The accumulation of some macro- (N, P, K) and microelements (Co, Cu, Mn, Zn) in urban soils has been studied by the analysis of topsoil horizon. Soil samples from the big park areas and along the main boulevards in the city of Plovdiv (Bulgaria) were collected. The chemical elements content was determined using standardized analytical methods. Data obtained showed significant differences, from a low up to excessive pollution level. The majority of investigated roadside soils recorded heavy metal loading when compared to the park soils from the same area. Generally, the K and P content was high in all soil samples and varied in the range 291.9-825.4 mg/kg for potassium and 410.5- 1216.0 mg/kg for phosphorus, respectively. Nitrogen content was not so abundant and varied from low/insufficient (14.17-19.4 mg/kg) in some park soils to medium (20.85-31.36 mg/kg) in the rest samples.
