Pre-monitoring geochemical research of the river sediments in the area of Ada Tepe gold mining site (Eastern Rhodopes)

The article depicts the geochemical properties of landscapes in Ada Tepe gold mine area before its launching. research is conducted by examining heavy metals (Cu, Pb, Zn, Co, Cr, Mn and Ni) content samples river sediments local landscapes. aims to analyse concentration launch mining. study implements coefficient Clarke concentration. deviation from background concentrations a ratio between element collected environmental value element. has scale 0 particular positive value, corresponding level enrichment sample comparison value. values are equal 1, lower 1 (dispersion) any higher than case (enrichment). obtained results display researched territory as natural area. (mg/kg, median value) chemical elements Cu (15), Zn (72), Pb (17), (461), Ni (35), Co (8) Cr (60). That reason it could be defined not impacted human activities influenced anomalies. Heavy do pollute This outcome investigated sediments.
