Abstract:

Accumulation of nickel, lead, copper and zinc in the liver of a freshwater fish, Tor putitora has been studied from polluted waters of River Kabul at two different sites and compared with those from pristine Warsak Dam reservoir upstream of polluted part of the River Kabul. The liver of fish from polluted site showed higher concentration of zinc (1300% and 3100%), nickel (21.1% and 25.5%), lead (26.99% and 56.8%), copper (158.8% and 34.1%), and chromium (36.3% and 14.2%) from samples at site 1 and 2, respectively, when compared with the control fish. The order of concentration of metal in liver was Zn > Cu > Pb > Ni > Cr.
