  Abstract = {The present study consists of the analyses of dissolved inorganic nutrients (NH4 +, NO3 -, NO2 -, PO4 3-, Si(OH)4), dissolved organic nitrogen (DON), particulate nitrogen, particulate organic carbon, amino acids and δ15N of particulate nitrogen and NO3 - from Hooghly and Matla estuary. Hooghly estuary was sampled at 2 stations, at Kolkata and ca. 60 km downstream. Mangrove dominated Matla estuary was investigated along a N-S transect. Dissolved inorganic nitrogen, PO4 3- and DON concentrations were low, especially for the Hooghly site at Kolkata. Human influence, however, was revealed by the more labile nature and elevated concentrations of amino acids in Kolkata. Release of nutrients from particulate matter during estuarine transport resulted in higher NO3 - and PO4 3- concentrations downstream Kolkata. In Matla estuary no human influence was detected and nitrogen fixation was observed.},
