IMPACT OF PETROCHEMICAL EFFLUENT ON HEMATOLOGICAL PARAMETERS IN THE FRESHWATER FISH, LABEO ROHITAAbstract
The present investigation was carried out the effect of petrochemical effluent on hematological parameters in freshwater fish, Labeo rohita using the standard method. The petrochemical effluent has the potential to cause developmental effects in fish. Blood offers important profile to study the toxicological impact on animal tissues. Hematology is used as an index of fish health status under different stress conditions on exposure to pollutants. The fish Labeo rohita was exposed to sub-lethal concentrations (30 ml/L) of petrochemical effluent for different h (24, 48, 72 and 96) and parameters like RBC, WBC, HB, MCV, MCH MCHC, PCV has been analyzed. All hematological parameters except WBC were found to be decreased from control, and the WBC was increased in all exposure periods indicating that test fish, Labeo rohita suffered hemolytic anemia and leucocytosis. Increase in time produced a declining value of RBC, Hb, MCV, and MCH also exhibit the sub-lethal concentrations of the petrochemical effluent.
