Sterols, n-alkanols, organic carbon (OC), C/N ratios and carbon isotope data (delta 13C) were investigated in sediments of the urban Capibaribe River estuary, NE Brazil, in order to assess allochthonous and autochthonous sources of organic matter (OM). Sedimentary OC values are high, but C/N ratios and delta 13C data generally fall within the range of values reported in other riverine systems, and suggest mixed inputs from aquatic and terrestrial matter. Mean values for total 4-desmethyl… CONTINUE READING
