“…In fine-grained fractions gypsum and iron oxides and hydroxides are very common. The occurrence of gypsum in carbonate soils has been induced by products of pyrite weathering as a result of carbonate dissolution and hydrolysis of Ca-bearing minerals and desorption of exchangeable Ca (Martín et al 2008). The results of these XRD measurements are similar to those reported by Uzarowicz (2013) in a soil sample collected from a depth interval of 0.03-0.3 m close to site R58 in the current study.…”

“…The process of sulphide oxidation in soils is rapid as shown by the study of Martín et al (2008). These authors observed a substantial drop in pH to a value close to 2 after 3 years of experimental deposition of pyrite tailings over a carbonate soil.…”

“…However, the soil pH as a major factor affecting element mobility and cation exchange capacity at extremely acidic sites (pH \ 4) may be responsible for soil infertility (Fig. 2) due to partial hydrolysis of primary silicates (Martín et al 2008) and increased bioavailability of phytotoxic metal(loid)s (Romero-Freire et al 2016). The highest concentrations of trace elements have been found in samples revealing circumneutral pH (except for sample R55).…”

“…The presence of gypsum and porous Fe oxides and hydroxide assemblages in Rudki soils gives evidence for weathering of iron sulphides (pyrite and marcasite) that occur in the parent rock (Uzarowicz 2013). Authigenic formation of different secondary Fe minerals (iron oxyhydroxides, jarosite) have been reported in many studies of carbonate soils influenced by sulphide weathering (Martín et al 2008;Navarro et al 2008;Lara et al 2015).…”

Spatial distribution patterns of As, Ba, Cd, Cr, Cu, Mn, Ni, Pb, U and Zn were determined in topsoil samples collected after 40 years of chemical remediation conducted in the inoperative ''Staszic'' pyrite-uranium mine in the Holy Cross Mountains, south-central Poland. Soil samples were taken from 58 sites using a systematic random sampling design. Selected samples were subjected to an X-ray diffractometry analysis on bulk soils and separated clay fractions. Hematite, goethite and gypsum are common mineral phases in soil samples. Technogenic soils developed on reclaimed mine spoils show uniform spatial element distribution patterns and additionally a distinct enrichment in As, Pb, Mn, U and Zn. Mineral and chemical composition of soils vs. rocks points to the lithogenic source of the determined elements. The results of chemical analysis have been used for evaluation of geochemical background of trace elements in the study area with the iterative 2r-technique. This investigation shows that using mean crustal element concentrations (Clarke values) as proxies of threshold values in soils are not useful for determination of strongly positive geochemical anomalies. A modified enrichment factor, i.e. a local enrichment factor, is proposed for identification of sites where soils are contaminated.

“…The mineralogical study of the most polluted soils in the affected area Martín et al, 2008) , suggesting that the removal of As through co-precipitation and adsorption reactions is probably the dominant solid-phase control on the mobility of arsenic (Bigham et al, 1996;Dold, 2003;Sánchez España et al, 2005). In this way, the retention of As in these soils would be related to the precipitation of relatively stable forms www.intechopen.com of ferrihydrite and schwertmannite; this process is related to the reduction of soluble As concentrations in soils (Carlson et al, 2002;Courtin-Nomade et al, 2003).…”

Long‐term assessment of remediation treatments applied to an area affected by a mining spill in Spain

This study evaluated the effectiveness of remediation treatments in the long-term (20 years) for one of the largest mine spills in the world, the Aznalcóllar accident. Soil recovery was carried out through the application of various rates of organic (compost and manure) and inorganic amendments (materials rich in iron oxides and calcium carbonate). Different amendment combinations were grouped in four treatments (T1 to T4) and applied in different sectors depending on the soil properties and the degree of initial contamination. To assess the degree of soil recovery, physicochemical properties, total, water-soluble, and bioavailable concentrations of the main contaminants (Pb, As, Zn, and Cu) were determined over time. Applied treatments increased pH, calcium carbonate, and organic carbon content of soils, reduced electrical conductivity, and decreased mobility of contaminants, indicating that remediation treatments were efficient recovering soils contaminated by potentially harmful elements (PHEs).However, 20 years after the accident, total concentrations of Pb and As still exceed the intervention levels of the current regulations in certain areas. These areas are located in the sectors closest to the mine and where treatments T1 and T2 were applied. In these cases, the added doses of organic amendments, iron oxide-rich soils, and carbonate amendments were not sufficiently effective, so the application of new treatments is recommended to complete the total recovery of the Guadiamar Green Corridor.
