Chlorophyll 'a' Particulate Organic Carbon and suspended load were estimated for one year from two distinct mangrove areas of Cochin backwaters, viz. Puthuvypeen and Nettoor. Environmental parameters like tau degrees C, S ppt and pH were also measured. Chlorophyll 'a'. Particulate Organic Carbon and suspended load were high at Puthuvypeen. The annual average for 6 stations ranged between 6.35 and 30.67 mg/m sup(3), 4.05 and 21.27 mg/l and 48.78 and 146.24 mg/l respectively. Seasonal variation was well marked during monsoon. Mangrove region at Nettoor showed comparatively low values for all the above parameters. The annual average for chlorophyll 'a'. Particulate Organic Carbon and suspended load for 4 stations varied from 2.41 to 3.18 mg/m sup(3), 1.96 to 2.39 mg/l and 31.89 to 37.79 mg/l respectively. High pigment values coincided with high POC values in both regions. The values of present study are well comparable with values reported from the mangrove areas of south east coast. The POC, chlorophyll 'a' and suspended load of the mangrove areas of the study are high compared to other areas of Cochin backwaters
