Application of selected separation techniques and obtained total Hg concentrations in studied plant species indicate relatively low Hg phytoavailability in studied soils. Calculated separation yields for applied separation techniques were in many cases comparable with soil-plant transfer recovery values for studied plant species. Distribution of Hg in roots of studied root vegetables showed the tendency of increasing amount of Hg from basal towards terminal part of root.
