ABSTRACT This study was conducted in the River Panjkora, Pakistan, in order to assess the level of heavy metals accumulated in the liver, kidneys, gills and muscle tissues of three highly consumed fish species by the local community, Garra gotyla, Cyprinus carpio and Cyprinion watsoni. The heavy metals including manganese (Mn), iron (Fe), chromium (Cr), zinc (Zn), lead (Pb), cadmium (Cd) and nickel (Ni) were determined in the collected fish specimens through an atomic absorption spectrophotometer. Level of heavy metals significantly varied depending upon tissues type and fish species. Cyprinus...
