| 摘 要： | 对2015年3月—2016年2月邯郸市大气中的PM_(10)、PM_(2.5)和PM_(1.0)进行了在线监测,探讨了其质量浓度的变化特征,并分析了其质量浓度与风速、风向的关系。结果表明:邯郸市颗粒物质量浓度水平较高,β射线吸收法所监测的PM_(10_WET)、PM_(2.5_WET)和PM_(1.0_WET)年均浓度值分别为202.5,114.8,81.1μg/m~3,PM_(2.5_DRY)/PM_(10_WET)和PM_(2.5_WET)/PM_(10_WET)分别为0.58、0.70,PM_(1_DRY)/PM_(2.5_WET)和PM_(1_WET)/PM_(2.5_WET)分别为0.58、0.71,PM_(2.5)为PM_(10)中的主要组成,PM_(1.0)为PM_(2.5)中的主要组成。邯郸市PM_(10)、PM_(2.5)和PM_(1.0)质量浓度冬季最高;PM_(10)、PM_(2.5)和PM_(1.0)日变化峰值为上午09:00左右,谷值为下午16:00左右,扬沙、降雨,霾和春节不同条件下PM_(10)、PM_(2.5)和PM_(1.0)差异明显。邯郸市PM_(10)、PM_(2.5)和PM_(1.0)的浓度高值主要分布在风向0°~100°和175°~225°、风速小于1 m/s的情况下。

| Abstract: | This study monitored the online concentrations of PM 10,PM2.5 and PM1.0 in Handan during March 2015 to February 2016,discussed the varied characteristics of mass concentration,and analyzed the relationship of mass concentration with wind speed and wind direction.The result showed that the concentration of particles had a higher level,the annual concentration of PM10_WET,PM2.5_WET and PM1.0_WET monitored by β-ray-absorption method were 202.5,114.8,81.1μg/m3,PM2.5_DRY/PM10_WET and PM2.5_WET/PM10_WET were 0.58 and 0.70,PM1_DRY/PM2.5_WET and PM1_WET/PM2.5_WET were 0.58 and 0.71.PM2.5 was the major composition of PM10,and PM1.0 was the major composition of PM2.5.The mass concentration of PM1.0,PM2.5 and PM1.0 in Handan was highest in winter.The peaks and the valleys of PM10,PM2.5 and PM1.0 were about 9:00 a.m.and 16:00 p.m.,respectively.PM10,PM2.5 and PM1.0 were obviously different under several conditions:blowing sand,rain,haze and the Spring Festival.The high concentration of PM10,PM2.5 and PM1.0 mainly accumulated when the wind direction was 0° ～ 100°and 175° ～225°,and the wind speed was less than 1 m/s. |
