Characteristics of VOCs Pollution in the Atmosphere During Ozone Pollution in Taian

The field monitoring of atmospheric volatile organic compounds (VOCs) during ozone pollution at three observation sites in Taian High-tech Zone, Daiyue district and Taishan district was carried out. Combined with the monitoring data, the characteristics of atmospheric ozone and VOCs pollution of three observation sites were analyzed. The results showed that the ozone mass concentration ranged from 21 to 276 µg/m3, and the concentration of VOCs ranged from 31.63 to 36.35 ppbv. Characteristics of species ratio results showed that the concentration of ambient VOCs in Gaoxin districts was strongly influenced by motor vehicle emissions, coal combustion, oil/gas and gasoline volatilization. In addition, the concentration of VOCs of Daiyue districts mainly came from vehicle emissions, biomass combustion source and solvent evaporation, Taishan district VOCs in the atmosphere mainly came from vehicle emissions, liquefied oil/gas and gasoline evaporation. Finally, the control of VOCs emitted from vehicle emission, solvent volatilization and LPG should be strengthened to reduce the concentration of VOCs in Taian, further reducing the pollution process of ozone.
