“…In those indoor or enclosed environments, the emitting materials of volatile organic acids (and aldehydes) may vary. Among these wood-based materials, glues, paints, and varnishes, that are part of the compartments (e.g., cabinets, boxes, and drawers) or supporting structures (e.g., shelves) that are used to exhibit or store the objects are included (Clarke & Longhurst, 1961;Ryhl-Svendsen & Glastrup, 2002;de Thickett & Lee, 2004;Robinet & Thickett, 2005;Grzywacz, 2006;Gibson & Watt, 2010;De Laet et al, 2013;Faria et al, 2013;Prosek et al, 2014). In addition, the wood materials that are used to protect or to improve the esthetic aspect of the metal object, or that are part of it (e.g., wood sections of weapons or tools) can also be important sources of contamination, especially when in direct contact with the object (Deflorian & Fedel, 2013).…”
