POSSIBILITIES OF ECOLOGICAL REHABILITATION OF THE AREAS AFFECTED BY COPPER EXPLOITATION ACTIVITY FROM ROŞIA POIENI PUBLISHEDMihaela Corcheş, Iacob Borza, Ioana Corcheş, Mădălina Iordache
The scope of the study is the ecological rehabilitation of the areas affected by the cupriferous exploitation from Roşia Poieni, in present being in conservation. Although the exploitation and preparation activity of the cupriferous material is stopped, the waters pollution with heavy metals is continuous, because of waters resulted from the precipitations that lave the barren dumps and the decantation lakes. The second aspect is the importance of the reconstruction of vegetation from areas affected by the pollution and the reconstruction of fertile soil layer. There were used technical data from S.C. Cuprumin Abrud, as well as hydrological data and chemical analyses made by the National Administration of Romanian Waters – System of Water Management from Alba.
