Abstract
The Danube is a large eutrophic river and may be one of the best studied rivers in the world. This paper presents a short characterization of the biological water quality based on data from the 1986–1992 period, collected in the Southern Hungarian section at 1480.2 river km. Variations in the hydrological features (including discharge and turbulence) are the most important factors determining the total phytoplankton biomass in the River Danube. A good correlation has been found between chlorophyll a content and discharge, from early spring to autumn, whereas the suspended matter appeared weakly related to discharge. In addition, some taxonomic notes refer to the most common members of the phytoplankton, as well as to several rare taxa.
