TI  - Trends of Diverse POPs in Air and Water Across the Western Atlantic Ocean: Strong 
      Gradients in the Ocean but Not in the Air.

AB  - Oceans have remained the least well-researched reservoirs of persistent organic 
      pollutants (POPs) globally, due to their vast scale, difficulty of access, and 
      challenging (trace) analysis. Little data on POPs exists along South America and 
      the effect of different currents and river plumes on aqueous concentrations. 
      Research cruise KN210-04 (R/V Knorr) offered a unique opportunity to determine 
      POP gradients in air, water, and their air-water exchange along South America, 
      covering both hemispheres. Compounds of interest included polychlorinated 
      biphenyls (PCBs), organochlorine pesticides (OCPs), polybrominated diphenylethers 
      (PBDEs), and polycyclic aromatic hydrocarbons (PAHs). Remote tropical Atlantic 
      Ocean atmospheric concentrations varied little between both hemispheres; for HCB, 
      BDEs 47 and 99, they were  approximately 5 pg/m(3), PCBs were  approximately 1 pg/m(3), alpha-HCH was  approximately 0.2 
      pg/m(3), and phenanthrene and other PAHs were in the low 100s pg/m(3). Aqueous 
      concentrations were dominated by PCB 52 (mean 4.1 pg/L), HCB (1.6 pg/L), and 
      beta-HCH (1.9 pg/L), with other compounds <1 pg/L. Target PCBs tended to undergo net 
      volatilization from the surface ocean, while gradients indicated net deposition 
      for a-HCH. In contrast to atmospheric concentrations, which were basically 
      unchanged between hemispheres, we detected strong gradients in aqueous POPs, with 
      mostly nondetects in the tropical western South Atlantic. These results highlight 
      the importance of currents and loss processes on ocean scales for the 
      distribution of POPs.
