title: Biomonitoring of metals in Ganga water at different ghats of Haridwar: implications of constructed wetland for sewage detoxification.
abstract: An assessment of Ganga river water quality at different ghats of Haridwar, showed high TDS (782.15 mg L(-1)) and BOD (21.76 mg L(-1)) levels at the mixing points of sewage discharge channels and the water was found to be contaminated with appreciable amounts of toxic metals; Cu, Pb, Zn, Cr and Mn (0.178, 0.566, 0.199, 0.177 and 0.160 mg L(-1)). The Ganga water supported exuberant growth of algae and aquatic macrophytes in littoral zone of river, which accumulated appreciable amount of metals in their tissues. Results showed possibility of using metal accumulation potential of plants and algae for monitoring low level of metal contamination vis-a-vis their use in renovating sewage by treating into especially designed constructed wetland.
