Current study was carried out to determine heavy metals in six species of fishi.e.Oreochromis mosambicus, Cyprinus carpio, Tor putitora, Cirrhinus mrigala, Labeo rohita and Ctenopharyngodon idella, belonging to class Cyprinidae, collected fromthe fish markets of Quetta city, Balochistan. Concentrations of Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu), Cadmium (Cd) Lead (Pb), Chromium (Cr) and Nickle (Ni) were determined in Liver, Heart, Gills and Muscles of selected species by using atomic absorption spectrophotometer. Concentration of Fe was higher than the World Health Organization (WHO) limits in all species exceptCtenopharyngodon idella. Concentration of Zn was within the limits exceptCyprinus carpio. Concentration of Mn, Cu, Cd and Pb were below the limits set by WHO. Cr and Ni were not detected in any species. The concentrations of heavy metals in edible part (muscles) of all species were below the WHO limits. So, current study reveals that the fish of selected species are safe for human consumption.
