| 英文摘要 | The concentrations and congener-specific profiles of polybrominated diphenyl ethers (PBDEs) were investigated in the atmosphere, soil and moss samples were collected from Ny-angstrom lesund, Svalbard in the Arctic and King Georgia Island (KGI), Fildes Peninsula in Antarctica, respectively. The congener profiles of PBDEs were symmetrical between gas and moss, as well as between particles and soil at Ny-angstrom lesund and KGI, respectively, similar to a mirror image. The proportions of highly brominated congeners (for example, BDE-99, -153 and -183) in the particle phase and soil were higher than those in the gas phase and moss, while tri- and tetra-BDEs possessed higher proportions in the gas phase and moss at both sites. The slopes of log-log linear correlations between the gas-particle partition coefficient (K-p) and sub-cooled liquid vapor pressures (p degrees(L)) of PBDEs were observed at both sites compared with the values in the urban areas. Moreover, the slopes of logK(p) vs. logp degrees(L) (-0.51 at Ny-angstrom lesund and -0.29 at KGI) were notably close to the slopes of log-log linear correlations between the di-mensionless soil-moss quotient (QSM) and p degrees(L) (-0.42 at Ny-angstrom lesund and -0.22 at KGI). Significant correlations between particle fraction (phi(particle)) and soil fraction (phi(soil)) at both sites indicated that the gas-particle partitioning of PBDEs is directly related to their distribution in moss and soil.
