文摘 利用大气细颗粒物采样仪器(青岛崂应2050型)和黑碳仪(SootScanTM Model OT21),于2016年5月至2017年4月对贵阳市城区大气黑碳进行了连续采样和监测。结果表明,大气黑炭的浓度为1.17 ~ 12.77 μg /m~3,平均值为5.19±1.91 μg / m~3,季节变化特征呈现为冬季>秋季>春季≈夏季。大气黑碳气溶胶含量与大气细粒颗粒物PM_(2.5)质量浓度及钾离子含量呈显著正相关性,相关系数分别为R~2 = 0.64(P<0.01)和R~2 = 0.31(P<0.01) 。源解析结果显示,化石燃料(51.9%) 、生物质燃烧(32.4%)和餐饮油烟排放(15.7%)是大气黑碳气溶胶的主要来源。后向轨迹模型HYSPLIT显示,贵阳市全年大气污染气团主要来自我国境内,污染气团的来源与贵阳市大气主导风向有关。
其他语种文摘 Atmospheric fine particle in Guiyang City was collected with Laoying Model 2050 during May 2016 to April 2017 and measured for black carbon ( BC) using Aethalometer ( SootScanTM Model OT21). Results showed that concentrations of BC ranged from 1.17 to 12.77 μg /m~3,with an average of 5.19±1.91 μg /m~3. Seasonal variation of BC was in the order of winter > autumn > spring ≈ summer. Significantly positive correlations between BC and PM_(2.5) ( R~2 = 0.64,P < 0.01) as well as between potassium ion ( R~2 = 0.31,P < 0.01) were observed. Sources apportionment suggested BC originated from fossil fuels ( 51.9%),biomass burning dust ( 32.4%),and catering fume emissions ( 15.7%). Cluster analyses on back-trajectories illustrated that the impacted air mass mainly came from domestic regions,and was controlled by dominant wind directions in Guiyang.
