In this study, we simultaneously measured the PM10 and PM2.5 mass concentrations their heavy metal content for three days at a subway station in Seoul to investigate airborne PM flows. The average were 59 µg m–3, 37 111 369 m–3 43 28 58 132 outdoor air inlet, concourse, on platform, tunnel, respectively. We also found strong correlations between temporal variations adjacent sampling locations both fractions, although they higher PM2.5. Additionally, of trace metals detected inside (the...
Despite the prolonged global spread of COVID-19, few studies have investigated environmental influence on SARS-CoV-2 RNA with a metropolitan scale, particularly detection after disinfection at multi-use facilities. Between February 2020 and January 2021, 1,769 indoor air samples object surfaces were tested 231 facilities where confirmed cases known to occurred in Seoul, determine whether could be detected even disinfection. Samples collected by scanner swab pipette real-time RT-PCR. As...

Objectives: This study was conducted to evaluate the emission of VOCs from clothing that had been dry cleaned. Methods: In order ensure same conditions, f100% wool scarves were selected as fabric type. Four identical tests on option either removing plastic bags which came cleaning shop or not. The scarf located inside a closet room for one two days. Small chamber determine VOC characteristics under conditions such temperature, humidity, loading factor, and air exchange rates. Air sampled by...
This study investigated 180 students’ indoor environmental awareness of rest spaces and measured the outdoor concentrations PM10, TVOCs, HCHO in 8 from October 2019. 89.4% students responded that they use at least once a day most respondents are using university. The largest number to tight space as main cause air pollution spaces. 62.1% answered experienced health symptoms Among them, 32.5% said irritation eyes, neck, nose, 12.1% headaches. Indoor levels did not exceed quality...
When collecting air samples for analyzing the ionic components of fine dust, a (+) error may occur because gaseous precursors react with each other on filter surface to form particles. To remove NO2, SO2, HNO3, HNO2, and NH3, which cause these errors, denuder must be installed in front sampling port. However, extensive use sequential samplers that automatically replaces filters once every 24 h, denuders is decreasing. In this study, effect installation was analyzed by operating sampler...
