贵阳市大气黑碳污染特征
Pollution characteristics of atmospheric black carbon in Guiyang City, Southwest China
摘要
Abstract
By using URG Model 2000-01J and Aethalometer, the atmospheric black carbon concentration in Guiyang City was continuously detected from September to November, 2008. The 24 h atmospheric black carbon concentration during the detection period was 1.6-12 μg · m-3, with a mean value of 4. 1 μg · m-3 The 12 h atmospheric black carbon concentration was mainly in the range of 2-5 μg · m-3, its daytime variation range was 1.9-9.2 μg · m-3, with a mean value of 3.9 μg · m-3, and its nighttime variation range was 0.48-15 μg · m-3 , with a mean value of 4.3 μg · m-3. The atmospheric black carbon concentration had the same variation trend as atmospheric PM2.5 concentration, and there existed a positive correlation (r=0.84, P＜0. 0001, n= 178 ) between them. The variation trend of the atmospheric black carbon concentration was also affected by the relative humidity, temperature, and wind speed.关键词
