Abstract The BCR EUR 14763 EN sequential extraction method, developed for the analysis of heavy metals in sediments, was applied to 35 soil samples covering the area of the Czech Republic. The soils varied in their physical-chemical properties and total element contents. While the residual fraction in the case of cadmium was only 18% of total Cd, for Zn and As the residual fraction was dominant (55 and 75%, respectively). The decreasing concentrations of extractable elements in the order Cd 〉 Zn 〉 As correspond to their availability in plants. The influence of selected soil properties (pH, sorption capacity, organic matter, and clay-silt-sand content) on the distribution of As, Cd and Zn was evaluated.
