Assessment of trace and toxic metals in Brahmani river basin

The  present  investigation  is  aimed  at  assessing  the  concentration  of  heavy  metal  ions  along  the stretches of Brahmani  river basin.Nine samples were collected along the stretches of Brahmani basin during the period September-2013 to August-2014. The purpose of this study was to estimate nine heavy metals (Cu, Zn, Cd, Pb, Hg, Fe, As, Ni and Cr) in the surface water of the Brahmani river, one of the most important rivers in Odisha, India. In the selected research area, the Brahmani River is receiving the domestic, industrial, and municipal waste waters/effluents all along its course. All in all, the ascendancy of the analyzed heavy metals in the surface water of Brahmani followed the sequence: Cu>Ni>Pb>Cr>As>Fe>Zn>Hg>Cd. My findings highlighted the deterioration of water quality in the rivers due to industrialization, mining and human activities.
