title: Ecological study on the status of pollution by steel plant waste on river Damodar at Barnpur, West Bengal.
abstract: This paper present a study of physico-chemical quality of river water and abundance and distribution of phytoplankton community in a stretch of river Damodar from November 1996 to October 1998 in relation to steel plant effluents. Phytoplankton and water quality of S1 (Control zone), S2 (Out fall zone) and S3 and S4 (Downstrean zone) were studied and compared. Low transparency and pH, and high TSS, temperature and total hardness were the characteristic of S2 and S3, indicating a stressful habitat. Effluent discharge significantly changed the phytoplankton community structure. It was also noticed that S2 and S3 were characterized by low number of taxa with their higher abundance. The discharge of steel plant effluent obviously caused habitat degradation resulting ecological modification of phytoplankton community of river Damodar at Barnpur.
