2-乙基-1-己醇是一种可能的致病化学物质，尽管在室内空气污染研究中，2-乙基-1-己醇作为一种有害物质很少受到关注。从2002年到2004年，在日本名古屋42栋非住宅建筑的99个房间中测量了空气中2-乙基-1-己醇的浓度。扩散采样法是测量室内空气中低浓度2-乙基-1-己醇的有效方法。室内空气中2-乙基-1-己醇浓度的几何平均值（几何标准差）为16.5 (5.4)μ m(-3)，室外空气中2-乙基-1-己醇浓度为1.9 (2.2)μ m（-3）。室内空气和室外空气中2-乙基-1-己醇的最大浓度分别为2709 μ m（-3）和12.4 μ m（-3）。在少数新建筑物中，较少的房间显示出高浓度的2-乙基-1-己醇，而在这些建筑物的许多房间以及其他新建筑物中观察到低浓度。每栋建筑中2-乙基-1-己醇的室内浓度差异很大。室内空气中2-乙基-1-己醇浓度的几何平均值显著高于室外空气（p < 0.01）。室内与室外空气中2-乙基-1-己醇浓度相关性不显著。机械通风对暂时降低室内2-乙基-1-己醇水平有效。这些结果表明，2-乙基-1-己醇的主要来源是室内。
2-Ethyl-1-hexanol is a possibly causative chemical in sick building symptoms, although 2-ethyl-1-hexanol has received little attention as a hazardous substance in studies on indoor air pollution. Airborne 2-ethyl-1-hexanol concentrations were measured from 2002 to 2004 in 99 rooms of 42 non-domestic buildings in Nagoya, Japan. The diffusive sampling method is effective for the measurement of a low level of 2-ethyl-1-hexanol in indoor air. The geometric mean (geometric standard deviation) of 2-ethyl-1-hexanol concentrations was 16.5 (5.4) microg m(-3) in indoor air and 1.9 (2.2) microg m(-3) in outdoor air. The maximum concentration of 2-ethyl-1-hexanol in indoor air and outdoor air was 2709 microg m(-3) and 12.4 microg m(-3), respectively. Fewer rooms in a small number of new buildings showed high concentrations of 2-ethyl-1-hexanol, while low concentrations were observed in many rooms of these buildings as well as the other new buildings. The room-to-room concentrations of 2-ethyl-1-hexanol in each building exhibited a wide variation. The geometric mean of the 2-ethyl-1-hexanol concentrations was significantly higher for indoor air than for outdoor air (p < 0.01). The correlation of the 2-ethyl-1-hexanol concentrations between indoor and outdoor air was not significant. Mechanical ventilation was effective in the temporary reduction of indoor 2-ethyl-1-hexanol level. These results suggest that the predominant source of 2-ethyl-1-hexanol was indoor areas.
