“…Following up, the emission of VOCs in case of pine wood can change depending on the sapwood or heartwood within the cross-section during drying. These findings are proved in the study of Sivrikaya et al [ 70 ]; the total VOCs emissions were considerably higher in air-dried heartwood (413.16 mg m −2 h −1 ) than in air-dried sapwood (32.89 mg m −2 h −1 ) of Scots pine ( Pinus sylvestris ). Especially, among the aldehydes, hexanal and pentanal were the dominating compounds.…”

“…In the case of volatiles emitted from the sample, plain headspace air sampling, or more often, equilibrium techniques are used, followed by the thermal desorption of collected compounds into the analytical system. This approach is often used for indoor air monitoring or emission rates of compounds from various materials [ 44 , 61 , 63 , 70 , 74 , 85 , 117 , 118 , 119 ]. For examples of the different analytical approaches and techniques used, see Table 2 .…”

“…The amount of compounds present in the solid material or emitted to the air can be expressed exactly using calibration curves or as an equivalent of one compound (e.g., toluene) [ 71 ]. For comparison, peak areas in the total ion current (TIC) chromatogram or sum of peak areas can be used [ 30 , 70 ].…”

“…Then, desorption temperatures depend on the sorbent type used and on compounds expected to be collected on the sorbent [ 30 , 71 ]. In addition, the desorption flow rate and time can vary, but they always have to ensure sufficient sample transfer from the sorption device to a GC inlet, while avoiding losses of volatile compounds [ 70 ]. Then, a cryofocusing unit is an important component for the cooling of an inlet of GC or the first part of the column to condensate compounds eluted from a sampling tube in the thermal desorption unit [ 120 ].…”

“…Peltier effect coller, liquid CO 2 , or nitrogen are usually used for cooling. After the cryofocusing period is terminated, volatiles are separated and detected using GC equipped with various detectors [ 70 , 74 ].…”

Volatile Organic Compounds (VOCs) from Wood and Wood-Based Panels: Methods for Evaluation, Potential Health Risks, and Mitigation

Volatile organic compounds (VOCs) are contained in various construction materials and interior equipment. Their higher concentrations in the indoor air are associated with negative effects on human health and are disputed in terms of health risk, since people spend a considerable part of their lifetime indoors. Therefore, the presence of VOCs in indoor air is a case of concern regarding sick building syndrome (SBS). From a historical point of view, wood and wood-based panels represent a widely used material. Nevertheless, wood appears to be nowadays a product and a material of a sustainable future. Depending on wood extractives’ composition and an abundance of diverse wood species, different profiles of volatiles are emitted. In case of wood-based panels, the impact of adhesives and additives that are essentially applied aiming to adjust the panels’ properties is even enriching this cocktail of chemicals. This paper comprises the issue of VOCs emitted from wood and wood-based panels. The most abundant VOCs were summarized. The options of VOCs for analytical determination from these matrixes are described with their benefits and limitations.

The influence of heat treatment severity (resulting from temperature) on the colour and gloss distribution changes of mahogany wood, and the effects of wood density on the responses to heat treatment were evaluated. The wood timbers with different densities were treated at 150 C to 200 C with an interval of 10 C and duration of 4 hours for heat treatment schedules. The colour parameters (lightness L * , red-green axis value a * , yellow-blue axis value b * ) and gloss (parallel and perpendicular to the grain) values of heat-treated wood were determined. The distributions of colour and gloss were analyzed using a frequency counts method. Results show that heat treatment resulted in the distinct decrease in L * and b * , while almost no change in a * for mahogany wood.The lower gloss values were obtained in the wood after heat treatment. The colour and gloss uniform on the exposed surface of the wood was improved due to heat treatment. Heat-treatment induced colour and gloss changes were more effective in the samples with lower density. The effects of density on the colour and gloss variability in the original wood were reduced by heat treatment, and this reduction was more distinct at high heat treatment temperature. The total gloss change was found to be highly correlated with the total colour change of heat-treated wood.
