Assessment of heavy metals in surface water of River Panjkora Dir Lower, KPK Pakistan
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 3
Abstract
Heavy metals are known environmental toxins causing a number of deadly diseases worldwide. They accumulate in human and other animal tissues through food and water and causing mortality. In developing countries contamination of water with heavy metals is a major problem. It is very need of the day to assess and evaluate suitability of water bodies for drinking and agricultural purposes. Here we show heavy metals Lead (Pb), Copper (Cu), Manganese (Mn), Zinc, Iron (Fe) and Chromium (Cr) concentration in water samples of River Panjkora for six months starting from December to May in order to assess and evaluate its suitability for drinking and agricultural purposes. Atomic Absorption Spectrophotometry showed that Cu, Pb and Cr concentration were not detectable in the River water. Mn and Zinc remained within the permissible limits of WHO with a mean value of 0.0266 mg/l and 0.068 mg/l respectively. However iron was found exceptionally higher concentration in the water with a mean value of 4.733 mg/l during the study period. The high concentration of iron may be possibly due to soil erosion and floods resulting from heavy rains. The study reveal that if iron level could be controlled the water of River Panjkora is suitable for agricultural purposes in terms of the studied heavy metals.
