“…It is reported that there are more than 1000 abandoned mines in Korea (Kim et al, 2003), and about 100,000 to 500,000 mine sites are abandoned or inactive in the United States (Carrillo-Chavez et al, 2003). Unfortunately it appears that in some places, the dams built to retain the mine tailings have collapsed.…”

a b s t r a c tVicia faba L. seeds were grown in a pot experiment on soil, mine tailings, and a mixture of both to mimic field situations in cultivated contaminated areas near mining sites. Metals in the substrates and their translocation in root, stem and leaf tissues were investigated, including morphological responses of plants growing on mine tailings. Metal concentration -and generally bioaccumulation -was in the order: roots > leaves > stems, except Pb and Cd. Translocation was most significant for Zn and Cd, but limited for Pb. Metal concentration in root and leaf was not proportional to that in the substrates, unexpectedly the minimum being observed in the mixed substrate whilst plant growth was retarded by 20% (38% on tailings). Calcium, pH, organic matter and phosphorus were the main influencing factors for metal translocation. The ultrastructure of V. faba L. cells changed a lot in the mine tailings group: root cell walls were thickened with electron dense Pb, Zn and C particles; in chloroplasts, the number of plastoglobuli increased, whereas the thylakoids were swollen and their number decreased in grana. Finally, needleshaped crystalline concretions made of Ca and P, with Zn content, were formed in the apoplast of the plants. The stratagems of V. faba L. undergoing high concentrations of toxic metals in carbonate substrate, suggest root cell wall thickening to decrease uptake of toxic metals, a possible control of metal transport from roots to leaves by synthesizing phytochelators-toxic metal complexes, and finally a control of exceeded Ca and metal concentration in leaves by crystal P formation as ultimate response to stress defense. The geochemical factors influencing metal availability, guaranty a reduction of metal content in plant growing on mixed tailing/soil substrate as far as carbon te are not completely dissolved.

“…For example, Neves and Matias (2008) and Zhou et al (2008), among others, have considered the environmental geochemistry of one specific metal on mining sites, thallium and uranium, respectively; whereas some other authors work on the environmental geochemistry of several common AMD metals (Carrillo-Chávez et al 2003;Ramos-Arroyo and Siebe-Grabach 2006). Authors, like Moon et al (2008) and Salomons (1995), have focused on the potential acid-producing capacity of tailings; while others (Ghose and Majee 2007) have studied the hazardous airborne dust around coal mining areas.…”

The geochemical behavior of zinc, lead and copper from sulfidic tailings in a mine site with potential to generate acidic drainage (pyrite (55%) and sphalerite (2%)) is reported in this paper. The mining area is divided in two zones, considering the topographic location of sampling points with respect to the tailings pile: (a) outer zone, out of the probable influence of acid mine drainage (AMD) pollution, and (b) inner zone, probably influenced by AMD pollution. Maximum total ions concentrations (mg/L) measured in superficial waters found were, in the outer zone: As (0.2), Cd (0.9), Fe (19), Mn (39), Pb (5.02), SO4(2-) (4650), Zn (107.67), and in the inner zone are As (0.1), Cd (0.2), Fe (88), Mn (13), Pb (6), SO4(2-) (4,880), Zn (46). The presence of these ions that exceeding the permissible maximum limits for human consume, could be associated to tailings mineralogy and acid leachates generated in tailings pile.

“…This may be due to reducing the mobility of the metals under high-pH conditions. Carrillo-Chávez et al (2003) also reported that soils developed from AuAg mineralization associated with carbonate minerals contained relatively low levels of heavy metals. Although there are a few carbonate minerals associated with base metals such as azurite (Cu 3 (CO 3 ) 2 (OH) 2 ), cerussite (PbCO 3 ) and smithsonite (ZnCO 3 ), most of mines mineralized by Au-Ag and base metals in Korea are associated with sulfide minerals, including pyrite (FeS 2 ), chalcopyrite (CuFeS 2 ), galena (PbS) and sphalerite (ZnS) (Geological Society of Korea 1988).…”

“…Mining and milling operations, together with grinding, concentrating ores, and disposal of tailings, are an obvious source of heavy metal contamination (Adriano 2001;Alloway 1995). Thus, elevated levels of heavy metals in soils are found in and around metalliferous mines due to the discharge and dispersion of mine wastes into the ecosystem (Fuge et al 1989;Yukselen and Alpaslan 2001;Carrillo-Chávez et al 2003). Nriagu and Pacyna (1988) estimated that median values of worldwide emission of trace metals into soils in 1983 (10 6 kg year À1 ) were 22, 954, 796, and 1,372 for Cd, Cu, Pb, and Zn, respectively.…”

The objective of this study was to investigate heavy metal contamination and geochemical characteristics of mine wastes, including tailings, from 38 abandoned mines classified as five mineralization types. Mine waste materials including tailings and soils were sampled from the mines and the physical and chemical characteristics of the samples were analyzed. The particle size of tailings was in the range of 10-100 microm. The pH of the waste covered a wide range, from 1.73 to 8.11, and was influenced by associated minerals and elevated levels of Cd, Cu, Pb, and Zn, extracted by a Korean Standard Method (digestion with 0.1 mol L(-1) HCl), which were found in the wastes. Half of the samples contained heavy metals at levels above those stipulated by the Soil Environmental Conservation Act (SECA) in Korea. In addition, extremely high concentrations of the metals were also found in mine wastes extracted by aqua regia, especially those from mines associated with sulfide minerals. Thus, it can be expected that trace elements in mine wastes may be dispersed both downstream and downslope through water and wind. Eventually they may pose a potential health risk to residents in the vicinity of the mine. It is necessary to control mine wastes by using a proper method for their reclamation, such as neutralization of the mine wastes using a fine-grained limestone.
