Abstract

Selected heavy metals Nickel, Chrome, Copper, Manganese, Zinc, Cadmium, Lead, Iron, Aluminium, and Arsenic concentrations were determined in gills, liver and muscle of Carassius auratus, Rutilus rutilus and Blicca björkna collected from shallow - turbid lake, Manyas Lake (Turkey). Metal concentrations in most cases were high in gill and low in muscle or in liver. However, from time to time, lower amount of Copper and Zinc concentration were measured in muscle and higher value was recorded in liver of the fishes. Our results suggest that according to international criteria and Turkish regulations, heavy metal concentrations were markedly above the permissible levels for fish.
Key words; Heavy metal concentration, Manyas lake, Carassius auratus, Rutilus rutilus, Blicca björkna
