FIELD: water toxicology. SUBSTANCE: daphnias, proposed as test object, are placed in test and reference solutions. Degree of toxicity is assessed from physiological condition of daphnias, which is manifested by the tendency of daphnias to rise toward aqueous solution-air interface. EFFECT: increased sensitivity and accelerated assessment. 1 tbl
