ABSTRACT

The Zlataritsa river is located in the South-western part of
Bulgaria and mouths into the Mesta river. The Zlataritsa river passes
through Eleshnitsa settlement where mining sites for exploitation and
treatment of uranium ore are located. This paper presents the river
pollution of uranium and radium as a result of mining activities in the
examined region. The data used are for three periods - during the complete
productive engagement, during the technical liquidation and after the end
of technical liquidation. The data from measurements have been processed
and analyzed. By correlation analysis is searched a relationship between
radioactive pollution observable in the water-quality sampling sites and the
discharges of the Zlataritsa river. The results are compared with the
permissible doses. The aim of this research is to estimate radioactive
pollution impact of the Zlataritsa river on the Mesta river which mouths
into the Marmara Sea through the territory of Greece.
