在室内环境中经常观察到高浓度的乙醛。其中一个可能的来源是木质建材中乙醇产生的乙醛。为了表征室内乙醛的形成，并提出减少乙醛生成的方法，在室内进行了将乙醇添加到粉碎的固体木材中的实验。结果表明，乙醛是由添加乙醇的木材原料产生的，日本雪松、日本柏木和瑞典红木等针叶木材产生的乙醛比其他三种木材多。使用甲醇、乙醇、正丙醇和异丙醇等不同类型的醇进行的实验显示了与已报道的高等植物衍生酒精脱氢酶的酶谱相似的趋势。已证实，乙醛的生成可以通过通常用于灭活酶的处理方法来减少，即使用吡唑、硼酸盐和尿素的化学处理和热处理。研究结果表明，化学和热处理方法有助于减少室内环境中乙醛的产生。
High concentrations of acetaldehyde are often observed in indoor environments. One possible source of this is acetaldehyde formation produced by ethanol from wood building materials. To characterize indoor acetaldehyde formation and propose methods for its reduction, chamber-based experiments were conducted in which alcohols were added to pulverized solid woods. The results indicated that acetaldehyde was generated from the ethanol-added wood materials, and softwoods, namely Japanese cedar, Japanese cypress, and Swedish redwood generated more acetaldehyde than the other three woods. The experiments using different types of alcohols of methanol, ethanol, 1-propanol, and 2-propanol revealed a tendency similar to the reported enzymatic profile of the higher plant-derived alcohol dehydrogenase. It was confirmed that acetaldehyde generation was reduced by treatment methods typically used for inactivating enzymes, namely chemical treatments using pyrazole, borate, and urea and thermal treatments. The findings suggest that the chemical and thermal treatment methods are useful to reduce acetaldehyde generation in indoor environments.
