“…Trace metals interact with sediment matrix through different binding mechanisms, including adsorbed to mineral surfaces, associated with carbonates, Fe/Mn oxyhydroxides, organic matter, sulfides and the lattice of refractory crystalline minerals, such as silicates (Das et al, 1995;Tack and Verloo, 1995;Gleyzes et al, 2002;Sahuquillo et al, 2003). The mobility of trace metals in sediments is environmentally dependent on and controlled by several factors: the sediment type on the basis of the parameters that affect metal interaction, basically pH, cationic exchange capacity, nutrient status, carbonates and organic matter contents, redox potential and texture; the nature of the contamination in terms of origin and characteristics of deposition and composition; the environmental conditions that may lead to weathering, such as acidification, redox processes, temperature and water regime (Sahuquillo et al, 2003).…”

“…From these studies it has emerged that total soil metal content alone is not a good measure of short-term bioavailability and not a very useful tool to determine potential risks from soil contamination (Tack et al, 1995;Sauvé et al, 1998). In fact, since plants take up most nutrients from the soil pore water, it is often assumed that the dissolved potentally toxic elements (PTE) are readily available to organisms (Barber, 1984;Vig et al, 2003).…”

Chemical elements that are either present naturally in the soil or introduced by pollution are more usefully estimated in terms of 'availability' of the element, since it is this property that can be related to mobility and uptake by plants. A good estimation of 'availability' can be achieved by measuring the concentration of the element in soil pore water. Recent achievements in analytical techniques allowed to expand the range of interest to trace elements, which play a crucial role both in contaminated and uncontaminated soils and include those defined as potentially toxic elements (PTE) in environmental studies. A complete chemical analysis of soil pore water represents a powerful diagnostic tool for the interpretation of many soil chemical phenomena relating to soil fertility, mineralogy, and environmental fate. This chapter describes some of the current methodologies used to extract soil pore water. In particular, four laboratory-based methods, i) high speed centrifugation-filtration, (ii) low (negative-) pressure Rhizon™ samplers, (iii) high pressure soil squeezing and (iv) equilibration of dilute soil suspensions, are described and discussed in detail. A number of operational factors are presented: pressure applicable (i.e., pore size involved), moisture pre-requisites of the soil, pore water yielding, efficiency, duration of extraction, materials and possible contaminations for PTE studies. Some consideration is then taken to assess advantages and disadvantages of the methods, including costs and materials availability.

“…Consequently, hundreds of operationally defined sequential extraction methods have Fig. 1 Location of the investigated site on the map of Europe been described that recognize the main soil components that bind metals in soils (Tessier et al 1979;Zeien and Bruemmer 1989;Tack and Verloo 1995;Gleyzes et al 2002;Pueyo et al 2003;Rao et al 2008;Hass and Fine 2010). To quantify the contributions of particular fractions, chemical solutions of varying strength and reactivity are applied to soils in order to release metals bound to different soil components.…”

“…Consequently, the distribution of trace metals in soil profiles, together with data on their speciation in the soil solid phase, provides valuable information on the origin of metals, as well as on the factors and mechanisms responsible for their increased mobility and related bioavailability. Speciation of trace elements in soils was defined by Tack and Verloo (1995) as the identification and quantification of the different, defined species, forms, or phases in which an element occurs.…”

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.
