In the Bulgarian part of the Black Sea coast there are seventeen rivers and three lakes which contribute to the pollution and eutrophication of the Black Sea. The hydrophysical and hydrological characteristics of these rivers are described. The variation in the concentration of heavy metals during recent years (data up to 1996) has been determined. The total annual quantity of some pollutants and their percentage distribution are presented. Conclusions are made based on the variation of water quality of the rivers and their impact on the heavy metal pollution of the Black Sea.
