The Study a Relationship of Vehicle Volume with Total Suspended Particulate (TSP) and Particle Matter Less Than 2.5 Microns (PM2.5), Mueang District, Kamphaeng Phet Province

Abstract

The study a relationship of vehicle volume with total suspended particulate (TSP) and Particle matter less than 2.5 microns (PM2.5), Mueang District, Kamphaeng Phet Province The results found that the total TSP detected for all 7 days did not exceed the standard value (0.33 mg/cubic meter) in the range of 0.002 - 0.011 mg/m³ and the PM2.5 detected exceeded the amount of particulate matter smaller than 2.5 microns (PM2.5) exceeding the standard value (0.05 mg/m³) on days 2, 3, 4 and 5. May 2022, with a range of 0.014 -0.092 mg/m³. The relationship value of vehicle volume with the TSP and the PM2.5It found that vehicle relationship values and total dust content were highly correlated, and the relationship between the PM2.5 on vehicle volume and the TSP was moderately correlated, which is to say, if the vehicle volume increased, the amount of dust would increase.
