Effects of nitrogen fertilizer on Capoeta capoeta: an immunohistopathological and biochemical investigation

Increased use of fertilizers to increase plant production causes important environmental pollution not only in soil but also water resources. Soil structure, quality, systems, and biodiversity are adversely affected by the unconscious fertilizers. In this study, Capoeta capoeta (Guldenstaedt 1773) were used investigate degenerative effects nitrogen fertilizer. Twentyfour fish equally allocated into three groups; group 1 (control), 2 (15 mg/L fertilizer water) 3 water). Fish exposed for 15 days then tissues gill, liver intestine investigated immunohistopathological biochemical means assess tissue water. Varying degrees changes observed all organs. histopathological examinations, hydropic degeneration was hepatocytes Blunting association gill occasional blunting intestinal detected. Catalase SOD immunoreactivities increased tissues. There an immunoreactivity fish. Total antioxidant status (TAS) both experimental groups (p < 0.05), total oxidant (TOS) did change. The results experiment showed that resources may impair health affecting cellular level.
