“…Processing of sulphide-rich ores produces large quantities of pyritic wastes (Langmuir 1997;Marszatek and Wąsik 2000). Because of finer grain size (0.2 mm, Kuyucak 2002) and large surface area, a large portion of these tailings are exposed to the atmosphere.…”

Due to geochemical similarity between arsenic and sulphur, polymetallic sulphide deposits and pyrite/ arsenopyrite-bearing coal beds often contain exceptionally high concentrations of arsenic. Arsenic release from mine waste occurs after oxidative dissolution of sulphide minerals. Both arsenite and arsenate forms coexist in many mine drainage localities, with the latter oxidation state more common. The rate of arsenite oxidation to arsenate in such environments is mostly controlled by the availability of oxygen and arsenic-oxidizing microbes. Most released arsenic gets naturally attenuated within few meters downstream by adsorption and co-precipitation; amorphous precipitates such as schwertmannite or hydrous ferric oxides are better sinks than crystalline counterparts, such as goethite and jarosite. Because arsenate has a stronger affinity than arsenite for sorbents at acidic pH, arsenatedominated mine water often contains lower levels of arsenic than arsenite-dominated mine water. Secondary mineral precipitation is largely controlled by distribution of acid-neutralizing minerals, such as carbonates and aluminosilicates. In addition to natural attenuation, active and passive treatment of mine water can lower arsenic levels to meet legal limits.

“…Water pollution problems associated with mining activities are an environmental concern (Schüring et al 1997;Rösner 1998;Castro and Moore 2000;Gabler and Schneider 2000;Marszalek and Wasik 2000;Schemel et al 2000;Armienta et al 2001). In Portugal, only a few studies have been reported on environmental pollution associated with mining (Nascimento et al 1996;Oliveira 1997;Oliveira et al 1998;Antunes 1999;Antunes et al 2001;Oliveira et al 2002;Silva et al 2003), and none deals particularly with uranium mines.…”

The Vale de Abrutiga uranium deposit, located in Central Portugal near the Aguieira dam reservoir, was surface mined. Low-grade ore and waste rock were deposited on permeable ground, close to the mine, and were not revegetated. A lake has formed in the open pit. Surface waters draining the mine site are acidic, have high conductivity, and high concentrations of U, SO42-, Zn, Fe, Mn, Ra, Cu, Th, and Pb. The groundwater and the water from the reservoir cannot be used for human consumption or irrigation. The sampled waters show higher contaminant concentrations in winter than in summer. Stream sediments have high geoaccumulation indices for U, Fe, Ag, Zn, Cr, Co, and Pb. In general, sediments bordering the dam reservoir have higher metal contents in winter than in summer.

“…Flotational sludge was deposited, and the smelted ore was used later for the industrial production of arsenic trioxide. The mine has been closed for economic reasons since 1961 (Marszałek and Wąsik 2000;Przylibski 2001;Chlebicki et al 2005).…”

“…Gold and arsenic mining is one of them, and since Au occurs in ore together with As, the soil and water in mine surroundings contain increased concentrations of this element, as well as many accompanying heavy metals Peterson 1975, 1977;Marszałek and Wąsik 2000;Anawar et al 2008). Traditional remedies for contaminated soil are costly and can only affect its upper layers.…”

Here we present results of a survey conducted to identify and characterize spontaneously growing arsenic-tolerant plant species of the area around the old arsenic/gold mine in ZlotyStok (Poland), with respect of their potential use in phytoremediation. Plants and soil from their rhizosphere were sampled and analyzed for concentrations of As and accompanying Mn, Fe, Mg, Ca, Al, Cu, Zn, Ba, Pb, Ni, Cs, V, Cr, Sr, Rb, Bi, Mo and U. The soil contained primarily very high As, Pb and Al concentrations (up to 7,451, 1,058 and 31,272 mg/kg respectively). The ability of identified species to modify the amount of bioavailable arsenic in their rhizosphere was determined by single extractions of soil samples with the use of water, phosphate buffer, EDTA, and acetic acid. Although As-hyperaccumulators were not found, Calamagrostis arundinaca was identified as a new species which successfully carried out the natural phytoextraction of arsenic. This plant was able to increase substantially the arsenic availability in the soil, and likely due to efficient uptake decreased the total As concentration within the root zone by around 40% relative to the reference soil. Thus, it has high potential for phytoremediation. The lowest amount of available arsenic was found in the rhizosphere of Stachys sylvatica, the species with the lowest As shoot concentration (compared with other plant species). It was proposed as a good candidate for phytostabilization.
