Abstract:The four step procedure developed by the European Community Bureau of Reference (BCR) is the optimum means of identifying heavy metal fractions in sewage sludge samples. Using the BCR procedure enables to get the date basing on which one can calculate metal stability index which supplies information on the strength of metal bonds with mineral organic soil components. Unfortunately, very popular formulae describing this index do not possess any theoretical justification and do not generate all values in the range of [0; 1]. Hence, in this paper one has presented new formulae describing not only the stability index but also a strictly connected with it the mobility index. In addition, one has suggested that these new formulae depend on the Equivalent Population (EP) indicator.

“…[1][2][3][4][5][6]. In this context, such parameters as the redistribution index and reduced partitioning parameter were evaluated for the quantification of the redistribution processes of heavy metals in both contaminated [7] and uncontaminated [8] soils. Moreover, the sequential extraction methods are suitable for an evaluation of element distribution into individual soil fractions after experimental soil amendment by potential risk elements [9] as well as for evaluation of remediation potential for these elements [10].…”

A comparison of sequential extraction procedures for fractionation of arsenic, cadmium, lead, and zinc in soil

et al. 2005

Twelve soil samples differing in physicochemical properties and total element contents were extracted by three sequential extraction procedures to determine As, Cd, Pb, and Zn bound to individual soil fractions and are defined by individual operational procedures. In the case of arsenic, two additional sequential extraction schemes were designed entirely for fractionation of soil containing arsenic were tested. The results confirmed that determination of element proportions bound to individual soil fractions is strongly dependent on the extracting agent and/or procedure applied within individual extracting schemes. As expected, absolute values of the elements released among the individual extracting procedures are weakly comparable. More reliable results were determined for the more mobile soil elements i.e. cadmium and zinc, in the fractions characterizing the most mobile proportions of investigated elements where significant correlations with basic soil characteristics were observed. In contrast, ambiguous results were observed for As and Pb, for both the individual extraction procedures and the effect of the soil characteristics. Regardless of the studied element, the poorest results were determined for reducible and oxidizable soil fractions. The application of at least two independent procedures or modification of the extraction scheme according to element investigated and/or particular soil characteristics can also be helpful in definition of element pattern in soils in further research.

“…The five-step sequential extraction procedure (SEP) was originally developed by Tessier et al (1979) for sediment samples dominated by quartz, plagioclase and K-feldspar. This procedure was extensively used for metal partitioning in sediments and soil into five fractions previously mentioned by Kaasalainen and Yli Halla (2003), Han et al (2003) and Abollino et al (2006). An operational three-step SEP for fractionation of Cd, Cr, Cu, Ni, Pb and Zn in sediment proposed by the European Community Bureau of Reference (BCR)-Institute for Reference Materials and Measurements IRMM Geel, Belgium (Quevauviller, 1998) was used by Bougriet et al (2007) for the chemical fractionation of metals in sediments from the Deule-canal affected by discharges from a smelter.…”

A preliminary study on soil contamination with heavy metals and As based on solid phase speciation according to the Tessier scheme and the influence on groundwater in an area under anthropogenic influence (Bozanta -Baia Mare, Romania) was conducted. The partitioning of Al, As, Cd, Cu, Fe, Mn, Pb and Zn in five fractions is discussed in relation to soil characteristics, pH, organic matter content, mineralogical composition and distribution of the same elements in airborne particulate matter. The airborne particulate matter contains high quantities of As, Cd, Cu, Pb and Zn as exchangeable fraction. The sequential extraction carried out on soil samples revealed the main role of Fe -Mn oxides surface in the immobilization of metals. Organic matter has a specific role in complexation of Cu, Pb, As and Al, since high contents of these metals were recovered in the oxidizable fraction. Cadmium has a high selectivity for carbonate minerals. The amendment of soil with natural fertilizer increases the exchangeable fraction of metals with the highest toxicity. The available fraction for plants (exchangeable þ carbonate-bound species) exceeded the alert values in soil, therefore the continuous monitoring of the area is necessary. The soil is unsuitable for agricultural use due to high contamination on surface with toxic elements resulted from anthropogenic activities. Groundwater is contaminated with very toxic elements (As, Cd and Pb) but also with Cu, Mn and Zn and is unsuitable as supply for drinking water.
