Pollution profile of a river
- 58 Downloads
A host of chemical industries subject the river to pollutants such as acids, alkalies and their salts, trace metals and radionuclides belonging to the Th and U chains. Proximity of different outfalls and poor lateral mixing in the river are responsible for high local aquatic concentrations. Scavenging reactions, in situ, and sedimentation of suspended matter result in the accumulation of radionuclides near the outfall area. Monsoon ‘flushes out’ the river into the backwater area and translocation of sediments is the major factor in the transport of pollutants.
