“…To determine the chemical species of heavy metals in soil, a large number of single and multiple sequential extraction procedures, which use a series of reagents to separate the soil metals into different fractions, have been developed (Tessier et al 1979;Shuman 1985;Rauret 1998;Leleyter and Probst 1999). Although the sequential extraction methods suffer from non-selectivity and trace element redistribution among phases during extraction, they are still suggested for evaluating the mobility and potentially bioavailable metal fractions in contaminated soils (Gómez Ariza et al 2000;Kabala and Singh 2001;Abollino et al 2002;Parat et al 2003;Pueyo et al 2003;Banat et al 2005;Hu et al 2006). In some research work, consistent correlations between specific metal fractions and plant metal contents were found.…”

This study was conducted to investigate the pollution load index, fraction distributions, and mobility of Pb, Cd, Cu, and Zn in garden and paddy soils collected from a Pb/Zn mine in Chenzhou City, China. The samples were analyzed using Leleyter and Probst's sequential extraction procedures. Total metal concentrations including Pb, Cd, Cu, and Zn exceeded the maximum permissible limits for soils set by the Ministry of Environmental Protection of China, and the order of the pollution index was Cd > Zn > Pb > Cu, indicating that the soils from both sites seriously suffered from heavy metal pollution, especially Cd. The sums of metal frac- tions were in agreement with the total contents of heavy metals. However, there were significant differences in fraction distributions of heavy metals in garden and paddy soils. The residual fractions of heavy metals were the predominant form with 43.0% for Pb, 32.3% for Cd, 33.5% for Cu, and 44.2% for Zn in garden soil, while 51.6% for Pb, 40.4% for Cd, 40.3% for Cu, and 40.9% for Zn in paddy soil. Furthermore, the proportions of water-soluble and exchangeable fractions extracted by the selected analytical methods were the lowest among all fractions. On the basis of the speciation of heavy metals, the mobility factor values of heavy metals have the following order: Cd (25.2-19.8%) > Cu (22.6-6.3%) > Zn (9.6-6.0%) > Pb (6.7-2.5%) in both contaminated soils.

“…The choice between the two indexes of similarities is not straightforward; in several cases, distance and correlation coefficient are used to classify samples and variables respectively [10], but this rule is not always followed. Most of the papers cited in section 2.1.2 started from Euclidean distances [11][12][13][14] or squared Euclidean distances [15][16][17][18] for clustering samples and/or variables. Some studies adopted correlations as similarity measurements for the classification of variables [10,19,20] or, less commonly, samples [21].…”

“…The fate of airborne metals in soils and their distribution in the soil profile are conditioned by soil properties and usually reflect the course of soil formation (Abollino et al 2002a;Kabata-Pendias 2011;Alloway 2013;Wang and Xu 2015). The latter are usually particularly well recorded in Podzols.…”

Purpose Here, we aimed to assess the contamination of Podzol soils in a subalpine zone of the Karkonosze Mountains. Cu, Pb, and Zn concentrations in the soil and the patterns of their speciation are discussed in relation to the possible influence of airborne industrial emissions and the stage of degradation of dwarf mountain pine stands. Materials and methods The study was conducted in the Karkonosze, a mountain range in the Sudetes, on the boundary between Poland and the Czech Republic. We examined Podzols derived from granites under dwarf mountain pine stands at two stages of degradation (without visible degradation vs. dead). These two sites were 100 m apart, at an altitude of 1400 m above sea level (upper mountain forest zone). Soil samples were collected from all distinguished soil horizons and their basic soil properties and heavy metal (Cu, Pb, and Zn) concentrations (and their speciation) determined by sequential extraction according to the method of Zeien and Brümmer. Results and discussion The Cu concentrations in these soils were relatively low, typical for soils derived from granite and did not differ considerably within soil profiles. The residual Cu fraction was a predominant one in all mineral horizons.The Pb concentrations in the surface organic horizons were clearly higher than those in similar horizons of European lowland forest soils. This distribution of Pb in the mineral horizons was apparently associated with soil colloid distribution that developed in the process of podzolization, indicating the minimum concentrations in eluvial E horizons and enhanced concentrations in illuvial Bh horizons. The organically bound fraction made up about 40% of total Pb in the Bh horizons. Zn concentrations were highest in the deepest parts of the soil, where the predominant fraction was residual, while relatively high amounts of easily mobilizable Zn were present in ectohumus.Conclusions Very high concentrations of Pb in ectohumus have most likely been caused by a long-distance transport of anthropogenic emissions. The concentrations of Pb or other metals found in soils cannot be considered to have been the principal causes of the ecological disaster observed in the Karkonosze Mountains. The highest concentrations of Pb in ectohumus, as well as its high contributions in the organically bound fraction, confirm a crucial role of organic matter in Pb accumulation in soils.
