AB  - Sediments were sampled from different surface water bodies in Tianjin coastal 
      area, China, and persistent organic pollutants (POPs) including polycyclic 
      aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs), polychlorinated 
      biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) were measured using 
      GC/MS or GC/ECD. The purposes were to investigate the concentration levels of the 
      POPs and to assess their ecological risks. The results showed that all the 16 
      priority PAHs were detected from the 10 sediments sampled with the total 
      concentrations of the 16 PAHs ranging from 274.06 mug/kg to 2656.65 mug/kg, while 
      the concentrations of the halogenated POPs were generally low except in the Dagu 
      waste discharging river where the total concentrations of 24 OCPs, 35 PCBs, and 
      14 PBDEs were 3103.36 mug/kg, 87.31 mug/kg, and 13.88 mug/kg, respectively. In the 
      studied sediments, PAHs exhibited risks to benthonic organisms; particularly the 
      concentrations of naphthalene and/or acenaphthene exceeded their probable effect 
      concentrations in several locations. In comparison, only in the Dagu waste 
      discharging river, OCPs exhibited risks with the concentrations of heptachlor 
      epoxide and lindane exceeding their probable effect concentrations. PCBs and 
      PBDEs posed rare risks in the studied area.
