Abstract


Objective: The purpose of this study was to evaluate the indoor to outdoor ratio (I/O ratio) of time activity patterns affecting PM2.5 concentrations in homes in Korea through a simulation.

Methods: The time activity patterns of homemakers were analyzed based on the ‘Time-Use Survey’ data of the National Statistical Office in 2014. From September 30 to October 2, 2019, the experimenter lived in multi?family housing located in Guro-gu, Seoul. The I/O ratio of PM2.5 concentration was measured by installing sensor-based instruments.

Results: The average indoor and outdoor PM2.5 concentrations during the three days were 33.1±48.9 and 45.9±25.3 μg/m3 , respectively. The average I/O ratio was 0.75±0.60. The indoor concentration tended to increase when PM2.5 source activity such cooking and cleaning was present and outdoor PM2.5 was supplied through ventilation.

Conclusions: This study could be used as basic data for estimating indoor PM2.5 concentrations with personal activity pattern and weather conditions using outdoor concentrations.
