“…The reasons for this extraction order are easily understood. EDTA is a strong chelating reagent and has been reported to remove both the organically bound metals and metals occluded in oxides and secondary clay minerals in part (Payá-Pérez et al, 1993). EDTA is a non-specific extractant, and it can extract labile and non-labile fractions (Bermond et al, 1998).…”

“…A higher concentration of 0.11 M acetic acid was used in the first step of the BCR method. Acetic acid could extract organic matter bound metals in part (Payá-Pérez et al, 1993), and acetic acid was able to release most of metals associated with calcium carbonate, and minerals (kaolinite, potassium felspar and ferrihydrite) (Whalley and Grant, 1994). DTPA was originally developed to identify near-neutral and calcareous soils with insufficient transition metals (Lindsay and Norvell, 1978).…”

Comparison of a rhizosphere-based method with other one-step extraction methods for assessing the bioavailability of soil metals to wheat

There is no method recognized as a universal approach for evaluation of bioavailability of heavy metals in soil. Based on the simulation of the rhizosphere soil conditions and integration of the combined effects of root-soil interactions as a whole, a rhizosphere-based method has been proposed. Wet fresh rhizosphere soil was extracted by lowmolecular-weight organic acids (LMWOAs) to fractionate metal fractions of soil pools, which were then correlated with the metal contents of wheat roots and shoots. The rhizosphere-based method was compared with other one-step extraction methods using DTPA, EDTA, CaCl 2 , and NaNO 3 as extractants and the first step of the Community Bureau of Reference (BCR) method. Simple correlation and stepwise multiple regression analysis were used for the comparison. Simple correlation indicated that the extractable Cu, Zn, Cr, and Cd of soils by the rhizosphere-based method were significantly correlated with the metal contents of wheat roots. For DTPA, BCR1 and EDTA methods there was a relatively poor correlation between the extractable Cu, Zn and Cd of soil and metal contents of wheat roots. Stepwise multiple regression analysis revealed that the equation of the rhizosphere-based method was the simplest one, and no soil properties variables needed to be added. In contrast, the equations of other one-step extraction methods were more complicated, and soil properties variables needed to be entered. The most distinct feature of the rhizosphere-based method was that the recommended method was suitable for acidic, neutral and near alkaline soils. However, the DTPA and EDTA extraction methods were suitable for calcareous soils only-or-only for acidic soils. The CaCl 2 , and NaNO 3 extraction methods were only suitable for exchangeable metals. In short, the rhizosphere-based method was the most robust approach for evaluation of bioavailability of heavy metals in soils to wheat.

“…Iron and manganese oxides are potentially extracted from acidic soils by DTPA (O'Connor, 1988). The high concentration of acetic acid can extract weakly organically bound metals (Payà-Pèrez et al, 1993) and most of calcium and mineral bound metals (Whalley and Grant, 1994). CaCl 2 is mainly able to extract easily exchangeable metals.…”

“…CaCl2 is frequently claimed to measure bioavailable metals since it works by exchanging Ca with metals on the exchange complex (Houba et al, 1997). On the other hand, EDTA is a synthetic chelating agent that forms strong complexes with metals associated with the sediment components throughout various ways: ion exchange, adsorbtion, organically bound, or occlusion into inorganic compounds as iron (Fe) and manganese (Mn) oxides and clay minerals (Paya-Perez et al, 1993). It is thus recently used to study trace metals mobility in soils and sediments Fangueiro et al, 2005;Manouchehri, 2006).…”
