The fish were collected from Indus River, Head Taunsa, Dera Gazi Khan, Punjab, Pakistan. The organs of collected fish were separated and frozen at -20 ºC. The organ samples were digested by using perchloric acid and nitric acid. The concentration of accumulated metals in organs was measured by using an atomic absorption spectrophotometer.
