“…The soil was collected with an auger down to 20 cm, placed in plastic containers and transported to the laboratory for preparation. The full details of sample preparation and characterization of the major elements by X-ray fluorescence method have been discussed by Pueyo et al (2005).…”

Thallium is a rare and easily dispersed element with high toxicity to organisms. Relatively high levels of thallium (approximately 9.58 mg kg(-1)) had been found in aqua regia soil extract of an accidentally polluted soil from south of Spain. To assess the available and leachable portions of thallium in the polluted soil, single and sequential extraction procedures have been utilized. Further, X-ray diffraction and scanning electron microscopic studies have also been used to find out the mineral phases. The amount of thallium extracted by the extracting agents in comparison to aqua regia, as well as the different phase associations are discussed.

“…Some workers ( Pueyo et al 2005) had given action limits for aqua regia and CaCl2 extraction procedures for a contaminated soil sample so that those samples can also be used as quality control materials (QCMs). Venelinov and Sahuquillo (2006) gave an excellent account of producing quality control materials to meet the shortage of certified reference materials.…”

A comprehensive review of the single and sequential extraction schemes for metal fractionation in environmental samples such as soil and industrially contaminated soils, sewage sludge and sludge amended soils, road dust and run off, waste and miscellaneous materials along with other approaches of sequential extraction methods are being presented. A discussion on the application of chemometric methods in sequential extraction analysis is also being given. The study of single and sequential extraction methods for various reference materials are also being looked into. The review covers several aspects of the single and sequential extraction methodologies. The use of each reagents involved in these schemes are also discussed briefly. Finally the present upto date information by different workers in various fields of environmental geochemistry along with the possible future developments are also being outlined.

“…The CaCl 2 and phosphate extraction methods were based on those proposed by Pueyo et al (2005) and Antosiewicz et al (2008), respectively. Briefly, approximately 2 g of soil sample was weighed into a centrifuge tube, and 20 mL of a 0.01-mol L −1 CaCl 2 solution (or 20 mL of a 0.1-mol L −1 KH 2 PO 4 / 0.1-mol L −1 K 2 HPO 4 solution at pH 7.2 for As extraction) was added.…”

“…Weak neutral salt solutions have been reported to be useful to evaluate the impact of trace elements on plants and soil biological activity (Kabata-Pendias 2004), and CaCl 2 and phosphate buffer has been successfully used for this purpose (Antosiewicz et al 2008;Lambrechts et al 2011;Houba et al 2000;Pueyo et al 2005).…”

“…Several studies have shown the suitability of weak neutral salt solutions as metal extractants in soils because they can be considered good models for simulating rainfall and flooding events. Although there is no established standard method for these types of studies, the use of a 0.01-mol L −1 calcium chloride solution is widely recommended for the leaching of heavy metals present in exchangeable fractions of soils (Houba et al 2000;Kabata-Pendias 2004;Pueyo et al 2004Pueyo et al , 2005Sahuquillo et al 2003;Takeda et al 2006). Similarly, phosphate or acetate solutions have been reported to be better extractants for estimating the bioavailable arsenic in contaminated soils (Anawar et al 2008;Antosiewicz et al 2008;Moreno-Jiménez et al 2010).…”

Arsenic and heavy metal (specifically Cd, Cr, Cu, Ni, Pb, and Zn) uptake, translocation, and accumulation in ten native plant species spontaneously growing in soils polluted by mining activities were studied, with a focus on future phytoremediation work in polluted soils. Plant and soil samples were collected in the vicinity of the Mónica mine (NW Madrid, Spain). Soil analysis showed the ability of native plants for growing in soils with high concentration levels of Cd, Cu, Pb, Zn, and especially As. From these elements, the highest percentage of extractable elements was found for Cd and the lowest for Pb. A highly significant correlation was observed between total and extractable element concentrations in soils, except for Cu, indicating that total concentration is the most relevant factor for element mobility in these soils. Extractable elements in soils were better correlated with concentrations in plants than total elements in soils; thus, extraction methods applied are suitable to estimate the element phytoavailable fraction in soils, which depends on the plant species and not only on the element mobility in soils. High element concentrations were found in the aboveground parts of Corrigiola telephiifolia (As and Pb), Jasione montana (Cd and Zn), and Digitalis thapsi (As, Cd, Cu, Pb and Zn). However, considering the translocation and accumulation factors, together with the concentration levels found in roots and aboveground parts, only C. telephiifolia could be considered a Pb accumulator and an As hyperaccumulator plant, which could be used for future phytoremediation work in soils polluted with As.
