INDUCED ASH TOXICITY EFFECTS ON THE HEMATOLOGICAL AND BIOCHEMICAL CHANGES OF CYPRINUS CARPIO L. 1785.

This study was the first of its kind in Iraq, which aims to assess the risk of Durah power plant ash concentrations in hematological and biochemical changes of common carp. The result shows that the mean RBC value was from 1.3±0.015 to 0.93±1.54 was recorded in a group of 0.5 and 3ppt after two-six weeks of exposure, respectively. In contrast, the mean Hb value were from 10+0.26 to 6+0.11g/dl was recorded in blood sample exposed to 0.5and3ppt after two-six weeks of exposure, respectively. Regarding to PCV was decreased from 30%±0.54 to 18%±0.74 at the end of 45th days of exposure in treated group as compared to control group. Moving to WBCs increased from 10.87±0.31mm³ in 0.5ppt to 20.4±0.14mm³ at the 3ppt concentration after six weeks of exposure period. Turning now to activity of liver enzymes the results of SGPT value were from72±1.665 to126±0.48U/L was recorded in blood sample exposed to 0.5 and 3ppt after two-six weeks, respectively. All these data were higher than control group. However the mean SGOT values were from 274±13.52 to397±18.42 U/L was recorded in blood fish exposed to 0.5 and 3ppt after two-six weeks, respectively.Our study concluded that presence of toxic ash in aquatic environment may produce systemic toxic effects and reveal the changes in blood cells count of fish also pose hazardous alternations in biochemical parameters.
