The present review emphasizes the importance of the bioassessment of freshwater quality especially running waters based on diatom metrics. Nutrient enrichment and hydromorphological alternation driven by human activities are the main factors for the ecological compromise of freshwater ecosystems.

  • Phytoplankton community and their correlation with environmental factors were investigated in the Dong Nai River. Higher diversity was observed in dry season with the dominance of diatom. Environmental variables were different between upper and lower sections. Phytoplankton metrics and the nutrient concentration characterized a pollution gradient along the river. Nutrient levels and turbidity governed the distribution of phytoplankton structure in the river.
