(BC) black carbon aerosol, with a particle size of about 0.01–1 μm, results from the incomplete combustion of fossil fuels, wood, and other biomass. The main sources of BC include industrial coal, automobile exhaust, kitchen smoke, burning forests, and crops. Zhang and Wang (2011) summarized the published research regarding BC and reported that it was a strong absorber of solar and infrared radiation, which can heat the atmosphere. It can also affect cloud formation and reduce snow albedo (Zhang and Wang, 2011, Zhang et al., 2012a, Wang et al., 2011). BC can absorb toxic substances and have an impact on human health when inhaled. In practice, combustion is rarely complete due to technological constraints, and together with BC, CO, (VOCs) volatile organic compounds, and non-volatile organic compounds and (OC) organic carbon aerosol besides CO2, can also be released into atmosphere simultaneously. Of which, BC has tightly relationship with OC. However, unlike BC, OC in the atmosphere has a strong cooling effect, and therefore the mixing ratio of the two forms of carbon from different emission sources is important to understand.
