Minor effect of physical size sorting on iron solubility of transported mineral dust [PDF]

, 2011
Observations show that the fractional solubility of Fe (FS-Fe, ratio of dissolved to total Fe) in dust aerosol increases dramatically from ~0.1% in regions of high dust mass concentration to 80% in remote regions where concentrations are low.
