Abstract: Organic carbon, nitrogen, C/N ratio and nature of sediments at 4 stations, viz. upstream of industrial complex (st 1), effluent discharge area (st 2), barmouth (st 4) and point about midway between sts 2 and 4 (st3), on the northern limb of Cochin backwaters, Kerala, India are reported. Effluents discharged into the river Periyar at Udyogamandal (Eloor), prior to its joining the backwaters cause high local fluctuations in the parameters studied. Seasonal variations are most pronounced at st 2 and least at st 3. Fine grained sediments and organic matter show a direct relationship only at st 4. Organic carbon and nitrogen though positively correlated at all stations is significant only at st 1. Nature and extent of fluctuations in the composition and nature of sediments at st 2 indicate a high stress environment.
