Abstract: This paper emphasizes an ascertainment over the pollution level on terrestrial and aquatic ecosystems within the past exploitation region of Calimani mountains sulphur ore. Experimental data are introduced here, concerning the transformation of the sulphur and sulphides into sulphuric acid, chemical changes that exist in the surface waters, on the refuse waste dumps and in the regions limitrophe to areas affected by the past exploitation of Calimani ore. Through the surface exploitation of materials including high quantities of sulphur and metallic sulphides, draining phenomena of the acid waters and solubilization phenomena of the heavy metals have been amplified.
