2013年对韩国首尔龙山市中心城区PM2.5和PM10浓度进行了监测。PM2.5和PM10的日平均浓度分别为26.6 ± 12.6和45.0 ± 20.4 μg m−3。PM2.5浓度略高于韩国环境部（KMOE）设定的年度标准值（25 μg m−3），而PM10浓度略低于其指导值（50 μg m−3）。两种PM的月平均值（μg m−3）的比较显示，1月份的浓度最高（PM2.5：36.9和PM10：59.7），9月份的浓度最低（PM10：28.1）和10月份的浓度最低（PM2.5：14.9）。PM浓度与某些气态污染物（例如，CO、SO2和NOx）表明了贡献源过程的共性，如交通和工业排放。反轨迹（BT）分析的结果还表明，研究区域的PM污染可能受到许多来源的影响，如亚洲粉尘，火山排放和周边国家（中国，俄罗斯和日本）的工业活动。
The concentrations of PM2.5and PM10were monitored at a central urban area of Yongsan (YS), Seoul, Korea during 2013. The daily average concentrations of both PM2.5and PM10fractions, were 26.6 ± 12.6 and 45.0 ± 20.4 μg m−3, respectively. The observed PM2.5concentration slightly exceeded the annual standard value (25 μg m−3) set by the Korean Ministry of Environment (KMOE), while that of PM10was slightly lower than its guideline value (50 μg m−3). Comparison of the monthly mean values (μg m−3) of both PM fractions showed maximum concentrations in January (PM2.5: 36.9 and PM10: 59.7) and minimum concentrations in September (PM10: 28.1) and October (PM2.5: 14.9). The existence of strong correlations between the concentrations of PM and some gaseous pollutants (e.g., CO, SO2, and NOx) indicated the commonality of contributing source processes, such as traffic and industrial emissions. The results of a back-trajectory (BT) analysis also suggests that the PM pollution in the study area is likely to have been affected by many sources such as Asian dust, volcanic emissions, and industrial activities in the surrounding countries (China, Russia, and Japan).
