This paper describes the emissions of Volatile Organic Compounds (VOC) emitted by solid Spruce (Picea abies) and Poplar (Populus alba) wood treated at 200 °C and 180 °C. The emissions of VOC from heat treated wood and air-dried (natural) wood were compared with GC-MS analysis. The focus was on the infl uence of temperature, on the quality and quantity of volatile organic compounds, especially on the amount of emitted phenol and furfural. Furfural and phenol are typical chemicals produced as a result of thermal degradation of wood components. The emission was analyzed as a function of time after heat-treatment. The infl uence of the fi nishing with waterborne lacquer on VOC emission was also investigated. The results of this research have shown that heat treated wood emitted more VOC-components of furfural and phenol than untreated wood (natural wood). The amount of emitted VOC declines with increasing the time between wood modifi cation and measurement of VOC emissions emitted by tested samples. Heat treated wood fi nished by waterborne lacquer emitted a very high concentration of Buthoxy-ethanol. The fi nished surface does not decrease the amount of emissions escaping from heat-treated spruce and poplar wood.
This article addresses the issue of VOC emissions from upholstery materials (natural leather) used for the manufacturing of upholstered furniture. The main intention of this paper is to compare VOC emissions released from different types of natural upholstery leathers. This research has assessed the impact of various factors (e.g. the organic origin of leather, the type of tanning, the type of upholstery leather and the leather finish etc.) on the amount of VOC emissions from natural leathers used for the production of upholstered furniture. 1 m 2 samples of natural leather were prepared for testing before being placed into a small test chamber (1 m 3 volume). VOC emission measurements were taken in a small test chamber with predefined conditions (an ambient temperature of 23ºC and 50% relative air humidity). With the use of sorbent Tenax TA were, the values of VOC emissions released by the test sample of different types of leather into desorption tubes was then recorded. VOC emissions were analysed in an Agilent GC 6890 N gas chromatograph using an Agilent 5973 Network mass spectrometer using cryofocusing, thermal desorption and a GC-MS data library (NIST 05). The analyses conducted provide qualitative and quantitative data regarding the concentration of selected VOC representatives measured in µg.m -3 . The quantitative difference in all emitted organic compounds is shown by the measured values of the TVOC parameter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
