Concentrations, Fluxes, and Residence Time of PBDEs Across the Tropical Atlantic Ocean

Popis výsledku v původním jazyce

Little is known about the fate of polybrominated diphenylethers (PBDEs) across the Oceans. Air and water were sampled using both active and passive polyethylene samplers on an east-west transect across the tropical Atlantic Ocean in 2009 and analyzed forPBDEs. Typical particle-bound concentrations of PBDEs in the surface water were low, at &lt;1 pg L-1. Truly dissolved concentrations from passive samplers were similar to 40.5 pg L-1 for BDE 47 and around 0.1 pg L-1 for BDEs 28, 99, and 100 (results from active samples were compromised). In the atmosphere, particle-bound BDE 209 dominated overall concentrations (median 1.2 pg m(-3)), followed by BDE 99 (0.13 pg m(-3)). Gas-phase concentrations based on passive samplers were 1-8 pg m(-3) for BDE 47 and&lt;= 4 pg m(-3) for BDE 99. Net air-water exchange gradients strongly favored gas-phase deposition of PBDEs into the water.
