The samples were subjected to a three stage extraction procedure proposed by the BCR. The three phases that were separated out in the following order: (1) carbonate, exchangeable, (2) Fe-Mn oxides, and (3) organic matter. Metal concentrations of soil fractions and grain samples were determined by inductively coupled plasma atomic emission spectroscopy. The wheat samples were prepared to analysis using microwave acid digestion procedure. The pseudo-total concentrations of metals were determined after aqua regia digestion. The analytical accuracy of the method was evaluated by using the Standard Reference Materials (BCR 142R Light Sandy Soil, NIST 2711 Montana Soil, and NIST 2704 Buffalo River Sediment). The sum of the metal contents obtained from the modified BCR sequential extraction procedure and pseudo-total metal contents for soil samples were used to calculate recovery values. In order to evaluate the bioavailability of metals, the relationships between the wheat-metal and soil-extractable metal concentrations were compared.en10.1007/s10661-010-1513-5info:eu-repo/semantics/closedAccessModified BCR Sequential ExtractionSoilWheat GrainBioavailabilityInductively Coupled Plasma Atomic Emission SpectroscopyContaminated SoilsMetal ContentsHeavy-MetalsCrm 601SedimentZincCadmiumSingleFractionationCertificationArticle1751-4303314Q3WOS:0002880266000252-s2.0-7995244468820499161Q2
