Mesta River
Biological Quality Elements and Ecological Status

Wetlanet. The present book is aimed at summarizing the most of the studies have been carried out during the last three decades on the ecosystems of the Mesta – a transboundary river shared between Bulgaria (upper stretch) and Greece (lower stretch and Delta). This river was a subject of careful hydrobiological and ecological studies during the last decades, mostly because it was an excellent example to investigate processes of the heavy loads of the pollution with organic matter generated by cardboard and yeast industries in the Razlog Valley.
