The aim of the present study was to estimate the magnetic susceptibility of the boundary area ofwestern and southern Poland. The investigation was carried out in woodlands of chosen forest districts. Samples were collected selectively from the occurring genetic horizons ofpit soils. The low-field magnetic susceptibility was obtained in the laboratory using the MS2B Bartington apparatus. Heavy metal content (Fe, Zn, Pb and Cu) was analyzed using AAS method, after the mineralization in the 70% HClO4 + HNO3 solution. The magnetic susceptibility results arc very diverse and above 80% of them exceed 50· l0·-8 m3/kg, that is, a border value suggesting an occurrence ofa magnetic anomaly. Heavy metal content varies in a wide range and the highest values are observed in mountainous areas, where the impact of geological structure is visible. Obviously, the input of dust emissions is significant, what is confirmed by well and positive values of correlation coefficients between magnetic susceptibility and heavy metal content (especially lead) in the area of cluster III.
