Effect of sublethal concentrations of phenol on some enzyme activities and blood sugar level of carp (Cyprinus carpio L.).
To measure the phenol induced tissue necrosis and its adverse effects on nervous system, GOT, GPT, LDH, AChE enzyme activities and blood sugar level detections were used under aquarium conditions and in field experiments.Under aquarium conditions all experimental animals survived 5 ppm phenol concentration even at 96 hr exposure time. However the increase of plasma GOT, GPT, and LDH activities reflected serious tissue damage.In field experiments the plasma GOT. GPT, and LDH activities three times elevated parallel with the increasing phenol contamination of the water.The measurement of our biochemical parameters appeared to be a sensitive biomonitoring indicators to assess exposure of fish to antropogenic agents in the natural environment.
