AB  - The concentration of PCBs in urban soils of Beijing across six land types 
      including business districts (BD), cultural and educational areas (CE), classical 
      gardens (CG), public green (PG), residential areas (RA), and roadsides (RD) was 
      investigated. The total concentrations of PCBs ranged from below method detection 
      limit (M.D.L.) to 37.11x10(-3)mgkg(-1) dry weight (mean: 11.70x10(-3)mgkg(-1); 
      median: 13.28x10(-3)mgkg(-1)), which was at a medium level compared with other 
      cities around the world. In general, the levels of PCBs decreased from the center 
      of Beijing city to the suburb, suggesting the increasing PCBs concentrations with 
      the age of the urban area. For different types of land use, the highest level of 
      PCBs was observed in CG soils which have the oldest age, and the homologue 
      profiles were similar, which were predominated by lowly chlorinated congeners 
      including di-, tri- and tetra-CBs. Principal component analysis indicated that 
      local sources such as Aroclor 1016, 1242, and 1248 were important sources in 
      addition to long-range transport of PCBs all over the world. Although the toxic 
      equivalency (TEQ) concentrations of dioxin-like PCBs in all soil samples of 
      Beijing were higher than those in other urban areas of China, they met the 
      Canadian soil quality standard.
