Diatoms for assessing the ecological condition of inland freshwater bodies
The ecological responses of diatoms to pollution and nutrient enrichment, caused by domestic and municipal sewage, in the five fresh water ponds have been examined. It was observed that diatoms were completely absent in P3 and some species were also absent in P1 and P2. Similarly, diatom diversity was lower in P1 and P2 than in P4 and P5. However, diatom abundance was higher in P4. The Biological ...
