摘要
于2004年至2005年采集厦门市3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+约占总质量浓度的40%,总碳TC占21%,Al、Si、Ca和Fe等地壳元素仅占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.
Atmospheric aerosol （PM10） samples were collected analyzed by XRF, IC and Carbon Analyzer. Concentrations of second highest in winter, and lowest in summer. Secondary i at Xiamen from December 2004 to July 2005, and aerosol species were commonly highest in sprihg, ons including SO^2- 4 , NO3^- and NH^＋ 4 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.
