    Understanding Ozone Formation and Carbonyl Contributions in the Seoul Metropolitan Area by Seung-Ha Lee, Ji-Seon Lee, Hyung-Min Lee, Hyeong-Ahn Kwon, Caroline R. Nowlan, Gonzalo González Abad, Rokjin J. Park, Ji-Hoon Park, Soyoung Kang, Hye-Jung Shin, Dai-Gon Kim, Jung-Min Park

    Published 2023-11-01
    “…We revisited the ozone formation condition and investigated the contribution of each component using observations of routinely measured volatile organic compounds (VOCs) and, for the first time, employed multiyear ground observations of carbonyl compounds (formaldehyde, acetone, and acetaldehyde) from the two sites in Seoul Metropolitan Area (SMA), Seoul and Incheon, during the 2016–2018 ozone season (May–September). …”

    Field Tests of Indoor Air Cleaners for Removal of PM2.5 and PM10 in Elementary School Classrooms in Seoul, Korea by Bangwoo Han, Keejung Hong, Dongho Shin, Hak-Joon Kim, Yong-Jin Kim, Sang Bok Kim, Sangwoo Kim, Cheong-Ha Hwang, Kwang-Chul Noh

    Published 2022-03-01
    “…Eight models of air cleaners with clean air delivery rates ranging from 9.9 to 21.3 m3 min-1 were tested in the classrooms of two elementary schools in Seoul. Average PM2.5 and PM10 levels were 7.3 ± 0.7 and 45.5 ± 4.1 µg m-3 in classrooms equipped with one air cleaner and 4.2 ± 0.6 and 24.6 ± 2.5 µg m-3 in classrooms with two air cleaners, whereas they were 22.1 ± 2.6 and 109.1 ± 9.6 µg m-3 in classrooms with no air cleaner and 36.9 ± 5.1 and 74.1 ± 10.6 µg m-3 outdoors, respectively. …”

    Characterization of Seasonal Difference of HULIS-C Sources from Water Soluble PM2.5 in Seoul, Korea: Probing Secondary Processes by Hyung-Min Lee, Se Pyo Lee, Yugen Li, Jian Zhen Yu, Jin Young Kim, Yong Pyo Kim, Ji Yi Lee

    Published 2020-10-01
    “…The HULIS-C in Seoul had an annual average of 2.0 µg m−3, and displayed a seasonality of highest abundance in the winter (2.7 ± 1.3 µg m−3) and the lowest in the summer (1.7 ± 0.8 µg m−3). …”

    Source Quantification of PM10 and PM2.5 Using Iron Tracer Mass Balance in a Seoul Subway Station, South Korea by Jihwan Son, Kwangrae Kim, Seungmi Kwon, Seung-Myung Park, Kwangtae Ha, Yunmi Shin, Mijin Ahn, Seogju Cho, Jinho Shin, Yongseung Shin, Gangwoong Lee

    Published 2021-03-01
    “…Abstract In this study, we simultaneously measured the PM10 and PM2.5 mass concentrations and their heavy metal content for three days at a subway station in Seoul to investigate the airborne PM flows. The average concentrations were 59 µg m−3, 37 µg m−3, 111 µg m−3, and 369 µg m−3 for the PM10 and 43 µg m−3, 28 µg m−3, 58 µg m−3, and 132 µg m−3 for the PM2.5 at the outdoor air inlet, in the concourse, on the platform, and in the tunnel, respectively. …”
