Study on pollution characteristics of aerosols during sand-dust storm weather in Beijing

摘要：采集并分析了北京市2次沙尘暴天气和非沙尘暴天气TSP(总悬浮颗粒物,<100μm)、PM10(可吸入颗粒物,<10μm)的质量浓度、离子浓度、元素浓度等.研究结果表明,发生沙尘暴时大气气溶胶的污染水平极高,这种情况在北京市只有发生沙尘暴时才可能出现;地表扬尘对大气气溶胶的贡献显著,显示出沙尘暴时的污染特征.

Abstract：In the spring of 2000,there were 12 sand-dust storms that brought enormous impacts to atmospheric environment and daily life in Beijing.2 sand-dust storms were experienced in this study.Mass concentrations,ionic concentrations,elementary concentrations and etc of TSP(total supspended particulate,<100μm)and PM 10(inhalable particulate,<10μm)were sampled and analyzed.Results showed that pollution level of aerosols was extremely high and such kind of serious pollution only occurred during sand-dust storms.Contribution of ground dust to aerosols was very significant,which might be the pollution characteristics of sand-dust storm in Beijing.
