Research on the Distribution Law of VOCs in Yangpu District From 2019 to 2023
Volatile organic compounds(VOCs)are precursors of PM2.5 and ozone.By controlling VOCs,the syner-gistic control of PM2.5 and ozone can be strengthened.This paper summarizes and analyzes the VOCs 36 monito-ring data of two existing VOCs stations in Yangpu district over the past three years.At the same time,combined with VOCs navigation data,it analyzes the composition pattern of VOCs in Yangpu District in recent years.① The proportion of alkanes in fixed stations is the highest,and the proportion is increasing year by year.② The navigation results show that road VOCs are mainly affected by the volatilization of oil,with the main proportion of substances being oxygen-containing and nitrogen-containing hydrocarbons(26％),halogenated hydrocarbons(22％),and alkanes(21％).③ The VOCs problem in Yangpu district is influenced by both internal and external factors,with local sources mainly including road traffic,emissions from 4S store maintenance,and emissions from enterprise production.The external source is the emissions from Gaoqiao Petrochemical in Pudong New Area dur-ing the summer.
