摘要：Chromium is one of the heavy metals present in the Tannery effluent. Chromium is kno wn to cause various health effects. The health hazards associated with exposure to chromium are dependent on its oxidation state. The hexavalent form is toxic than trivalent form. The hematological alterations produced on exposure to sub - lethal concentrati on (1/10 th of LC 50 /96 hrs) of chromium were investigated in fresh water fish, Labeo rohita for 7days and 30 days respectively. Results revealed statically significant decrease in RBC, Hb, PCV, MCH, and MCHC in all the experimental animals when compared to the control with an increase in exposure days. In contrast to this, the WBC and MCV values were significantly increased. The decrease in hematological parameters clearly indicates that the exposed fishes have become anemic due to heavy metal exposure.
