Scientific analyses were carried out to determine the effect of ozone formation based on volatile organic compounds (VOCs) at the central area of Seoul from October 17 to November 11 in 2021 during Satellite Integrated Joint monitoring of Air Quality (SIJAQ 2021) campaign. VOCs including formaldehyde (HCHO) can be emitted by biogenic, primary emission, and secondary formation in urban areas. In this study, HCHO were collected using a 4-hr integrated sequence sampler equipped absorption tubes including 2,4-dinitrophenylhydrazine (DNPH). Liquid Chromatography/Quadruple Time Of Flight (LC/QTOF) was utilized to determine the quantitative analysis of HCHO. As a result, overall average of HCHO is presented as 7.4 ppb, which is about 2.4 times higher than toluene concentrations. Strong diurnal pattern as in day-time maximum indicates that secondary HCHO is dominant. A quarter of measured ozone could be originated from HCHO from ozone formation potential model. The current result can be applied to reduction strategies for ozone and verification of satellite HCHO monitoring.

Despite the importance of air pollution emissions in port areas, traditional air quality monitoring has mainly been carried out in populated areas or industrial complexes. However, air pollutants emitted in port areas also make an important contribution to local air quality. Therefore, the particle number concentrations and NO 2 concentrations were measured using the optical particle counter (OPC) and the gas detector during the air quality intensive observation period from October 11 to November 1, 2018 at Gangneung Port (37.76°N, 128.954°E). The averaged particle number concentrations increased mainly under land breeze conditions rather than sea breeze wind, and the contribution of pollutants originated from the surrounding area was greater than that from the coastal ocean. The hourly change in NO 2 concentrations showed a relatively high correlation with air temperature and ship operation frequency. Diurnal change of NO 2 concentration also followed the photochemical reaction cycle according to the change of insolation. Overall, the particle number concentrations and NO 2 concentrations measured at Gangneung Port were largely influenced by the local emissions and weather system. Additional research will be able to provide information on air quality changes and impacts in the port area.
