EFFECT OF PHENOL INTOXICATION ON SOME PHYSIOLOGICAL PARAMETERS OF PERCA FLUVIATILIS AND PELOPHYLAX RIDIBUNDUS

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, number of erythrocytes and leukocytes, blood glucose level, survival)

on perch (Perca fluviatilis) and marsh frog (Pelophylax ridibundus). The choice of these species is based 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.

on perch (Perca fluviatilis) and marsh frog (Pelophylax ridibundus). The choice of these species is based on the fact
