使用在线离子色谱分析了苏州市区春节期间 PM2．5中水溶性离子。结果表明：春节期间存在2个空气污染高峰时段（初一和初五），其中初一凌晨 PM2．5达到最高峰，小时质量浓度为571μg/m3；烟花爆竹集中燃放时段，PM2．5中 K ＋、Cl -、Mg2＋质量浓度明显上升，初一凌晨与腊月三十凌晨相比，K ＋、Cl -、Mg2＋质量浓度分别增加了117倍、80．7倍、18．0倍；相关性分析表明，PM2．5中 K ＋、Mg2＋、Na ＋、Ca2＋在烟花爆竹燃放时段可能具有相同的来源。
使用在線離子色譜分析瞭囌州市區春節期間 PM2．5中水溶性離子。結果錶明：春節期間存在2箇空氣汙染高峰時段（初一和初五），其中初一凌晨 PM2．5達到最高峰，小時質量濃度為571μg/m3；煙花爆竹集中燃放時段，PM2．5中 K ＋、Cl -、Mg2＋質量濃度明顯上升，初一凌晨與臘月三十凌晨相比，K ＋、Cl -、Mg2＋質量濃度分彆增加瞭117倍、80．7倍、18．0倍；相關性分析錶明，PM2．5中 K ＋、Mg2＋、Na ＋、Ca2＋在煙花爆竹燃放時段可能具有相同的來源。

The characteristics of the water-soluble ions in PM2.5 were analyzed by on-line ion chromatogra-phy during the Spring Festival (from February 9 to 15,2013)in Suzhou city.It indicated that there were two heavy air pollution periods during the Spring Festival.Peak value come in the early morning of the Lunar New Year's Day,with an hourly concentration of 571 μg/m3.During the timescales of concentrated setting off fire-crackers and fireworks,the concentration of potassium,chloride,magnesium ion in PM2.5 were increased signifi-cantly.Compared with the early morning of February 9,the concentration of potassium ion,chloride ion and magnesium ion in the early morning of the Lunar New year's Day increased 1 17 times,80.7 times,and 18.0 times,respectively.According to correlation analysis,during the timescales of concentrated setting off firecrack-ers and fireworks,the potassium ion,magnesium ion,sodium ion,calcium ion in PM2.5 may have the similar e-mission source.
