木質材料有機物揮發與其影響人類健康之研究
BVOC EMISSION FROM WOODY MATERIALS AND ITS EFFECT ON HUMAN HEALTH
摘要
揮發性有機化合物(Volatile organic compounds, VOC)通常係指人為排放的揮發性有機物，近年來由於環保意識覺醒，對於環境中揮發性有機物之排放，及其排放的相關規範標準皆逐漸受到重視。而生物源揮發性有機化合物(Biological volatile organic compound, BVOC)則係指生物代謝所排放的VOC，屬於植物的二次代謝物。木材屬於一種生物性材料，具有揮散出此類代謝物之能力，不同於一般建材釋出的VOC，這些芳香氣息係儲存於木材內部，因成分的高揮發性、低沸點而由材面自然釋出，因此隨者木材加工程度的不同，在室內使用的木質地板、壁板、家具及木器等木質材料之加工產品都將具有類似之揮發性。針葉樹材之揮發物以α-Pinene等單類為主，本次回顧之闊葉樹材揮發性則較不明顯，在環境溫度50 ℃時會有喃類的纖維素裂解物釋出，而木質人造板材之VOC則常以醛類物質為主。因此木質材料的選用，其揮發性會直接影響室內空氣品質，人造板材釋出之VOC則多為空氣污染物，而實木材質BVOC之釋出對於人體有何種實際助益仍待進一步的研究。

The emission issue of volatile organic compounds (VOC) has been taken notice by the public in recent years, because it may change the indoor air quality and affect human health. Biological VOC (BVOC) is one kind of VOC mostly emitted from plant synthesis, which is classified as secondary metabolites. It is called phytoncide when human engage activities in forest. Wood is a biological materials, and has the propensity to emit the volatile content. BVOC is different from the VOC which emit from solvent or coating. Indoor use of wooden ware, flooring, siding, furniture and decorations have the ability to emit the fragrant smell, to sublimate as BVOC. In this review, the VOC emission from softwood is mainly α-pinene and other monoterpenes. The VOC emission from hardwood is not significant, but these are some furan emission when the background temperature is higher. The VOC emissions from woodbased panel is mainly aldehydes. Therefore, the emission status of the wood materials would directly affect the indoor air quality. The emission from wood-based panel mainly contributes to air pollution. The health effect of BVOC emission from solid wood on human should be clarified in the future.
