Atmospheric concentrations, occurrence and deposition of persistent organic pollutants (POPs) in a Mediterranean coastal site (Etang de Thau, France)

Abstract : Atmospheric concentrations and deposition fluxes of PCDD/F and PCB have been evaluated over a 1-year period in a Mediterranean coastal lagoon (Etang de Thau, France). Indicative PBDE air concentrations in the hot season are also reported in this work. P2,3,7,8-PCDD/Fs and P18PCBs (gasþ particulate) air concentrations ranged from 67 to 1700 fgm-3 and from 13 to 95 pgm-3, respectively whereasP8PBDEs (gas þ particulate) summer time levels varied from 158 to 230 pgm-3. The PCDD/F and PCB atmospheric occurrence over Thau lagoon and subsequent inputs to the surface waters are determined by an assemble of factors, being the seasonality of atmospheric concentration, the air mass origin and meteorological conditions important drivers. Total (wet þ dry) P2,3,7,8-PCDD/Fs and P18PCBs deposition fluxes to Thau Lagoon waters are 117 and 715 pgm-2 d-1, respectively
