The character and intensity of activated chemiluminescence of Daphnia living medium are investigated depending on the effect on them of various concentration different in nature toxic substances, such, as potassium bichromate, methomyl and tween-80. It is shown, that the toxic influence of these agents can be defined by registration of stimulating effect of Daphnia's exometabolites on the process of chemiluminescence. The sensitivity of the method makes: for potassium chromate--0.005 mg/l, methomyl--0.0013 mg/l and tween-80--0.1 mg/l.
