TL;DR: Air-water exchange gradients suggested net deposition for all compounds, though HCB was closest to air-water equilibrium, though it is suggested that samples from around 75 degrees N in the Greenland Gyre represented a combination of surface and older/deeper Arctic water.

TL;DR: Air-water fugacity ratios (fa/fw) were calculated for fluoranthene and pyrene in remote open ocean areas suggesting air-water partitioning near equilibrium, andRatios for anthracene and phenanthrene were < 0.3 in the remote tropical Atlantic, suggesting net volatilization.

TL;DR: Air and seawater samples collected on board the RV Polarstern during a cruise from Bremerhaven, Germany to Cape Town, South Africa from October-November 2005 suggest that conditions are close to air-water equilibrium for most of the ocean, but net deposition is dominating over volatilization in parts of the transect.

TL;DR: This study highlights the occurrence of a prompt and complex response in the fate and distribution of POPs to dynamic biogeochemical control within the frame of the ecological succession, phytoplankton and zooplankon biomass dynamics produced bioaccumulation metrics varying over 1-2 orders of magnitude in the time frame of a few weeks and resulted in reduced trophic web exposure.

TL;DR: The need and benefit of developing PAS for POPs, the different approaches that can be used, and future developments and needs are explained are explained.
