“…However, while this study produced a range of source profiles for PM 10 , the number of profiles for PM 2.5 was relatively limited. In addition to source characterization, previous studies have used other approaches including use of diagnostic tools such as elemental ratios and enrichment factors to identify chemical source markers for PM sources (Artidsoglou and Samara, 2005;Han et al, 2006;Han et al, 2007;Tsai et al, 2007;Cao et al, 2008;Cheng et al, 2010;Kong et al, 2011;Cesari et al, 2012). The key objective of this study was to prepare PM 2.5 source profiles for resuspended dust and vehicular exhaust emission sources for Raipur (India), and a companion paper on other profile categories has recently been published (Matawle et al, 2014).…”

This paper describes results from a detailed source profile characterization study conducted in Raipur, India to prepare source profiles for traffic and dust-related sources. A companion paper has been published with results for a range of other combustion sources. PM 2.5 samples were analyzed for mass, elements (Al, As, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, S, Sb, Se, V, Zn), ions (Na + , K + , Mg 2+ , Ca 2+ , NH 4 + , Cl -, F -, NO 3 -, SO 4 2-) and carbonaceous fractions (OC and EC). All dust profiles were dominated by crustal elements (Al, Ca, Fe and Mg), while carbonaceous species (OC and EC) were most abundant in vehicular emission profiles. Trace element fraction was found to be significantly higher in vehicular exhaust compared to the resuspended dust. Remarkably, sulphur abundance was observed to be several-fold higher in vehicular emission profiles than resuspended dust profiles. Al and Ca were identified as reliable markers for resuspended dust while V, Pb and EC were identified as markers for vehicular exhaust.

“…The weight of the mobile monitoring system including the vehicle (Hyundai Terracan EX250) and all of the instrumentation is approximately 2 metric tons, which is about the same as the fleet average weight of vehicles in the Seoul metropolitan area. A detailed design of the mobile monitoring system was presented in a previously published work (Han et al, 2007).…”

“…This ensures a wide range of silt loading values, where the correlation equation can be applied with reasonable accuracy on paved roads in the Seoul metropolitan area. The detailed procedure for obtaining the correlation equation for silt loading measurement can be found in previously published works (Han et al, 2007;Kuhns et al, 2001 …”

This study is considered the first attempt to apply a mobile monitoring system to estimating silt loading on paved roads in a megacity such as the Seoul metropolitan area. Using a mobile monitoring system developed in 2005, we estimated silt loadings on representative paved roads in the Seoul metropolitan area, including the city of Incheon, over a period of 3 yr. The temporal and spatial characteristics of silt loading were investigated for the carefully selected roads that may reflect the characteristics of the cities of Seoul and Incheon. In this study, changes in the average silt loading values were investigated in terms of land use, the temporal resolution of data acquisition (i.e., seasonal, daily, three-hour scale), the road width or number of lanes, and rainfall, which may affect the characteristics of the average silt loading significantly. It was found that the advantages of using the mobile monitoring system are its ability to obtain a large quantity of silt loading data in a short period of time and over a wide area and its ability to create a silt loading map showing the relative magnitude of silt loading in relation to a specific location, which makes it possible to easily locate hot spots.Implications: This study may be considered the first practical application of a mobile monitoring system to obtain the silt loading data on paved roads in a mega-city such as Seoul. It was found that the advantages of using the mobile monitoring system are its ability to obtain a large quantity of silt loading data in a short period of time and over a wide area and its ability to create a silt loading map showing the relative magnitude of silt loading in relation to a specific location, which makes it possible to easily locate hot spots to be cleaned cost-effectively by city officials.

“…최근 본 연구팀에서는 서 울시 동대문구 청량리 교차로 도로변에서 입자상 및 가스상 대기오염물질을 측정하였으며, 측정한 대기오 염물질의 주간변화, 일변화 경향이 자동차 통행량과 밀접한 관련이 있음을 밝혀냈다 (Lee and Bae, 2010;Woo et al, 2008). 실제 주행 중 도로상 대기오염에 관한 연구로는 이동먼지측정시스템을 이용하여 포장도로 silt loading 값의 시간적, 공간적 분포의 측정 및 재비산 먼지의 발생 특성에 관한 연구가 진행되고 있다 (Han et al, 2007). 또한, 현행 자동차 배기가스 수시점검의 문제 점을 보완하기 위해 이동이 쉬우면서 오염물질 과다 배출 차량을 식별할 수 있는 원격측정장비 (remote sensing device, RSD)가 개발되어 가솔린 및 디젤 자 동차를 대상으로 CO, HC, NO의 배출농도를 측정하 였으며, 청정차량이나 유해가스 과다배출 차량을 식 별하는데 타당성이 있다고 보고되었다 Park et al, 2005 "±" indicates standard deviations.…”
