Study of Traffic-Related Urban PM Pollution at Different Locations

Abstract

The overall purpose of this study was to determine the ratio of PM2.5 in PM10. Measurements of suspended particulate matter were continuous and carried out at four sampling points in Veszprém with two high volume samplers. The primary point of view in choosing the site of samplings was the investigation of the effect of the road traffic on the PM2.5 and PM10 concentrations. Results show that the PM2.5/PM10 mass fraction mainly depends on the effect of vehicular traffic. Furthermore it was also found that the daytime concentrations differ from the overnight ones. Taking the PM2.5/PM10 ratios and calculating the PM2.5 concentrations from the PM10 data measured by the Hungarian Air Quality Network it can be concluded that many steps must be taken by the local governments in Hungary to fulfil the limits and target values for PM2.5 laid down in the directive 2008/50/EC of the European Parliament.
