Description
The process of monitoring of volatile organic compounds present in indoor air at a newly constructed building was undertaken in 2015. We detected 2-butanone oxime at a maximum concentration of 3,570 g/m3. The emission source of 2-butanone oxime was silicone sealant used in the construction of the building. The adsorption of 2-butanone oxime with thermal desorption using a Tenax TA sampler was suitably accurate to trap 2-butanone oxime under both low- and high- humidity conditions. It was confirmed that 2-butanone oxime was stable under high humidity (relative humidity: 80%), and the Tenax TA sampler, with a flow rate of 0.1 L/min, was able to stably measure data for 2 h. The emission source of both 2-butanone oxime and 2-butanone was a silicone sealant used in the building. This was determined by placing a glass plate coverd with the silicone sealant in a Tedlar® Bag for 2 weeks, and analyzed by Gas chromatograph/Mass spectrometer (GC/MS). Air in a Tedlar® Bag was sampling every other day throughout the 2-week period. A maximum concentration of 2-butanone oxime was observed after approximately 1 week, and it gradually decreased thereafter. The concentration of 2-butanone in the bag gradually increased throughout the sampling period; however, its production rate was low in comparison to the decline rate of 2-butanone oxime.
