Abstract

Abstract

As a typical industrial city in western China, Lanzhou is having significant ozone pollution situation in recent years, and volatile organic compounds (VOCs) play a key role in the generation of secondary pollutants such as O₃ and PM_2.5. To study the characteristics and sources of VOCs pollution in Lanzhou, this study selected the VOCs components monitoring data from the monitoring stations of Lanzhou University in downtown area and Xigu Refining and Chemical Industry Zone in the west, and conducted research and comparative analysis on VOCs pollution characteristics and sources of the two stations based on the PMF model. The results showed that the average annual value of VOCs in the central urban area was 32.24×10^-9, with the highest concentration in December and the lowest in July; the average annual value of VOCs in the Xigu Refining and Chemical Industry Zone was 70.86×10^-9, with the highest concentration in May and the lowest in August; alkanes, alkenes, and halogenated hydrocarbons were the main VOCs composition species in the two regions. The overall VOCs emission level of the Xigu Refining and Chemical Industrial Zone was higher than that of the downtown area, in which the concentration of halogenated hydrocarbons was 2.5 times higher than that of the central urban area, the concentration of olefins and aromatic hydrocarbon was more than 2 times higher, and the pollution level of alkynes was decreased. Overall, the trend of VOCs concentration changes in both areas was higher in winter and spring months, and lower in summer and autumn months. PMF source analysis results showed that vehicle exhaust gas source, oil and gas volatilization source, and organic solvents application source are the three main VOCs sources in the downtown area, while the industrial source was the most important VOCs source in Xigu Refining and Chemical Industrial Zone. Therefore, Lanzhou’s VOCs emission reduction control should be focused on reducing anthropogenic sources such as the petrochemical industry, motor vehicle exhaust, and solvent use.
