[HTML][HTML] Characterization of fine particulate black carbon in Guangzhou, a megacity of South China
Continuous measurement of fine particulate black carbon (BC) was conducted at an urban
site of Guangzhou in South China from December 2007 to December 2008. The daily
average BC concentrations ranged from 0.6 to 20.5 μg m− 3, with an average value of 4.7 μg
m− 3, which was substantially higher than those observed in the urban areas of other
developed countries. Diurnal fluctuations of BC were marked with two peaks, one in the
morning rush hour (08: 00 LT) and the other in the late evening hour (21: 00–22: 00 LT) …
