Assessment of Aquatic Environment Contamination with Heavy Metals from Abandoned Mines of Northwestern Romania

Abstract:

In the past 20 years most of the Romania mines have been disused, leaving serious environmental problems that can generate any time real environmental disasters. After closing the mining activities, the major problem is considered to be the presence of heavy metals in the surface water in concentrations beyond the limits allowed by the environment legislation. Quality water deterioration cause discomfort to human settlements located in the vicinity of mining areas. This paper performs the assessment of surface water contamination with heavy metal, respectively Cd, Pb, Cu, Zn, by atomic absorption spectrometry over a period of four years (2011-2014) in the area of the northwestern Romania (Oas Land). Concentration values obtained from surface water samples show that flow near the mining area and surrounding landholdings exceeding the class V of water quality according to Order no. 161/2006. Keywords: contamination, aquatic environment, mining, heavy metals
