摘要：Both water and sediment are the valuable natural resources for aquatic organisms whose quality change in a minor range can be very harmful. Growing population, urbanization, increasing living standard and other activities have brought severe changes in the quality of both water and sediment. River Ahiran is a small tributary of the River Hasdeo. River Hasdeo is the largest fresh water resources of Korba city, Chhattisgarh, India. The present study was taken on River Ahiran; it is an important water source of Katghora block and its surrounding villages. River Ahiran was greatly influenced by effluents of small scale industries and domestic wastes. The study revealed that the total solids, total dissolved solids, total suspended solids, ammonia, nitrite, phosphate and chemical oxygen demand of water of this area was found higher. Biological oxygen demand was found under the limit and dissolved Oxygen was found lower than the standard limit. The sediment of the sampling points of River Ahiran contains higher concentration of lead and cadmium than the permissible limit recommended by Indian Standards and World Health Organization. The study highlights the pollution load on River Ahiran due to mixing of industrial and domestic wastes.
