摘要：A significant interest to phenols and their derivatives is connected with the fact that these compounds play an important role in human industrial activity and are widely spread in our environment. In the present paper it was investigated the action of one aquatic pollutant - phenol - under two concentration (25 and 50 mg/l water) on some physiological parameters (energy metabolism, respiratory rate, nu mber of erythrocytes and leukocytes, blood glucose level, survival) on perch (Perca fluviatilis) and marsh frog (Pelophylax ridibundus). The choice of these species is ba sed on the fact that they are widely spread and can be well preserved in laboratory conditions. They are also important in the aquatic ecosystems and last, but not least, they are sensitive to various toxic actions. Phenol produces, after two weeks of immersion, a significant decrease of respiratory rhythm, glycaemia values and the number of erythrocytes. Exposure of perch to phenol action produces oxygen consumption decrease after two weeks of intoxication. In the concentration of 50 mg/l, the phenol produces, after two weeks of immersion, a significant increase of the number of leukocytes
