Lead concentrations in surface soils of 44 urban parks of Shanghai were determined.Results showed that Pb concentrations in the soils averaged 55.06 mg/kg,ranging from 26.4 to 174.4 mg/kg,which was 1.04-6.85 times the background value of soil Pb in Shanghai.Geoaccumulation index was used to assess Pb pollution of the surface soils.Results indicated that more than a half of the parks were light-or medium-polluted,nearly one third of the parks were not polluted,and 6 parks were medium-and medium-heavily polluted.The spatial distribution of Pb concentrations showed Pb might come from traffic and industry,and Pb concentrations were not significantly correlated to the history or duration of the parks.
