“…All of these factors could importantly contribute to the distribution of PCP between wood, air, and SPME fiber and consequently affect the results. It has been recently shown that SPME sampling in open areas of museums can lead to very high RSDs [ 57 ]. In addition to PCP, lindane and dibutyl phthalate (DBP) were also identified in the HS SPME chromatogram based on NIST spectral library ( Figure 8 ).…”

Non-Destructive Detection of Pentachlorophenol Residues in Historical Wooden Objects

Wood is a natural polymeric material that is an important constituent of many heritage collections. Because of its susceptibility to biodegradation, it is often chemically treated with substances that can be harmful to human health. One of the most widely used wood preservatives was pentachlorophenol (PCP), which is still present in museum objects today, although its use has been restricted for about forty years. The development of non-destructive methods for its determination, suitable for the analysis of valuable objects, is therefore of great importance. In this work, two non-destructive solid-phase microextraction (SPME) methods were developed and optimized, using either headspace or contact mode. They were compared with a destructive solvent extraction method and found to be suitable for quantification in the range of 7.5 to 75 mg PCP/kg wood at room temperature. The developed semi-quantitative methods were applied in the wooden furniture depot of National Museum of Slovenia. PCP was detected inside two furniture objects using headspace mode. The pesticide lindane was also detected in one object. The indoor air of the depot with furniture was also sampled with HS SPME, and traces of PCP were found. According to the results, SPME methods are suitable for the detection of PCP residues in museum objects and in the environment.

“…Recently, Kearney et al showed the utility of SPME fibres for sorption of phthalates emitted from a visibly degraded object where it was not possible to sample via contact [4]. However, the variability of measurements in noncontrolled museum environments discounts their use in quantitative studies [96]. GC/MS analysis of analytes captured in passive samplers (sorbent tubes, activated charcoal disks, SPME fibres) from sealed chamber emission studies have also been used for measurement of key parameters (y 0 and K m ) to model semi-volatile phthalate migration from vinyl flooring at 25 °C [97].…”

Plasticiser loss is a topic frequently mentioned in discussions on the degradation of plastic artefacts in museum collections, particularly for plasticised poly (vinyl chloride) and cellulose acetate. Plasticisers may migrate to the plastic’s surface and remain as a deposit, or volatilise into the surrounding environment, both presenting an aesthetic issue and impacting the future stability of the plastic. This paper draws on the work of conservation science, materials degradation, and indoor air quality/emissions studies, to review our current understanding of plasticiser loss. The influence of the material’s intrinsic properties, and environmental factors on migration rates are discussed and related to preventive conservation practices. The methods by which plasticiser migration is studied, including characterisation, are also reviewed, with a particular focus on minimally invasive and non-destructive methods suitable for heritage science research.

“…The duration of sampling depends on the application. For laboratory sampling in closed vials, 1 h sampling is commonly used [88,89], while for bulk air sampling of rooms, studies have shown examples of 1 day sampling up to 15 days [86,88,90], with 1 day recommended to obtain the best repeatability [10]. SPME Arrow is a fibre with a larger surface area that allows for higher capacity and analyte extraction compared to conventional SPME fibres [91][92][93].…”

“…2024, 14, 4620 2 of 19 The identification and quantification of VOC species is crucial, as volatiles can be highly reactive [7]. The study of emissions from historic objects provides information about the materials and their degradation processes [9][10][11], which could include biologically formed VOCs as a consequence of metabolic processes. This could mean that the detection of VOCs could be used as a chemical marker to detect the presence of biodeteriogenic pathogens at early stages, even before the consequences of biodeterioration become visible [12,13].…”

In the recent years, there has been an increased interest in indoor air quality in heritage environments, specifically in relation to volatile organic compounds (VOCs). These could originate from objects, furnishings, visitors and staff, as well as from olfactory exhibitions. This interest led to a number of studies investigating the “typical” emissions for diverse materials and their impact on the surrounding environment. The analysis of volatile compounds emitted by objects helps in the characterization of the material composition, its conservation history or its degradation processes. This contribution reviews how volatiles are emitted from objects and the commonly used sampling techniques for heritage science applications. A variety of methods are available, from bulk air sample collection to preconcentration using samplers. The commonly studied object types contributing to indoor VOCs are discussed. These include emissions from heritage objects, conservation products, furnishing materials and display cases. Furthermore, olfactory exhibitions are discussed in terms of indoor air quality. Finally, the findings are compared with the current guidelines on indoor volatile concentrations.
