Abstract

The concentrations of dissolved uranium and silicon and the chemical composition of suspended phases in the Narbada, Tapti and Godavari estuaries have been measured as a function of chlorosity. The results suggest the uranium behaves conservatively in all the three estuaries whereas silicon shows conservative behaviour in the Narbada and Tapti estuaries and non-conservative in the Godavari estuary. The variation of chemical composition of particles with chlorosity does not show any systematic trend; the observed scatter can be attributed to variations in mineralogy and size distribution of these particles. The data on chemical composition also indicate that in these estuaries the degree of desorption of elements from particles is much less than those reported for European estuaries.
