AbstractIn terms of understanding Fe mobilization from aerosol particles in East China, the PM2.5 particles were collected in spring at Shanghai. Combined with the backtrajectory analysis, the PM2.5/PM10 and Ca/Al ratios, a serious duststorm episode (DSE) during the sampling was identified. The single-particle analysis showed that the major ironbearing class is the aluminosilicate dust during DSE, while the Fe-bearing aerosols are dominated by coal fly ash, followed by a minority of iron oxides during the non-dust storm days (NDS). Chemical analyses of samples showed that the fractional Fe solubility (%Fe-s) is much higher during NDS than that during DSE, and a strong inverse relationship of R-2 = 0.967 between %Fe-s and total atmospheric iron loading were found, suggested that total Fe (Fe-T is not controlling soluble Fe (Fe-s) during the sampling. Furthermore, no relationship between Fes and any of acidic species was established, suggesting that acidic process on aerosol surfaces are not involved in the trend of iron solubility. It was thus proposed that the source-dependent composition of aerosol particles is a primary determinant for %Fe-s. Specially, the Al/Fe ratio is poorly correlated (R-2 = 0.113) with %Fe-s, while the apparent relationship between %Fe-s and the calculated K-BB(+)/Fe ratio (R-2 = 0.888) and the V/Fe ratio (R-2 = 0.736) were observed, reflecting that %Fe-s could be controlled by both biomass burning and oil ash from ship emission, rather than mineral particles and coal fly ash, although the latter two are the main contributors to the atmospheric Fe loading during the sampling. Such information can be useful improving our understanding on iron solubility on East China, which may further correlate with iron bioavailability to the ocean, as well as human health effects associated with exposure to fine Fe-rich particles in densely populated metropolis in China.
