The Combined Effects of Temperature and Humidity on Initial Emittable Formaldehyde Concentration of Fiberboard

Individual effects of temperature and humidity on formaldehyde emissions from manufactured fiberboards have been studied previously, but their combined effects and possible correlation with initial emittable concentration (C0) of building materials have not been reported. This project investigates combined effects theoretically from a microcosmic perspective. A correlation between C0 and the combined effects of temperature and humidity is derived. The correlation could be helpful to estimate indoor formaldehyde exposure under varied temperature and humidity conditions in actual buildings. Influences of using different token parameters of humidity are also analyzed.
