AB  - The spatial distribution of persistent organic pollutants (POPs) was examined in 
      soils surrounding the Tanggu Chemical Industrial District in Tianjin, China. The 
      concentrations of hexachlorocyclohexanes (HCHs), dichlorodiphenyltrichloroethanes 
      (DDTs), hexachlorobenzenes (HCBs), and polychlorinated biphenyls (PCBs) were 
      determined in 70 surface soils using accelerated solvent extraction and gas 
      chromatography with electron capture detection. The results showed that the 
      ranges of  summation operatorHCH,  summation operatorDDT, SigmaHCB, and  summation operatorPCB concentrations in soils were 2.1-12,549 mug 
      kg(-1) (average, 965 mug kg(-1)), n.d.-2,033 mug kg(-1) (average, 88.4 mug kg(-1)), 
      n.d.-1,924 mug kg(-1) (average, 349 mug kg(-1)), and n.d.-373 mug kg(-1) (average, 
      46.2 mug kg(-1)), respectively. Of these, HCHs were the dominant POPs, accounting 
      for 75 % of the total organochlorine pesticide (OCP) residues. Overall, the 
      spatial distribution of OCP concentrations showed a decreasing trend from the 
      center of the Tanggu District to the surrounding areas. Two major pollution 
      sources were Tianjin Dagu Chemical Co., Ltd. in the district center and the 
      Tianjin Chemical Plant in Hangu District. In contrast, PCB concentrations were 
      relatively high in the Haihe estuary to the east and low to the west of the study 
      area. Component analysis of OCPs in these soils showed that they mainly came from 
      industrial point sources. Compared with soils in other regions, soil DDT 
      pollution was at a medium level in the Tanggu Chemical Industrial District, but 
      associated HCH, HCB, and PCB pollution was relatively heavy. By multivariate 
      statistical analyses, Tianjin Dagu Chemical Co., Ltd. was recognized as the main 
      source of POPs, and soil properties were clarified to play an important role on 
      the distribution and composition of POPs, especially the organic carbon content.
