The aim of the study was to determine differences in the morphology, classification and chemical properties of soils in the city of Szczecin that have been anthropogenically transformed due to their location in an urban area. Soil samples were collected from 22 drillings, with depths of up to 200 cm, in both the Old Town and some newer parts of the city. Various properties were analyzed: the texture, pH in KCl, EC, base cations, and the organic carbon content, as well as the total content of Pb, Zn, Hg, Cd, Cu, Cr, Ni, and Hg. The soils in the Old Town of Szczecin exhibited the most significant anthropogenic transformation, containing anthropogenic admix-tures and organic carbon throughout their profiles. These soils were classified as Urbic Technosols (Hyperartefactic) and Skeletic Phaeozems (Technic). The presence of numerous artefacts led to alkalization, high values of the base cations, elevated salinity, and increased content of certain heavy metals. The amounts of Zn, Hg, and Cu in these soils were approximately twice as high, and the Pb levels were seven times higher as the standards allowed by Polish law. Metal pollution in the Old Town area extended to a depth of 200 cm. The soils in the newer areas of Szczecin, which underwent less anthropogenic transformation, contained small amounts of anthropogenic admixtures up to a depth of 45 cm, which is why they did not classify as Technosols. As a result, they were less saline and alkalized, with lower base cations values. Organic carbon was present in these soils to a depth of 60 cm. Pollution with Pb, Cd, and Zn occurred only to a depth of 30 cm, indicating the contemporary origin of these pollutants. When new trees are planted in the Old Town area, consideration should be given to the species of trees that tolerate increased salinity. In newer areas of Szczecin, where salinity is low, all species of trees can be grown.
