Urban geochemistry: Sisak in Croatia, a long-lasting historical, urban and industrial city

An urban geochemical research was carried out in the Sisak city and its surroundings to determine the concentration, spatial distribution and sources of the elements in the soil. Composite samples were taken in the topsoil layer (0 -10 cm). Multivariate statistics was performed for clarifying the element sources in this layer. Factor analysis yielded 8 factors: 4 anthropogenic, 2 geogenic and 2 mixed ones. The main influence at the urban and rural soils composition was by parent material and anthropogenic input in the old part of the city, along roads and railways and in the industrial areas. The results pointed out that soils are very good sink for collecting and accumulating trace elements in the long-lasting urban and industrial areas.
