Volume magnetic susceptibility of soils and alluvial sediments from the eastern Pomeranian region near Gdańsk was investigated. Full set of geochemical analyses had been previously performed for all the samples studied. The results are presented in the form of the susceptibility maps of the topsoil horizon, the subsoil at the depth between 40 and 60 cm and the alluvial sediments. Additionally the differential susceptibility map between topsoil horizon and the subsoil at the depth 40-60 cm has been also constructed. A close correlation is observed between positive anomalies of differential susceptibility and urban areas. This is interpreted as surface anthropogenic pollution. Magnetic susceptibility values higher than 1200 x 10-6 SI units, observed in topsoil horizon, might reflect high contents of such elements as Ba, Co, Mg, Mn and Ni.
