Radiocarbon analysis is a widely-used tool for source apportionment of aerosol particles. One of the big challenges of this method, addressed in this work, is to isolate elemental carbon (EC) for 14C analysis. In the first part of the study, we valid

We measured the radiocarbon isotope signals in various fractions of carbonaceous aerosols sampled across four seasons (Oct 2013–Jul 2014) in three megacities of China, viz., Beijing, Shanghai, and Guangzhou. The contributions of fossil fuel (FF) an

To determine the causes of a severe haze episode in January 2013 in China, a source apportionment of different carbonaceous aerosols (CAs) was conducted in a megacity in central China (Wuhan, Hubei Province) by using the measurements of radiocarbon a

Fossil and Non-fossil Sources of Organic and Elemental Carbon Aerosols in Beijing, Shanghai and Guangzhou: Seasonal Variation of Carbon Source

Autor: Yinjun Chen, Zhineng Cheng, Di Liu, Gan Zhang, Guangcai Zhong, Yan-Lin Zhang, Pingqing Fu, Chongguo Tian, Jun Li, Sönke Szidat, Junwen Liu, Matthias Vonwiller

Fossil fuel (FF) combustion and biomass burning are the two most important contributors to the highly polluted air in China. Given that the large territorial area of China, it is interesting to know how these two emission sources exert influences on
