摘要
The marine aerosols were collected in the atmosphere over the Kuroshio area for 2 a from 1987 to1988. The ions of chlorine, magnisium, potassium, calcium, fluorine, sulfate, nitrate, water soluble and organicphosphorus, water and acid soluble manganese, iron, lead, copper, vanadium and cadmium were determined. Theresults show that the sources of species in the marine aerosol may be traced to sea water, land mineral dusts andcontinental air pollutants. The concentrations of continental source matter in the marine aerosol also have an obvious seasonal variation with greatest contents in the winter. The major components of the continental source aerosolsare sulfate and nitrate, and mineral matters are secondary. The sequence of water solubility of the heavy metal isCd>Mn>Pb>Cu>Fe>V. The air to sea fluxes of the matter in the marine aerosols are also discussed. A significant content of sulfate and nitrate, and a considerable content of mineral matter are deposited to the sea water fromthe air.
