| Abstract: | Forty four marine aerosol samples were collected in the atmosphere over near seashore in Dalian Shicao marine atmospheric protection station from May 1994 to November 1995.IC and AAS were used to determine SO 2- 4,NO - 3,Cl -,NH + 4,Na +,Mg 2+ ,Al,Fe,Mn,V,Zn,Co,Cu,Pb,Cd.Sources of marine aerosol could be discriminated by using methods of factor analysis, regression analysis and ratio analysis.Atmospheric marine aerosol was derived from seawater,gaseous substance,soil dust,ash fly from burning coal,ash fly from burning fuel and industrial waste at DaLian sea area. |
