The influence of historic mining and urbanization on geochemical and bacteriological characteristics of the Gradna Stream, Samoborska Gora Mts., Croatia
The purpose of this study is to estimate the environmental impact of the siderite–polysulfide–barite–hematite Rude historical mining site as well as the influence of the urbanization on the quality of the draining streams. The Rude deposit is drained by the Gradna stream. According to obtained geochemical and bacteriological parameters the Gradna stream is divided into four segments: 1) The headwater (decreased pH, high Eh, low concentration of nitrogen and phosphorous species, metals and bacteria) ; 2) The segment between headwater and the historical mining site (uniform pH, gradual decrease in Eh and increase in NO3-, NH4+ and PO43- concentrations) ; 3) The Rude historical mining site (slightly lower pH, high Eh, low NO3-, NH4+ and PO43- concentrations, sudden increase in metals concentration in water and decrease in adsorbed metals) and 4) The segment between the mining site and the mouth is under strong influence of the urbanization (decreased Eh, increased NO3-, NH4+ and PO43- concentrations, increased bacterial content) whereas influence of the historical mining site is diminished.
