Evaluation of formaldehyde emissions from composite wood products

Abstract Regarding undesired effects of formaldehyde on the health of people and enviroment, it is desired to evaluate the amount of emission of this gas from a wood composite product in order to introduce a practical method for evaluating the amount of it,s emission from any other wood product. To...
