(SO4� ) aerosols were 1.2 ± 0.8 mgC m � 3 , 4.2 ± 1.6 mgC m � 3 , 1.3 ± 1.0 mgC m � 3 , and 4.0 ± 3.4 m gm � 3 , respectively. Almost all species concentrations were highest in Chinese air masses, while they were lowest in marine air masses. The observed DBC/DCO slope of 9.7 ng m � 3 ppbv � 1 in Chinese outflow agrees reasonably with the estimates of the BC/CO emission ratios over northeastern China. The transport efficiencies of SOx (SO2 +S O4� ) are calculated to be 40–45% from the observed SOx-CO correlation. The relationships of the SO4� /BC and WSOC/BC ratios with transport time from the continent suggest that a majority of SO4� and WSOC aerosols were formed by about
