Several metals in urban soils of Belgrade were extracted by two methods which respectively give estimates of the available and "quasi total" contents. Soil samples were collected from six parks and three green areas within the urban zone in November, 2003 and June, 2005 on the same sites. The concentrations of Cu, Pb and Zn at several sites exceeded the limits acceptable in residential areas established by national legislation. Comparison between the 2005 and 2003 data revealed an increase of the Cu and Zn contents and a decrease of the Pb content of the urban soils. The labile phase concentration, determined as the amount of metal extracted with HCI was in the order Zn>Pb>Cu>Cd. Traffic seems to be one of the main sources of these metals, but the influence of other factors cannot be excluded.
