Air freshener	947.27 ± 173.78	480.87 ± 213.52^d	325.39 ± 510.33^d	15.2 ± 5.2^d	33.3 ± 14.48^d	1.7 ± 4.86^d	4,808.9 ± 801.54^d

The samples were collected in vacuum sampler bags with Tedler bags (10L) connected to the exhaust port of the inhalation chamber. The vacuum sampler bag operated at ~3 mL/min. Volatile organic compounds emitted from the AF were analyzed using TDS-GC-MSD in NICEM of Seoul National University. Samples were collected eight times during individual experiments.

Table 1 represents VOCs that were frequently detected in AFs or were detected at high concentrations. In addition, 5VOCs such as toluene and xylene were detected in the AF.

TVOCs: Total VOCs, the list of all VOCs detected in the AF, is attached to the Excel file entitled ‘identification of AF ingredients.
