“…The values of the UCL [median + 2 SDEV] were appointed as the upper limit of background variation. It was suggested as ''threshold level'' for soil cleanup goals of environmental legislation (Reimann et al 2005) and are adopted to identify the outliers of each element (Matschullat et al 2000, Reimann et al 2005. The values under the UCL [median -2 SDEV] were appointed as regional background level (BCL).…”

(2010 -2014 survey). The geographical distribution maps of the elements over the sampled territory were constructed using GIS technology. The concentrations of Cr, Ni, Pb and Zn were higher than the respective median values of Europe, suggesting that the zones with heavy vehicular traffic and industries emission input are important emitters of these elements. Selected zones are highly polluted particularly by Cd, Pb, Hg and Ni. The statistical analyses revealed that a strong correlation exists between the Pb and Cd content in mosses and the degree of pollution in the studied sites were assessed.

“…The values that lie outside of this range (the so-called outliers) are considered either negative or positive geochemical anomalies. Of different statistical techniques that have been used for evaluation of geochemical background ranges (Matschullat et al 2000;, the iterative 2r-technique was found plausible and realistic (Matschullat et al 2000). This simple technique is based on the assumption that all values beyond the mean ±2r are omitted from the dataset and the new mean ±2r range is calculated using the reduced data.…”

“…Since 2000, many authors have discussed the issues related to geochemical background and have proposed different methods of its evaluation (Matschullat et al 2000;Li et al 2003;Gałuszka 2006Gałuszka , 2007Gałuszka and Migaszewski 2011;Gustavsson et al 2012;Rékási and Filep 2012). However, only very few publications have considered geochemical background of metals in soils of post-mining sites (Loredo et al 2006;Teršič et al 2009).…”

Geochemical background of potentially toxic trace elements in soils of the historic copper mining area: a case study from Miedzianka Mt., Holy Cross Mountains, south-central Poland

The aim of this study was to evaluate the geochemical background and spatial distribution patterns of selected trace elements (As, Cd, Cr, Cu, Mn, Ni, Pb, U and Zn) in 62 surface soil samples collected in the historic Cu mining area (Miedzianka Mt., Holy Cross Mountains, south-central Poland). In the study area the mining activity dates back to the fourteenth century. After the shutdown of mining operations in 1953, the soil was not remediated and neither its mineralogy nor chemistry was examined. The examined soils showed a high variability in the element concentrations. The threshold values defined as the upper limits of geochemical background range (mg kg -1 in parentheses) were Cr (63), Mn (2156), Ni (39), Cu (52), Zn (175), As (36), Cd (2), Pb (73) and U (1.9). A high percentage of the samples exhibited trace element concentrations above the upper limit of the geochemical background range. The threshold values were evaluated in this study with application of the iterative 2r-technique. All of these values exceeded the standards recommended for soils in protected areas of Poland. The sampling points with anomalous concentrations of potentially toxic trace elements were located mostly in southern and western parts of the study area close to the sites of former mining activities. Very high concentrations of As, Cr and Ni at several sites may adversely influence the environment. High positive correlations between all the determined elements may be indicative of a common geogenic source of these elements and their geochemical affinity.

“…Our method is based on the analysis of at least several plant samples and this gives an opportunity to use chemometrics for establishing the typical foliar concentrations of elements in plants growing in the study area. For this purpose, we propose that the iterative 2r-technique be used (Matschullat et al 2000). This technique is frequently employed for calculation of geochemical background.…”

A vulnerable point of the currently used approach to the search for the new species capable of abnormal accumulation (hyperaccumulation) of trace elements is that most studies have been conducted in laboratory conditions and focused on the determination of a limited number of elements. We propose a methodology that enables screening for multi-element accumulating plants. This methodology is based on two analytical steps: a semiquantitative analysis mode by ICP-MS that allows selection of plant samples which are enriched in one or more trace elements, and a quantitative analysis necessary for confirmation of the results derived from the first step. The proposed methodology was tested in the study of 30 plant samples. Ten elements with the highest concentrations obtained in the semiquantitative analyses were determined quantitatively with the following detection limits (in mg/kg): 0.001 for Ag, 0.08 for Ba, 0.002 for Cd, 0.005 for Co, 0.01 for Cr, 0.003 for Cu, 1.4 for Fe, 0.012 for Mn, 0.03 for Ni, 0.006 for Pb, 0.001 for Sc, 0.001 for Tl and 0.06 for Zn. The CRM recovery values obtained were in the range of 80-103 %, and the precision of the measurements (as RSD) was in the range of 0.34-4.05 %. We also propose a simple method for evaluation of typical element concentrations in plants collected for analyses. Our approach provides a novel screening method for both identification of new hyperaccumulators and for studying a larger number of elements accumulated by plants. This method may find its application in environmental biotechnology.
