Abstract

Nutrients play a major role in food cycle of aquatic ecosystem. Nutrients such as nitrite, phosphate, silicate and sulphate were analysed at Ennore creek for the period of one year in four station at 2021. Nitrite was varied from 0.005 to 0.12 µg/l. Phosphate was varied from 0.02 to 0.68 µg/l. Sulphate was varied from 1.03 to 38.4 µg/l. Silicate concentration was varied from 0.05 to 1.85 µg/l .All the nutrients were supplied by influx of fresh water during monsoon. Beyond, coal based waste water released from the thermal power stations contain all nutrients in a considerable amount which influence greater the nutrient content of study area.
