| 英文摘要 | pcdd/fs in the urban air of dalian, china were monitored with high-volume active sampler from november 2009 to october 2010. the concentration of cl4-8dd/fs ranged from 3065 to 49538 fg m(-3), with an average of 10249 fg m(-3). the international toxic equivalents (i-teq) value of that was 61.8-1182 fg m(-3), with an average of 235 fg m(-3), which was comparable to those in the other urban locations around the world. it was found that the cl4-8dd/fs appeared to be present mainly in the particle phase during winter, spring and autumn, while during summer which were dominantly in gas phase. the ratio of cl4-8dd/fs present in particle phase increased with the increasing level of chlorination. the concentrations of pcdfs and pcdds decreased with the increase of chlorinated level, while the concentrations of 2,3,7,8-pcdds congeners increased with the increase of chlorination level. the homolog profiles of the concentrations of pcdfs presented were higher than those of the pcdds, which indicated the pcdd/fs pollution source of the air in dalian was characteristic for thermal source pollution. the correlation analysis of meteorological parameters with the concentrations of cl4-8cdd/fs was conducted using spss packages, and it was found that the ambient temperature and atmospheric pressure were important factors influence the concentration of pcdd/fs in the air. the respiratory risk and intake dioxins of the residents around the sampling sites were studied in the paper. it was found that junge-pankow model was much more accurate in predicting the gas-particle partitioning behavior of pcdd/fs homologues during winter, while the harner-bidleman model shows better agreement with the measured data during winter and summer. |
