“…1 (Nesbitt and Markovics 1997;Peng et al 2007). For the clr-transformed data, there was a particularly strong correlation between Zr and Hf (r = 0.99), indicating that these metals are maintained in the form of zircon that is highly resistant to weathering (Sudom and Arnaud 1971).…”

“…Consequently, the toxic trace elements pose a threat to local human health by entering the food chain. These kinds of issues have previously been addressed by: (1) assessing the environmental contamination caused by black shale soils distributed in different parts of the world (e.g., Lee et al 1998a, b;Pašava et al 2003;Peng et al 2007Peng et al , 2009aYu et al 2008Yu et al , 2009); (2) determining the phases and species of the toxic metals in the soils (Poňavič et al 2006;Lee et al 1998b);and (3) assessing the possible impacts on ecological systems (Lee et al 1998a;Fang et al 2002;Pašava et al 2003;Peng et al 2009a) and on human health (Lee et al 1998b;Fang et al 2002;Peng et al 2004;Poňavič et al 2006).…”

“…In the Anhua county, located within this area, the black shale is an organic-rich carbonaceous shale and/or slate of the Lower Cambrian Niutitang Formation, with strata thickness of more than 260 m (Hrgi 1972) and an age of 541-560 Ma (Mao et al 2002;Horan et al 1994). After identification of spatial relationship between prevalence of endemics and black shale (Peng et al 2004), there have been studies focusing on chemical weathering of this bedrock type (Peng et al 2004(Peng et al , 2009a, analyses of acid rock drainage (Peng et al 2009b), the environmental impacts of waste rocks Peng et al 2007), and the enrichment of toxic elements in black shale soils Yu et al 2008Yu et al , 2009Peng et al 2009a). …”

This paper examines the geochemical features of 8 soil profiles developed on metalliferous black shales distributed in the central parts of the South China black shale horizon. The concentrations of 21 trace elements and 8 major elements were determined using ICP-MS and XRF, respectively, and weathering intensity (W) was calculated according to a new technique recently proposed in the literature. The data showed that the black shale soils inherited a heterogeneous geochemical character from their parent materials. A partial least square regression model and EF(bedrock) (enrichment factor normalized to underlying bedrock) indicated that W was not a major control in the redistribution of trace metals. Barium, Sn, Cu, V, and U tended to be leached in the upper soil horizons and trapped by Al and Fe oxides, whereas Sb, Cd, and Mo with negative EF values across the whole profiles may have been leached out during the first stage of pedogenesis (mainly weathering of black shale). Compared with the Chinese average soils, the soils were strongly enriched in the potentially toxic metals Mo, Cd, Sb, Sn, U, V, Cu, and Ba, among which the 5 first listed were enriched to the highest degrees. Elevated concentrations of these toxic metals can have a long-term negative effect on human health, in particular, the soils in mining areas dominated by strongly acidic conditions. As a whole, the black shale soils have much in common with acid sulfate soils. Therefore, black shale soils together with acid sulfate soils deserve more attention in the context of metal exposure and human health.

“…The lower Cambrian black shales distributed in this region are organic-rich carbonaceous shales of the Niutitang Formation, with a strata thickness of more than 260 m (HRGI, 1972) and an age of 531 ± 24 Ma (Jiang et al, 2006;Jiang et al, 2009). Minerals of the shales include major muscovite, kaolinite, clinochlore, dolomite, calcite, quartz, organic matter and pyrite, and minor microcline, albite, limonite, opal, and gibbsite contributions (HRGI, 1972;Jiang et al, 2007a;Peng et al, 2007). The trace metals enriched within the shales generally include V, Co, Ni, Mo, U, Mn, Cu, Zn, Pb, and PGE (Mao et al, 2002;Jiang et al, 2006Jiang et al, , 2007aJiang et al, , 2007bJiang et al, , 2009Peng et al, 2005Peng et al, , 2009b.…”

The purposes of this study were to assess the influence of old mining activities on the geochemistry and quality of sediments and to identify the sites of economic elements. Thirty sites of stream sediment were sampled in the study area covered by granitic, metarhyodacitic and meta-andesitic rocks and related tuffs-hosted abandoned Au mine. The suite of chemical elements, Ag, Bi, Cd, Cu, Fe, Ga, Hg, Mn, Nb, Pb, Rb, Sb, Se, Sn, Te, Th, U, Y, Zn and Zr, pH value and total organic carbon were determined, and univariate, bivariate and multivariate statistical methods were applied. The results show that the enrichment factor (EF) is very high in the case of Te and significant also with respect to Ag, Bi, Cu, Sb, Se, Sn and Zn. Likewise, geoaccumulation indices (Igeos) varied from very highly polluted with Sn and Te, strongly to very strongly polluted with Bi and Se, and moderately polluted with Sb. The polluted sites of Ag, Bi, Sb, Se, Sn and Te were outlined using Igeos maps, and economic sites of Ag and Sn were identified by geochemical maps leading to their sources, which are likely to be mining activities and lithogenic processes. The pollutant elements may cause toxicity in stream sediments, or surface or underground water, as well as plants and animals in the area. This investigation provides an environmental baseline for future monitoring of possible human/anthropogenic, industrial and agricultural impacts on the study area and considers an attempt at re-mining Ag and Sn.
