Sources, Solubility, and Deposition Fluxes of Trace Elements in Atmospheric Aerosols over the Yellow Sea
Atmospheric dry deposition is reported as one of important sources of trace elements in the Yellow sea. Besides particle loadings, solubility of trace elements in sea-water is an important parameter determined the bioavaiblity of these deposited elements. In this study, 36 total suspended particulate samples were collected over the Yellow Sea during four cruises during the period from February to August, 2009 and were used to investigate solubility of trace elements in sea-water. The solubility of these metals was Fe(4.2%±3.3%), Al(7.8%±12%), Ba(23%± 26%),Cd(48%±36%), Mn(50%±29%), P(56%±26%), Zn(53%±31%), Cu(58%±34%), Pb(75%±28%), respectively. The solubility of these elements was apparently affected by their corresponding sources and aging processes, e.g., the solubility of Fe in the aerosol from the continental source was 5-6% higher than that from oceanic source. Bio-available dry deposition fluxes are thereby estimated considering element s solubility in sea water
