ABSTRACT
The aim of this study was estimation of bioaccumulation of heavy metals (Pb, Ni, Cu, Zn, Cd) in forage grasses from the area of Podlasie Province based on the bioaccumulation factor. In the soil samples the pH, organic carbon content and CEC were determined. Determination of heavy metals contents in plant and soil material was carried out by flame atomic absorption spectrometry. Soils were characterized mainly by acidic reaction, high cation exchange capacity and organic carbon content. The content of heavy metals in studied forage grasses did not exceed the polish regulations related to plant usage for feeding purposes, except the lead content in seven samples. Coefficients of variation for particular heavy metals content in studied forage grasses were as follows: Pb - 37%, Ni - 63%, Cu - 30%, Zn - 34%, Cd - 48%. The highest bioaccumulation factor was found for nickel and grass from the village Remieńkiń (11.54), while the lowest for cadmium and grass from the village Jemieliste (0.04).
