摘要
采用环境颗粒物监测仪(TEOM1405-DF)分别观测了2010年1月～2013年1月长沙市火车站、湖南师范大学附属中学(简称:师大附中)的可吸入颗粒物(PM10)和细颗粒物(PM2.5)样品,初步探讨了长沙市颗粒物质量浓度的污染特征及其季节变化规律.结合气象背景资料对典型灰霾天气期间颗粒物污染情况和后向气流轨迹进行了分析.
From January 2010 to January 2013, the inhalable particulate matter {PM10 ） and the fine par- ticulate matter （PMz.s） concentrations in the air at Changsha Train Station and Affiliated High School of Hunan Normal University were continuously monitored with Environmental particle detector {TEOM1405- DF）. Pollution characteristics and seasonal variation of the mass concentration of particulate matter were discussed. Combining the local meteorological background, particulate pollution and back trajectory in typi- cal haze weather were analyzed.
