Polybrominated Diphenyl Ether Dynamics in Ambient Air and Atmospheric Bulk/Wet Deposition in Downtown Paris (France)

Résumé

This study reports on the polybrominated diphenyl ether (PBDE) atmospheric dynamics in the dense urban environment of downtown Paris (France). Eight PBDE congeners (BDE-28, BDE-47, BDE-100, BDE-99, BDE-154, BDE-153, BDE-183 and BDE-209) were simultaneously analysed in bulk and wet atmospheric deposition, as well as in ambient air (gaseous/particulate phases), twice a month over a 12-month period (May 2008-May 2009). The total air concentration of I pound 8PBDEs ranged between 12 and 185 pg m(-3), and the seasonal variations of PBDE levels were controlled by air temperature (except for BDE-209). Regarding bulk deposition, I pound 8PBDE flux was in the range 5-94 ng m(-2) day(-1), and it was positively correlated with atmospheric particulate phase PBDE concentrations. Meanwhile, the measured wet deposition flux of I pound 8PBDE ranged between 2 and 24 ng m(-2) day(-1), and its median contribution to bulk deposition was 39% only, which highlights the importance of dry deposition.
