Heavy metals concentration in the sediment load of river kalpani at district nowshera, khyber pakhtunkhwa Pakistan
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 4
Abstract
The present study was conducted to assess the heavy metals concentration at Kalpani river at district Nowshera Khyber Pakhtunkhwa Pakistan. The heavy metals studied were lead (Pb), chromium (Cr), cadmium (Cd), Zinc (Zn) and Nickel (Ni). Sampling was carried out during the months of July to October, 2013. The heavy metals concentration was determined by using Perkin Elmer AS 3100 flame atomic absorption spectrophotometer. The concentration of the studied heavy metals was varying among sampling months and sites. Overall mean values recorded (wet weight) for Cr, Zn and Ni were 0.214±0.016 μg g-1, 0.552±0.099 μg g-1 and 0.509±0.069 μg g-1 respectively while Pb and Cd was not detected in any sediment sample across all the sampling sites. The results showed, heavy metals were present in the order of Zn>Ni>Cr while Pb and Cd was not detectable at all. Results showed that all the studied heavy metals were falling in suggested permissible limits except Zinc, which was falling out of permissible limits for all sampling months and sampling sites.
