| 摘 要： | 为了解可吸入颗粒物污染水平与气象因素之间的关系,从2008年9月—2010年2月采集乌鲁木齐市可吸入颗粒物样品,并对其随时间的变化特征及其与气象因素之间的相关性进行了统计分析。结果表明,采样时间内可吸入颗粒物中PM2.5和PM2.5-10的质量浓度的范围分别为38.2~468.7μg/m3和20.8~243.1μg/m3,平均浓度分别为134.2μg/m3和69.2μg/m3。可吸入颗粒物同时受几种气象因素的影响,其浓度与温度、能见度、风速呈负相关,与湿度呈正相关。

| Abstract: | The variation trends of inlualable particles concentrations in Urumqi as well as the correlation of inhalable particles concentrations and meteorological factors during the sampling period were analyzed. The results showed as follows： the mass concentration of PM2.5 and PM2.5-10 was ranged from 38.2 μg/m3 to 468.7 μg/m3 and 20.8 μg/m3 to 243.1 μg/m3 respectively, average of 134.2 μg/m3 , 69.2 μg/m3 ; inhalable particles concentrations were influenced by several meteorological factors. It had negative correlation with temperature, wind speed and visibility and had positive correlation with relative humidity. |
