  abstract     = {{In recent decades, there has been increasing awareness in the cultural heritage field around good air quality, which is important both for humans and objects. Volatile organic compounds (VOCs) represent an important, complex and diverse class of indoor air pollutants. Different VOCs are related to negative health effects and/or can induce or accelerate the degradation of cultural objects. This study consists of a non-targeted screening and quantification of VOCs in 20 museum-depot units in Ghent (Belgium). The depot is built via a box-in-box system with only internal recirculation without any supply of fresh air.
Weekly-average concentrations of the different depots are obtained by passive sampling, followed by TD-GC-MS analysis. However, to use passive sampling as a reliable sampling technique, compound and sampler-specific uptake rates (UTRs) are needed. Therefore, 7-days experimental UTRs were determined by a simultaneous passive and active sampling of VOCs in one of the depot-units. These measurements resulted in the determination of UTRs for 73 VOCs, making an essential contribution to the literature concerning passive sampling as nowadays commonly used theoretical UTRs may significantly deviate from the real environmental UTRs.
These experimental determined UTRs were applied to quantify the VOCs present in the 20 museum-depots. The highest TVOC concentration (n=61) is 3446µg/m³, with an average of 2206±710 µg/m³. Benzyl alcohol is the most abundant VOC which contributes on average to 65% of the TVOC concentration (max. concentration 2141 µg/m³). Benzaldehyde, the second most abundant compound, was measured up to a concentration of 449 µg/m³ and contributes on average to 12% of the TVOC concentration. Source identification was achieved by analysis of VOCs in the headspace of different building materials. The results indicate that the epoxy floor is the main source of different VOCs, including benzyl alcohol and benzaldehyde, but also a wide range of C3- and C4-benzenes.}},
