Table 2 showed that the slopes of relation between PM 2.5 and PM10 at non-roadside stations and roadside stations which ranged from 0.53 to 0.73. When compared the non-roadside stations with the roadside stations, we did not find distinct difference between the ratios. The results probably meant that sources of PM2.5 and PM10 from the roadside and non-roadside stations were common. The R2 of each station ranged from 0.46 to 0.87, regardless of station type. This may indicate that the number of common sources and emission characteristics at each station could be difference. The station with higher R2 may have lower numbers of common source but with more intensity of emission and shorter distance to the source. While the lower R2 probably represents the influence of the various common sources, some with less intensity or longer distance from monitoring station. Local meteorological factors also determine the correlation
