Ecology and biodiversity of any river depends on the biologically significant ions like sodium, potassium, calcium, magnesium, chloride, nitrate, phosphate, carbonate, bicarbonate etc. present in river water. In this study four cations and five anions were measured and monitored every month (for the period June 2020 to May 2021) for these three most important rivers of Nadia district, West Bengal, India. These rivers are Jalangi, Churni and Bhagirathi [1-2]. These nine inorganic ions play important and vital role on the growth of aquatic flora and fauna present in the river. This study clearly helps to understand the background scenario of the rivers ecosystems and one can easily compare the ecological variation present within Jalangi, Churni and Bhagirathi with respect to biologically significant ions.
