Abstract
The rising popularity of various types of wood panels and the advances in manufacturing technology have increased the uses of wood. The bonding of fibers and particles to form panels, however, involves impregnation with resins, such as phenolic adhesives, which delivery desirable quality to the panels due to their insolubility in water, resistance against heat among others, but are also recognized as carcinogenic to humans (IARC, 2004International Agency for Research on Cancer.

). This study involved measuring the levels of formaldehyde, remaining in wood panels after use and disposal. It was initially evaluated new panels and then examined degraded ones. The results demonstrated significant volatilization of formaldehyde during the degradation process of the panels, with losses of 74.83% for MDF and 85.71% for medium density particleboards (MDP).
