ASSESSMENT OF PHYSICOCHEMICAL PARAMETERS IN THE RIVER TORSA, WEST BENGAL, INDIA: TO INVESTIGATE THE SUITABILITY FOR LIVING ORGANISMSTAPAN SARKAR1, SUKANTA DEBNATH, BRATINDRA KRISHNA DAS AND MITHUN DAS
River Torsa is a trans boundary river of China, India and Bangladesh. It is a tributary of the river Brahmaputra. A study was done on the physicochemical parameters of this river to assess the suitability to biological life. Three sampling sites were selected for the study. Water temperature, pH, Water depth, TDS, electrical conductivity was assessed at the spot. Dissolved oxygen, total alkalinity, total hardness, free carbon dioxide and chloride were determined by standards methods of APHA (2005). Results indicates that all the physicochemical parameters of this river are within the optimum range and suitable for living aquatic organisms. The river Torsa is free from any major anthropogenic activities.
