Abstract
The air quality inside airport terminal buildings is a lesser studied area compared to ambient air quality at the airport. The contribution of outdoor particulate matter (PM), aircraft traffic, and passenger traffic to indoor PM concentration is not well understood. Using the largest airport in Southeast Asia as the study site (extends 17.9 square kilometers), the objective of this paper is to conduct a preliminary analysis to examine the mass concentrations of fine particles, including PM1 and PM2.5, and coarse particles PM2.5–10 inside a four-story terminal building spanning 400,000 square meters in Jakarta, Indonesia. The results showed the indoor/outdoor (I/O) ratio of 0.42 for PM1 with 15-min time lag and 0.33 for PM2.5 with 30-min time lag. The aircraft traffic appeared to have a significant impact on indoor PM1 and PM2.5, whereas the passenger traffic showed an influence on indoor PM2.5–10.
Highlights
The modern airport is a complex system with various types of facilities
Typical air quality parameters include total volatile organic compounds (TVOC), ultrafine particles (UFP), fine particles (FP) or PM2.5, and PM10
The hypothesis tests showed that the indoor PM2.5 and PM2.5–10 were significantly lower than those outdoors, whereas the PM1 concentration was comparable to the outdoor one
Summary
The modern airport is a complex system with various types of facilities. Some components of the airport include air traffic control facilities, airfield including approach zones, a terminal complex, a utility communications network, supporting and service facilities, and ground access system [1].Among them, the terminal buildings are unique in that they usually operate on a 24-h basis throughout the year and directly interact with majority of the passengers and airport employees.In recent years, the importance of air quality assessment at the airport has gradually been acknowledged.

The importance of air quality assessment at the airport has gradually been acknowledged. A number of studies on air quality have been conducted in various facilities at airports around the world. Lee et al [5] and Kungskulniti et al [6] used PM2.5 as a parameter to assess indoor air quality in airport smoking rooms. More studies can be found on ambient air quality at or near the airport. Hsu et al [7,8] monitored the UFP level near runways at two
