Saikia MK*, Baruah R and Kataki M

Diversity study of Algal community particularly Cyanobacteria in terms of influential effluents released by pulp and paper, oil and fertilizer factory of Assam was conducted with a view to find out its impact on distributional pattern of Cyanobacteria according to increasing and decreasing trend of pollution load from the source. Palmer applied for rating the genus and species of Cyanobacteria. The results revealed that palmer’s pollution tolerant index for algal genera and species was highest in paper mill area followed by oil and fertilizer. Similarly the number of pollution tolerant genera and species of Cyanobacteria was recorded highest in S1 and lowest in S3 which signify the higher pollution load in nearby area and lowest in the areas situated at long distance from the sources.
