| 英文摘要 | Aromatic hydrocarbons are important anthropogenic precursors of tropospheric ozone and secondary organic aerosols. here we measured ambient aromatic hydrocarbons from march 2012 to february 2014 at six rural sites in china's developed coastal regions. on average, benzene (b) comprised >50% of total benzene (b), toluene (t), ethylbenzene (e), and xylenes (x) (btex) at sites in the northeast china plain (necp) or in the north china plain (ncp), whereas t, e, and x accounted for >77% of total btex at sites in the yangtze river delta (yrd) and the pearl river delta in the south. btex at the northern sites was significantly correlated (p < 0.01) with combustion tracer-carbon monoxide (co) but weakly correlated with traffic marker-methyl tert-butyl ether (mtbe), suggesting that their main sources were coal and biofuel/biomass burning with substantially elevated b levels during the winter heating period. in contrast, btex at the southern sites originated mainly from traffic-related and/or industrial emission sources, as indicated by the poor correlations with co but highly significant (p < 0.01) correlations with mtbe and tetrachloroethylene, an industrial emission tracer. the b/co emission ratios from measurement agreed within a factor of 2 with that of a previous widely used emission inventory of china, but the t/co ratio at the necp site and the o-x/co ratio at the ncp site were 29% and 38% of that in the inventory, respectively; the e/co and x/co ratios at the yrd site were 3.2-3.5 fold that in the emission inventory. |
