Estimation of heavy metals in River Kabul at Cantt area Nowshera Khyber Pakhtunkhwa, Pakistan

Abstract

To estimate the amount of heavy metals, a detailed study was design in River Kabul at Cantt area Nowshera. A total of sex heavy metals (Zn, Cu, Cd, Pb, Cr and Mn were analyzed according to the study design. Time to time water sampling were carried out and run by the Atomic Absorption Spectrophotometer machine in the PCSIR laboratories Peshawar. The metals which were recorded in the present study were Zn 1.13-1.85 ppm; Cu 1.02-1.21 ppm; Cd 0.03-1.32 ppm; pb 0.04-1.23 ppm; Cr 0.01-0.16 ppm and Mn 0.00-0.00 ppm respectively. From the present investigation it can be concluded that Zn, Cu, and Cd were exceeded from the recommended permissible limits. So this site of the study area was found contaminated and not recommended for use of living organisms. The peoples residents near to this sight are greatly in risk
