Abstract

The distributions of water quality parameters viz. temp, salinity, dissolved oxygen (DO), biochemical oxygen demand (BOD), total suspended substances (TSS), nutrients NO 2-N, NO 3-N, NH 4-N, PO 4-P, SiO 4-Si, total nitrogen (TN), total phosphorous (TP) and Chlorophyll-a (Chl-a) were studied in the Mahanadi river and costal environment of Paradip in two different seasons i.e. post-monsoon and summer during 2006-2007. Results of nutrient concentrations were exhibited higher indicates that large inputs possibly from two major fertilizer plants, municipal sewage from Paradip town and agricultural runoff. In the estuary most of the nutrients showed higher values (NO 3 7.23 μmol/l, NH 4 6.32 μmol/l, PO 4 16.03 μmol/l and SiO 4 15.32 μmol/l) during post-monsoon as compared to the costal stations. The PO 4 TN, TP and SiO 4-Si showed a well-defined pattern of distribution with higher concentration in estuarine water of Mahanadi estuary during summer.
