| 摘 要： | 于2004年～2005年采集厦门市三个代表性季节大气气溶胶PM10样品，利用X-射线荧光光谱、离子色谱、热光碳分析仪分析其主要化学成分。结果表明: 气溶胶的化学成分浓度呈现春季最高、冬季次之，夏季最低的季节变化特征。其中，二次离子SO42-、NO3- 与NH4+ 占到近40%；总碳TC浓度占21%；Al、Si 、Ca和Fe等地壳元素仅占总质量浓度的13%；海盐离子占7%，二次离子污染是影响厦门环境空气质量的主要因子。

| Abstract: | Atmospheric aerosol (PM10) samples were collected at Xiamen from December 2004 to July 2005, and analyzed by XRF、IC and Carbon Analyzer . Concentrations of aerosol species were commonly highest in spring, second highest in winter, and lowest in summer. Secondary ions including SO42-、NO3-, and NH4+ accounted for about 40% of PM10, and total carbon, crustal elements such as Al、Si、Ca and Fe , salt ions accounted for about 21%, 13%,, and 7%, respectively, of the PM2.5 mass. Secondary ion pollution is the major contributor to Xiamen air quality. |
