Fluoride concentration in bones and differential haemotological characteristics (RBC, haemoglobin, haematocrit, mean corpuscular haemoglobin and mean corpuscular volume) were measured in amphibians, Bufo melanostictus, collected from fluoride-contaminated and uncontaminated areas. The average haemoglobin content, total RBC count and haematocrit (%) in blood samples were found to be significantly reduced, while mean corpuscular concentration and volume were significantly elevated in individuals from the contaminated area in comparison to those from the uncontaminated area. Fluoride concentration was approximately 11 times greater in the bones of toads from the contaminated area.

Key words: Aluminium industry; Bone fluoride; Haematology; Bufo melanostictus.
