“…Oxidized and soluble heavy metals are significant components of many industrial and residential wastes, in particular wastes from the mining and metallurgical industries, and preventing their release into the ecosystem is of great interest. Mine tailings have long been an area of interest, and there is increasing evidence that the heavy metal contaminants present in metallurgical slags, often assumed to be effectively immobilized by ferrosilicate glasses, are in fact slightly leachable and therefore potentially problematic where slags are treated simply by dumping either in landfills or in the sea [1]. There are also numerous areas worldwide where soils have become contaminated with heavy metals over the past several decades, and the treatment of these soils to prevent further distribution of contaminants is becoming ever more critical.…”

“…For example Canadian guidelines classify contaminated soils according to their land use whereas Dutch guidelines provide target and intervention values. Another issue that has to be underlined is the lack of commonly used standard tests to classify wastes and leachates under specific environmental conditions [3,4].…”

“…to 1989 in the historical mining area of Lavrion, Attica, caused the accumulation of vast volumes of metallurgical wastes wich are considered to be responsible for the degradation of the environment (Marinos and Petrascheck, 1956;Konofagos, 1980;Kontopoulos et al, 1995). Stavrakis et al, (1994) and Kontopoulos et al, 1995 mention that the soils of the pit-area, but also in the surrounding area show high concentrations of Pb, Zn, Sb, Cu, Hg, Cd, As, Fe and Mn. Chronopoulos and Chronopoulou-Sereli, (1986) measured high concentrations of Pb, Zn, Cu, Fe and Mn in vegetable fibres.…”

Abstract. This work is referred to the characterization of the environmental hydrochemistry in the broader Sapes area -Thrace region, on the basis of physico-chemical properties of surface and groundwaters occurring in the volcanosedimentary formations of this area, where gold mining activities are planned to operate. Volcanic rocks are considerably altered where they are in contact with hydrothermal solutions. Aquifers are formed within these formations. Surface and ground waters are strongly metalliferous and their hydrochemical facies present similar but complex water types. Certain characteristic chemical types are the following: Ca-Mg-HCO 3 -SO 4 , Ca-Mg-SO 4 -HCO 3 . Ca-SO 4 , Ca-Mg-SO 4 . Ca-Na-Cl-HCO 3 , Na-Cl. A small majority of the water samples present the following order of anion dominance HCO 3 − > SO 4 2− > Cl − . Calcium is the dominant cation. Bicarbonates and sulfate ions are the dominant anions. The order of dominance for the heavy metals in surface and ground waters is as follows: Fe > Mn > Zn > Ni > Cu. The saturation index of waters regarding minerals is low. Computer simulation indicates that calcite and dolomite are common minerals in all water samples which are saturated in respect to quartz and argillaceous-siliceous minerals. The most pronounced property of waters is their acidic character. The high metal concentrations are related to water with low pH. Sulfide minerals control the low pH values of waters which is an important control factor for the evolution of the water chemical composition. The abundance of sulfates is attributed to the dissolution of the minerals pyrite (FeS 2 ) and alunite (KAl 3 (SO 4 ) 2 (OH) 6 . The water-mineral interactions are responsible for the chemical composition of waters. Water quality problems can be successfully handled by the use factor analysis. 17 chemical parameters can be substituted by five factors which successfully represent the hydrochemical processes as well as their geographic distribution. Volcanic rocks in the study area have the potential to produce acid drainage.
