By the analysis of formaldehyde emitted from 11 types of artificial wood-based boards taken from construction market in Wuhan city,the results showed that the emission concentrations have notably varied along with time. Short-term and long-term emission models according to chamber concentrations by using the Exponential Decay 1 Model in Origin 4.1 software were established. The short-term model reflected the concentration variation well for hours at beginning, and the long-term model not well...
