Polycyclic aromatic hydrocarbons（PAHs） contamination in soil is an increasing problem in many countries,including China.An extensive and systematic survey has been undertaken to evaluate the PAHs contamination of urban soils and foliage at different sites in Beijing.Soil samples and plant leaves collected from campuses of universities,schools and kindergartens,public squares,fallow land and roadsides,were analyzed for 16 PAHs by a GC-MS.The foliage PAHs concentrations ranged from less than（0.080×10^-6to2.786×10^-6.The highest contaminated soil sample came from roadside.Total organic carbon（TOC） played major roles in the distribution of PAHs.There was a significantly close relationship between ∑PAHs concentrations of soil and foliage samples at each site.
