Abstract
The present study was carried out to determine the physico-chemical characteristics and nutrients in two stations in Kottakudi Estuary, Thirupulani, Ramanathapuram, Southeast coast of India during January to December 2009. Various parameters have been studied: surface water temperature, salinity, pH, dissolved oxygen, nitrate, nitrite, ammonia, phosphate, silicate. Concerning the salinity, the maximum value has been recorded in the station 2 when compared to station 1 and this is due to salt pane discharge and evaporation also. The minimum and maximum values of pH and dissolved oxygen (mg L[sup]-1[/sup]) were: 7.4-8.2 and 4.8-5.4, respectively. The nitrate, nitrite, phosphate, silicate and ammonia were found to be higher in the station 2 than in station 1. It has been observed from the present study that the higher values are observed in station 2 than station 1 may be due to the industrial effluents mixing up with estuary.
