RESUMO
From 2006 to 2007, four surveys for marine atmosphere in East China Sea were carried out included different seasons (spring, summer, autumn and winter). Based on the survey data of heavy metals in marine atmospheric particles, analyzed the source of heavy metals by the calculation of Enrichment Factors, calculated the air-sea fluxes via dry deposition. The results showed, comparing with the crustal and seawater, the heavy metals including Cu, Pb, Cd and Zn were highly concentrated, mainly from the pollutants of human activities. The fluxes of heavy metals via dry deposition were Zn [10.92 mg/(m2 x a)] > Pb [2.299 mg/(m2 x a)] > Cu [1.611 mg/(m2 x a)] > Cd [0.017 mg/(m2 x a)]. The fluxes of heavy metals in winter were highest,the summer and autumn were lower. The input of Cu, Pb, Zn and Cd from atmosphere to sea via dry deposition was 2 376 t, nearly 13% compared with the input of The Changjiang River (Yangtze River).
