing.
