AB  - Polychlorinated biphenyl (PCB) and organochlorine pesticide (OCP) were analyzed 
      in surficial sediments from the Haihe River and Haihe Estuary Area, Tianjin, 
      China. The concentrations of [summation operator]PCBs (the sum of 32 PCB 
      concentrations) and [summation operator]OCPs (the sum of eight OCPs 
      concentrations) in the sediments from this area ranged from n.d. (not detected) 
      to 253 ng g(-1) (average value: 66.8 ng g(-1)) and from 0.997 to 2447 ng g(-1) 
      (average value: 738 ng g(-1)), respectively. Among the OCPs, the range of 
      concentrations of hexachlorocyclohexane and its isomers (HCHs), 
      dichlorodiphenyltrichloroethane and its metabolites (DDTs) and hexachlorobenzene 
      (HCB) were 0.997-1620 ng g(-1) (547 ng g(-1)), n.d. - 155 ng g(-1) (18.5 ng 
      g(-1)) and n.d. - 835 ng g(-1) (173 ng g(-1)), respectively. In general, the 
      concentrations of all persistent organic pollutants (POPs) from the Haihe River 
      were higher than those from the Haihe Estuary Area. Compositional analyses of the 
      POPs indicated that tri-PCBs were dominant in sediment from the Haihe River, 
      while tetra-PCBs and penta-PCBs were identified as being prevalent in the Haihe 
      Estuary Area. In addition, beta-HCH and p,p'-DDD were found to be the dominant 
      HCHs and DDTs, respectively. Compared with other areas around the world, the 
      concentrations of POPs in sediments from the Haihe River were higher, but 
      pollution level was comparable with other areas in the Haihe Estuary Area. 
      According to established sediment quality guidelines (SQGs), POPs in this area 
      have potential ecological risk.
