Exploration of the Variation Law of Road Dust Concentration in Minhang District,Shanghai City Based on Online Monitoring
Based on the monitoring data of 70 online monitoring points for road dust in Minhang district,Shanghai city from 2020 to 2022,correlation analysis is conducted on the concentration of inhalable particulate matter,meteorological parameters,environmental statistics,pollutant emissions from enterprises,and vehicle flow obtained from atmospheric micro stations in the same region during the contract period,and the application of online monitoring technology for road dust in atmospheric environmental quality monitoring is studied,and the changes in road dust concentration are analyzed to explore the patterns and main influencing factors of road dust changes.The results indicate that the online monitoring data of road dust has good scientificity and accuracy,and the dust concentration on roads in Minhang district,Shanghai city has been decreasing year by year,with higher levels in spring and winter,lower levels in summer and autumn,and higher levels during the day and lower levels at night.The changes in road dust concentration are closely related to factors such as traffic flow and meteorology,and are not related to the emissions of exhaust pollutants from environmental statistics enterprises.
