摘要: This study investigates the atmospheric occurrence of persistent organic pollutants (POPs) over Pacific Ocean near southern Taiwan and northern Philippines. We determined sixty-six compounds, including polychlorinated dibenzo-p-dioxins dibenzofurans (PCDD/Fs), dioxin-like biphenyls (DLPCBs), polybrominated diphenyl ethers (PBDEs), as well (PCDEs), (PBDD/Fs), (PBBs), in air samples simultaneously collected from offshore oceanic atmosphere (n=6) a rural area (n=2). calculated World Health Organization 2005 toxic equivalency levels (WHO2005-TEQ), for total POPs, PCDD/Fs, DLPCBs, PBDD/Fs, being 0.00612 pg WHO2005-TEQ/m(3) 0.0138 ocean land, respectively. found unexpected lower averaged PBDE concentrations (15.9 pg/m(3)) than (31.1 due to higher BDE209 congener, although difference was not statistically significant. have compared reported our field results with previously published datasets global oceans, which suggest PCBs PBDEs are dominant chemical contaminants among these halogenated POPs (e.g. Σdi-hepta could be range 0.09-48.7 8.07-94.0 pg/m(3), respectively, dataset). However, there still very few investigations on PCDEs PBBs data sums earlier studies. Finally, we point out that originated or continental East Asia easily reach remote sites via transport.
