Small chamber tests were carried out to compare the formaldehyde (HCHO) emission rate of Japanese Cedar and that of industrial wooden materials. Conventionally, it was clarified that Japanese Cedar emitted less HCHO than the value of the best grade, as defined by the regulations for interior materials. However, the HCHO emission rates of 2 identical specimens under the same testing conditions were significantly different, with the drying temperature of the specimens considered as a primary factor for their preparation. Japanese Cedar and German Spruce were dried under 3 different conditions and examined in small chambers. The results show that the HCHO emission rate of different species is affected by the drying temperature and that solid wood dried at high temperatures emits more volatile organic compounds (VOCs) than that dried at low temperatures., http://ci.nii.ac.jp/naid/110006989924}, pages = {1267--1273}, title = {木材由来の化学物質放散速度に対する乾燥温度の影響について}, volume = {73}, year = {2008}, yomi = {ハセガワ, アサコ} }
