AB  - Little is known of the distribution of persistent organic pollutants (POPs) in 
      the deep ocean. Polyethylene passive samplers were used to detect the vertical 
      distribution of truly dissolved POPs at two sites in the Atlantic Ocean. Samplers 
      were deployed at five depths covering 26-2535 m in the northern Atlantic and 
      Tropical Atlantic, in approximately one year deployments. Samplers of different 
      thickness were used to determine the state of equilibrium POPs reached in the 
      passive samplers. Concentrations of POPs detected in the North Atlantic near the 
      surface (e.g., sum of 14 polychlorinated biphenyls, PCBs: 0.84 pg L(-1)) were 
      similar to previous measurements. At both sites, PCB concentrations showed 
      subsurface maxima (tropical Atlantic Ocean -800 m, North Atlantic -500 m). 
      Currents seemed more important in moving POPs to deeper water masses than the 
      biological pump. The ratio of PCB concentrations in near surface waters 
      (excluding PCB-28) between the two sites was inversely correlated with congeners' 
      subcooled liquid vapor pressure, in support of the latitudinal fractionation. The 
      results presented here implied a significant amount of HCB is stored in the 
      Atlantic Ocean (4.8-26% of the global HCB environmental burdens), contrasting 
      traditional beliefs that POPs do not reach the deep ocean.
