State the organic pollution level in rain fed ponds, Noakhali, Bangladesh


Author(s): Najmus Sakib Khan and Saiful Islam

Abstract: The present study has been conducted to assay the water quality of rain fed ponds by determining the organic pollution level according Palmer’s algal pollution index. A total three genera (Ankistrodesmus, Chlorella, Scenedesmus) of Chlorophyceae, four genera (Cyclostella, Navicula, Synedra, Melosira) of Bacillariophyceae, two genera (Euglena, Phacus) of Euglenophyceae and only one genera (Oscillatoria) of Cyanophyceae were identified for determination of Palmer’s algal pollution index. Chlorella and Euglena were most dominant phytoplankton in all observed rain fed ponds during sampling. Algal pollution index of pond A, B, C, D, E and F was 16, 23, 21, 13, 10 and 17 respectively. According to the index value pond A and F were found probable high organic pollution. On the other hand pond B and C were observed confirmed high organic pollution. More over pond D had moderate pollution and pond E was detected as lack of organic pollution. Some physico-chemical water quality parameters (water temperature, transparency, total suspended solids, PH, total alkalinity, free CO2 and ammonia) were also estimates as a supporting water quality analysis during sampling periods.
