摘要
近年来可吸入颗粒物成为影响长沙市环境空气质量的首要污染因子,城区空气中可吸入颗粒物浓度时有超标。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、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 particulate matter （ PM2.5 ） concentrations in the air at Changsha Railway Station and Affiliated High School of Hunan Normal University were contin- uously monitored with environmental particle detector（TEOM1405 - DF）. Pollution characteristics and seasonal variation of the mass concentration of particulate matter were discussed. The local meteorological background, particulate pollution and back traj- ectory in typical haze weather were analyzed.
