“…EC1 comes from automobile exhaust, and EC2 and EC3 come from diesel vehicle emissions. The emission sources of carbon fractions can be determined according to the distribution characteristics of each carbon component [54][55][56]. As mentioned in Section 3.2.2, the percentages of carbon fractions in the dust of residential areas in Nanchang City show a consistent sequence: OC3 > EC1 > EC2&OC2&OC4 > EC3&OC1, indicating that the sources of carbon fractions in the dust from Nanchang are basically stable, which roughly reflects that major sources include anthropogenic sources and motor vehicle emissions, the contribution of exhaust emissions from gasoline vehicles is higher than that of diesel vehicles, followed by coal-fired emissions, and the contribution of biomass combustion is low.…”

Regional air quality and major sources can be reflected by dust. 87 dust samples in Nanchang (four residential areas and three roadside points) were collected, with particle size and carbon components determined to discuss the distribution characteristics and the sources. The distribution of dust particle size in different sampling areas was similar, composed mainly of particles larger than 10 μm (over 69.8%). Dust particle size showed a decreasing trend with increasing horizontal distance from the main road and vertical height from the ground. EC in road dust was higher than that in residential dust. EC outdoors was higher than EC indoors in the same area. OC in indoor dust was higher than that in atmospheric dust when there were obvious indoor OC emission sources. The main carbon fractions in residential dust were OC3 and EC1, and in road dust were EC2 and OC3. The distribution of carbon fractions showed that OC3 and EC2 were mainly affected by human activities and motor vehicle emissions, respectively. The ratio of OC/EC and SOC in dust decreased from autumn to winter. SOC in the dust of Nanchang was at a medium level compared to other cities/regions around world. Clustering analysis and principal component analysis indicated that combustion sources (coal and biomass combustion, etc.), motor vehicle exhaust sources (gasoline and diesel vehicles), and human sources (cooking fumes, cigarette smoking, etc.) were the main contributors to the carbon components in dust.
