The paper presents concentrations of several heavy metals (Cu, Zn, Pb, Ni, Cd) and polycyclic aromatic hydrocarbons (PAHs) in arable soils in Poland. The above-mentioned elements were determined using the AAS method following digestion of samples in aqua regia. Approximately 97% Polish soils were characterized by natural (0°) or elevated (1°) concentrations of heavy metals and only 3% were classified as soils with high (II-V°) heavy metal contents. On the basis of initial monitoring of concentration of PAHs (determined of HPLC method) in Polish soils (216 samples taken from upper horizons), it was found that they were characterized by arelatively low levels of contamination with the above-mentioned organic xenobiotics.
