摘要
在大连海域采集44个气溶胶样品,利用离子色谱法及原子吸收分光光度法测定其中的SO2-4、NO-3、Cl-、Na+、Mg2+、NH+4、Al、Fe、Mn、V、Zn、Co、Cu、Pb、Cd。应用因子分析、回归分析及比值分析对气溶胶物质来源进行鉴别。结果表明,大连海域大气气溶胶物质主要来自海水、气态物(SO2、NOx)、土壤尘、煤烟尘、燃油灰和工业废料。
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.
