This study was undertaken to evaluate the effects ofÂ Ferronickel smelter in concentration Â of lead, cadmium, zinc, copper and nickel in tissue of femur, tibia, liver kidney and testes, levels of plasma alanin aminotransferase (ALT), aspartat aminotransferase (AST), alkaline phosphatase (AP) blood Î´-aminolevulinic acid dehydratase (ALA-D), serum total proteins, hematocrit and hemoglobin in FeralÂ pigeons.Â Pb was detectable only in tissues of femur and tibia; Cd and Cu in liver and kidney, Zn in all tissues while Ni only in tissues of pigeons of courtyard smelter. Zn concentration was significantly higher (P<0.05) in kidney of courtyard smelter in comparison with reference. Plasma AP was significantly higher (P<0.001) in pigeons of reference in comparison with pigeons of courtyard smelter, while ALT and AST were relatively unchanged. The ALA-D activity of pigeons from courtyard of smelter was significantly inhibited (P<0.001) and an inverse correlation between Pb concentration in femur and tibia and ALA-D activity (r = -877; P<0.001; r = -0.787; P<0.01) was established. The total serum proteins of pigeons of courtyard of smelter was significantly lower (P<0.001). Hematocrit and haemoglobin were unchanged. Suggestion: Feral pigeons as worth biomonitoring organisms for evaluation of environmental pollution based on Ferronickel industry.
