Abstract

A present study has been undertaken to report to the water quality parameters of Pennaiyar estuary compared the concentration of water quality parameters like temperature was ranging from 26.0 to 32.4°C, salinity values ranging from 23 to 34ppt, pH was ranging from 7.2 to 8.3, dissolved oxygen content was ranging from 3.36 to 5.36 mg/l, ammonia was ranging from 0.136 to 0.683μmol/l, nitrate was ranged from 7.39 to 8.29μmol/l, nitrite was ranging from 1.83 to 2.15μmol/l, total phosphorus was ranging from 0.046 to 1.553μmol/l, and silicate was ranging from 1.193 to 2.293μmol/.were studied from Pennaiyar estuary, Cuddalore, southeast coast of India from July 2013 to June 2014.Above the water level due to the ceaseless release of domestic manure and trade waste matter in the estuary. The duration of the estuary concentrations of nutrients and other water quality parameters potency have been controlled by the anthropogenic inputs from point and non-point sources.

Keywords: Physico-chemical parameters, nutrients, monthly variation, Pennaiyar estuary.
