Analysis of heavy metals in river Kabul at Sardaryab Khyber Pakhtunkhwa, Pakistan

Abstract

The present study was conducted to analyse of heavy metals such as Zn, Cu, Cd, Pb, Cr and Mnin River Kabul at Sardaryab Khyber Pakhtunkhwa, Pakistan. Mainly sampling of water was carried out from three locations of the River Kabul at Shah Alam tributary. All the collected samples of water were subjected to the heavy metal detection digital computerize machine (Atomic Absorption Spectrophotometer).The heavy metals analyzed in the present research were in the range of Zn 1.14-1.86 ppm; Cu 1.03-1.22 ppm; Cd 0.12-0.89 ppm; Pb 0.08-1.08 ppm; Cr 0.02-0.12 ppm and Mn 0.03-0.29 ppm respectively. Heavy metals which were above the permissible limits were Pb, Cd and Cu while the remaining heavy metals remain below the permissible limits.
