Abstract


The concentrations of nine heavy metals (Fe, Zn, Ni, Cu, Cd, Cr, Pb, Mn and Co) were determined in riverbed sediments collected from selected ten locations on River Parbati in Baran district of Rajasthan in pre-monsoon season in consecutive three years (2008 to 2010) to evaluate their levels and distribution along river length. The ranges of the measured concentrations in the riverbed sediments on dry basis are as follows: Fe: 0.35-0.88%; Zn: 49.0-106.7mg/kg; Ni: 4.2-18.3mg/kg; Cu: 19.8-68.2mg/kg; Cd: 0.20- 0.75mg/kg; Cr: 5.7-14.9mg/kg; Pb: 1.1-7.3mg/kg; Mn: 37.5-138.9mg/kg and Co: 0.90-3.8mg/kg on dry weight basis. To assess metal contamination in sediment, US Environmental Protection Agencys (USEPA) guidelines were applied. To evaluate the origin Pearson Correlation Coefficient was calculated, which shows that there are no significant correlations among these metals, indicating that they have different anthropogenic and natural sources.
