초록

To characterize atmospheric particles in Cheonan area, 5 monitoring sites representing highway area, commercialarea, residential area, and industrial areas were selected, and the mass concentrations of PM10 and PM2.5 weremonitored for 14 days at each site during 2007. The daily average PM10 and PM2.5 concentrations were in therange from 18.5 to 140.9g/m³ and 8.2 to 116.6g/m³, respectively, showing the highest mean concentrations atthe commercial area site and the lowest concentration at the residential area site. The daily average PM10 concen-trations at Shinan (Commercial area) and Bakseok (Industrial area) sites were exceeded the current NationalStandard for 1 and 2 days during the monitoring periods. The fractions of PM2.5 in PM10 were above 70% for allsites, indicating ne particles are the major constituent of atmospheric particles in Cheonan. The results indicatethat PM10 concentrations in Cheonan are at the concerning level, and the control strategy for fine particles isnecessary to address this issue.
