Popis Air-sea exchange of POPs and PAHs was assessed in Concepci acute accent on Bay during January, summer 2015. Results showed low levels, in air and water, for POPs (1-20 pg m(- 3), and 6-50 pg L-1, respectively) and for sigma PAHs (1-2 ng m(- 3) and 1-2 ng L-1, respectively). The highest levels were found for PBDEs (200-20,000 pg L-1) in the water samples (3-fold times higher than PCBs and OCP) and PBDE209 accounted for 90% of total sigma PBDEs.& nbsp;Air-sea exchange fluxes (ng m(- 2) d(-1)) were low in general, with exception of PBDEs showing values up to 40,000 ng m(-2) d(-1). Net deposition was found for PAHs, HCB and some PBDEs; while, BDE99, and BDE100 showed net volatilization. These findings contribute with new data of diffusive air-sea exchange on the southern hemisphere Pacific coast.
