“…Even Art Galleries showed a higher contribution of aldehydes in the presence of visitors (presence of visitors: PG 30.8 ± 18.0 µg/m 3 —SMM 25.6 ± 7.3 µg/m 3 —empty museum: PG 14.9 ± 6.30 µg/m 3 —SMM 18.2 ± 6.40 µg/m 3 ). Aldehydes, in particular benzaldehyde that is often present in personal care products (ie, flavoring and denaturant agents) or household products, as previously observed, represent a source of these pollutants in the indoor air.…”

Indoor levels of volatile organic compounds at Florentine museum environments in Italy

Indoor Air Quality monitoring in cultural institutions is of particular concern to protect these places and the cultural heritage content. An indoor monitoring campaign was performed in three museums in Florence (Italy) to determine the occurrence and levels of volatile organic compounds (VOCs). VOCs of interest included BTEX (benzene, toluene, ethylbenzene, xylenes), terpenes, aldehydes, organic acids, and cyclic volatile methyl siloxanes (cVMS). The most abundant VOCs in all samples analyzed were BTEX, which were strictly related to the traffic source, followed by siloxanes and terpenes. Among BTEX, toluene was always the most abundant followed by xylenes, ethylbenzene, and benzene. cVMS in exhibition rooms with the presence of visitors showed higher values compared to samples collected when the museums were closed. Terpenes showed not only the influence of vegetation‐biogenic sources surrounding a museum but could also be related to the wood used for the construction of showcases and furniture and the use of cleaning products. Data obtained also showed the presence of organic acids and aldehydes whose source can be traced back to exhibits themselves and wood‐based furniture. Assessing the levels of organic acids in museums is important because, over time, it can cause deterioration of the artifacts.

“…This applies for typical solvents such as dichloromethane, 1‐ and 2‐propanol, methyl acetate, 1‐ and 2‐butanol, 2‐butanone, tetrahydrofuran, 2 and 3‐methyl pentane, acetonitrile, and dimethylformamide. The substances can be found in diverse chemical products such as paints, waxes, adhesives, sprays, and cleaning materials (Ayoko, ). Table shows, where possible, potential sources and references for the individual substances.…”

Very volatile organic compounds (VVOCs), as categorized by the WHO, are an important subgroup of indoor pollutants and cover a wide spectrum of chemical substances. Some VVOCs are components of products commonly used indoors, some result from chemical reactions and some are reactive precursors of secondary products. Nevertheless, there is still no clear and internationally accepted definition of VVOCs. Current approaches are based on the boiling point, and the saturation vapor pressure or refer to analytical procedures. A significant problem is that many airborne VVOCs cannot be routinely analyzed by the usually applied technique of sampling on Tenax TA â followed by thermal desorption GC/MS or by DNPH-sampling/ HPLC/UV. Some VVOCs are therefore often neglected in indoor-related studies. However, VVOCs are of high significance for indoor air quality assessment and there is need for their broader consideration in measurement campaigns and material emission testing.

Practical ImplicationsSo far, many very volatile organic compounds (VVOCs) are insufficiently considered, although they are of importance for the evaluation of indoor air quality and building product emissions. Moreover, an appropriate definition of VVOCs does not exist. Therefore, it is the purpose of this publication to shift VVOCs more into the focus of indoorrelated research. Potential VVOCs, their sources, indoor air concentrations, and analytical procedures are critically discussed.

“…Indoor VOCs generally originate from four sources: (i) off-gassing from building materials, (ii) entrainment of outdoor air through ventilation and infiltration, (iii) production from indoor chemical reactions, and (iv) indoor human activities (Finlayson-Pitts and Pitts, 2000), such as smoking (Jia et al, 2008;Rothberg et al, 1998), cooking (Huang et al, 2011), and the use of household cleaning and personal care products (Ayoko, 2009;Nazaroff and Weschler, 2004). Each of these sources generates hundreds of VOCs (Amann et al, 2014;Brown et al, 1994;Tuazon et al, 2000;Yu and Crump, 1998).…”

Contribution of human-related sources to indoor volatile organic compounds in a university classroom

et al. 2015

Although significant progress has been made in understanding the sources and chemistry of indoor volatile organic compounds (VOCs) during the past decades, much is unknown about the role of humans in indoor air chemistry. In the spring of 2014, we conducted continuous measurements of VOCs using a proton transfer reaction mass spectrometer (PTR-MS) in a university classroom. Positive matrix factorization (PMF) of the measured VOCs revealed a 'human influence' component, which likely represented VOCs produced from human breath and ozonolysis of human skin lipids. The concentration of the human influence component increased with the number of occupants and decreased with ventilation rate in a similar way to CO , with an average contribution of 40% to the measured daytime VOC concentration. In addition, the human skin lipid ozonolysis products were observed to correlate with CO and anticorrelate with O , suggesting that reactions on human surfaces may be important sources of indoor VOCs and sinks for indoor O . Our study suggests that humans can substantially affect VOC composition and oxidative capacity in indoor environments.
