Abstract
The study aims to assess the trophic state of Danube River and the main tributaries in
the Southern part of Romania through chlorophyll „a” (Chl a) dynamics during 2015.
The samples were collected with a seasonally frequency. Several environmental
variables such as water temperature, pH, salinity, dissolved oxygen, nutrients were
considered. In addition, the qualitative analysis of phytoplankton community was
performed.
The integrative approach, which included both in-situ and laboratory analysis,
highlighted positive correlation between abiotic and biotic parameters.
The chlorophyll „a” dynamics showed a close dependence with the sampling sites
characteristics, the point sources of pollution, phytoplankton community and specific
changes of chemical parameters.
