Effects of Bake Out As a Source Control Technique for Indoor Chemical Substances (PART 1) A study on indoor air pollution by VOC and formaldehyde (Part 2)

摘要

Indoor air pollution caused by the chemical substances such as formaldehyde and volatile organic compounds (VOCs) is a serious problem in Japan. Even if the emission rates of chemical substance are small, the concentration shows a tendency of high levels due to the increase of the air-tightness in residences. Bake-out might be a novel approach to reduce formaldehyde or VOC levels in a new residence. Bake-out is based on the theory that vapor pressure from building materials will be increased by elevating temperature in rooms.
