Description
In all the cases tissues from Gills, Bones, Liver, Blood, Kidneys, Muscles, Skin and GI tract were removed and analyzed by AAS to find lead accumulation. The Bio-Concentration Factor (BCF) was calculated .The BCF varies from organ to organ. Additionally , X-rays photography was made on the chronic treated fishes from time to time, to see whether skeletal tissue is a target of the heavy metal or not. The Co-relation Co-efficient ( r’) in these tissues between Lead treatment and Lead accumulation was found to be highly significant suggesting it both as a dose-dependent and time-dependent process.
