Abstract

Abstract

In order to study the characteristics and sources of carbon components in PM_2.5 in Beijing and its surrounding areas in summer after the implementation of the Three-year Plan on Defending the Blue Sky and other policies, samples were collected at sites in Beijing urban area and Hebei suburban area in July 2019. The organic carbon(OC), elemental carbon(EC) and their components concentrations were determined using a thermo-optical carbon analyzer. The concentrations of secondary organic carbon(SOC) were also estimated by the OC/EC minimum ratio method and the minimum R squared method. The sources of carbon aerosols were analyzed by principal component analysis and back-trajectory analysis. The results showed that the average concentrations of OC and EC in PM_2.5 were(6.34±0.64) μg/m³ and(1.96±0.29) μg/m³ in Beijing urban area, accounting for 18.65% and 5.78% of PM_2.5, respectively. The average concentrations of OC and EC were(6.29±0.79) μg/m³ and(3.54±0.63) μg/m³ in Hebei suburban area, accounting for 17.69% and 9.53% of PM_2.5, respectively. The values of SOC in Beijing urban area were(3.35±0.59) μg/m³ and 3.98 μg/m³, respectively, accounting for(51.77±6.97)% and 68.48% of total OC concentration. The values of SOC in Hebei suburban area were(3.28±0.69) μg/m³ and 4.17 μg/m³, respectively, accounting for(62.42±9.62)% and 68.32% of total OC concentration. There was severe secondary pollution in Beijing urban area and Hebei suburban area in summer. Mixed vehicle emissions, road dust and combustion sources were the primary pollution sources of carbon aerosols in Beijing urban area. Industrial coal emission, vehicle exhaust and dust were the main pollution sources of carbon aerosols in Hebei suburban area. Back-trajectory analysis showed that the air mass trajectories in summer mainly came from southeast, southwest and south direction, which had a significant impact on carbon components of PM_2.5 in the urban area of Beijing and the suburban area of Hebei.
