Identifying Controlling Factors of Bioaccumulation of Selected Metal(loid)s in Various Soil–Cereal Crop Systems within Cultivated Fluvisols

The paired Fluvisol and cereal samples in both the field screening controlled experiments are reported to elucidate soil–crop relationship for As, Cd, Pb relation changing contamination levels. Significant varietal differences plant uptake were observed crop type (barley, triticale) harvested part of (oat shoots grain). When parametrizing stepwise regression models, inclusion soil properties often improved performance models but diverse critical parameters retained model individual metal(loid)s. pH value was a statistically significant variable Cd uptake. For As Pb, more successful fit achieved using indicators quantity or quality organic matter, always with lower inherent reliability compared Cd. Further, single correlation analysis used investigate between extractable metal concentrations solution their accumulation. there strong intercorrelations among extractions, NH4NO3 extraction stood out perfect experiments. CaCl2 Na2EDTA solutions outperformed other extractions better choice assessment depositional fluvial substrates.
