兰州大气细颗粒物中有机碳与元素碳的污染特征
|
Abstract:
摘要 采集兰州冬季采暖期及夏季PM2.5样品共60个,通过DRI 测定有机碳(OC)和元素碳(EC). 结果显示:冬季OC和EC平均质量浓度分别为(35.39±13.88)μg/m3和(13.80±5.41)μg/m3,夏季分别为(9.74±3.30)μg/m3和(4.44±2.00)μg/m3,冬季污染远高于夏季. 冬夏季OC和EC相关系数分别为0.91和0.76,表明冬季兰州PM2.5中OC和EC的来源相似. 二次有机碳质量浓度冬夏季分别为(8.48±6.10)μg/m3和(3.07±2.20)μg/m3,约占OC含量的(22.46±11.93)%和(31.29±18.51)%,表明兰州冬夏季PM2.5中OC的来源均以一次排放为主,夏季二次源贡献高于冬季. 对8种不同温度段碳质组分分析表明,兰州冬季生物质燃烧较夏季有所增加,夏季可能主要为机动车尾气.
