Measurement of near-road PM10 and PM2.5 in Manila City roads
The mass concentration and size distribution of PM10 and PM2.5 were determined in this study. The highest PM10 and PM2.5 concentrations were recorded at Taft Avenue. On the other hand, size distribution of PM in the sampling sites showed that Roxas Boulevard had the highest number of PM2.5 particles. All the sampling sites had a high vehicular density which can account for their high PM mass concentration and size distribution. Some effects of meteorological parameters on mass concentration were also observed.
