Abstract: 
From topsoil, 127 samples were collected in agricultural areas of Kosovo, which were analyzed for heavy metals (BM), by extraction with aqua-regia (pseudototal concentration), NH4OAc-EDTA (potential bioavailable) and NH4NO3 (mobile fraction). 62 % of the soil samples showed elevated Ni concentrations, whereas increased values for Pb, Cd, Zn and Cr were in 9 %, 6 %, 5 %, and 2 % of the sample set, respectively. Cu was below threshold values in all analyzed samples. In order to assess the bioavailability of heavy metals, relevant soil parameters were determined. Regarding mobile fractions of HM, only Ni was significantly influenced by its total concentrations. For most of HM in mobile fractions, soil pH significantly impacted the extracted metal amounts. On some field sites crop production may be under risk due to elevated metal concentrations in not only the pseudototal but also in the potentially bioavailable and mobile fractions.
