The purpose of this study was to investigate the influence of soil geochemistry on the concentrations of Ca, K, Mg, P, Co, Ni, Zn, Mn, Cu, and Fe in cabbage (Brassica oleracea L. var. capitata) grown on acid sulfate (AS) soils in Western Finland. A total of 11 topsoil (0-20 cm) and corresponding cabbage samples and three whole-soil profiles (≈ 0-260 cm) were collected on three agricultural fields. The concentrations of Co and Zn in cabbage were correlated with the NH 4 Acextractable (easily available) concentrations in the topsoil, indicating that the uptake of these elements in cabbage is largely governed by soil geochemistry. Yet, the concentrations of Co and Zn in cabbage were not in general elevated relative to that of Finnish average values, although some AS soils showed enriched concentrations of these metals in the soil and cabbage. Significant geochemical differences (e.g., oxidation depth, organic-matter and S content, pH) were observed among the studied AS soils, while, on the other hand, the concentrations of Ca, K, Mg, P, Ni, Mn, Cu, and Fe in cabbage were relatively similar. The hydroxylamine-extractable concentrations of these elements in the topsoil were not correlated to those in cabbage, suggesting that uptake is not governed by the oxide-bound fraction of these elements in the soil. Similarly, the easily available concentrations of Ca, P, Ni, Mn, Cu, and Fe in the topsoil were not correlated to those in cabbage, indicating that uptake is independent of the easily available concentrations in the soil. Hence, it is suggested that cabbage can regulate and thus optimize its concentrations of Ca, P, Ni, Mn, Cu, and Fe. Oxidation depth affected neither the easily available concentrations of Co, Ni, Zn, and Mn in the topsoil nor the concentrations in cabbage. However, the subsoil with a lower oxidation depth, which is to a smaller extent affected by leaching, may partly be enriched in these metals. Nevertheless, these showed no increased concentrations in cabbage. Based on these findings, it is suggested that the large amounts of metals mobilized in AS soils are easily lost to drains, subsequently contaminating nearby waterways and estuaries whereas they are only partly enriched in cabbage and other previously studied crops (oat).

“…Black shale soils, like the ones included in this study, have much in common with another soil typeacid sulfate soil-which exists abundantly on coastal lowlands worldwide (Andriesse and van Mensvoort 2006). The acid sulfate soils are, in contrast to the black shale soils, developed in soft sediments deposited in brackish or saline waters (mostly during Holocene) and containing disseminated sulfides produced by seawater sulfate reduction (Boman et al 2008). The two soil types thus have different direct origins and sulfur sources, but like the black shale soils, the acid sulfate soils have a chemistry dominated by sulfide oxidation, metal release, and acidification (Å ström 1998; Burton et al 2006a) and thus behave, in an environmental context, in a manner similar to the black shale soils (Macdonald et al 2007;Burton et al 2006b;Fältmarsch et al 2008Fältmarsch et al , 2009Boman et al 2010).…”

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.

“…AVS comprises porewater sulfides (including dissolved Fe(II)-sulfide complexes and aqueous FeS clusters) and a suite of metastable iron sulfides including the minerals mackinawite (FeS) and greigite (Fe 3 S 4 ) Morse and Rickard 2004;Rickard and Morse 2005). AVS and S 0 are generally a minor fraction of RIS in coastal marine and estuarine sediments (Giblin and Wieder 1992;Morse and Rickard 2004), but are found at appreciable proportions of RIS in organic, sulfide-rich materials from ASS landscapes (Bush et al 2004;Macdonald et al 2004;Burton et al 2006b;Boman et al 2008Boman et al , 2010.…”
