AB: The Krkonose National Park belongs to comparatively less polluted regions in the Czech Republic. Detailed investigations (magnetic parameters, magnetomineralogy, SEM) of pedozones from different depths proved the prevalence of magnetite of anthropogenic origin in the top-soil OL/OF layers. Therefore, the use of magnetic method for estimating industrial contamination in this region is fully justified. Preliminary map of top/soil magnetic susceptibility showed two areas with significantly increased values. Subsequent detailed mapping pointed to tourist centres as local sources of pollution and outlined the corresponding impact to their neighbourhood. Concentration of heavy metals (Fe, Zn, Pb, Co, Cr, Cd, As) in top soil as well as in different pedozones was determined using AAS. Comparison with vertical distribution of magnetic susceptibility enabled us to determine those heavy metals (Pb, Zn, and probably Cd), whose enhancement can be attributed with atmospheric deposition.
