Title: Formaldehyde surface emission monitor

Abstract

A passive surface emission monitor has been developed for nondestructive measurement of formaldehyde (CH/sub 2/O) emission rates from CH/sub 2/O resin-containing materials such as urea-formaldehyde foam insulation (UFFI) and pressed-wood products. Emitted CH/sub 2/O is sorbed by a planar distribution of 13X molecular sleve supported inside the monitor and analyzed by using a water-rinse desorption, colorimetric analysis procedure. A detection limit of similarly ordered 0.025 mg of CH/sub 2/O/(M/sup 2/ h) is achieved with a 20.3 cm diameter monitor and a 2-h collection period. Measurements of CH/sub 2/O emission rates from pressed-wood products and UFFI encased in simulated wall panels show a strong correlation with reference chamber techniques. The surface monitor has been used to measure the CH/sub 2/O emission rate from interior walls and floors in one UFFI and two non-UFFI homes. By application of a simple single compartment model to predict indoor CH/sub 2/O concentrations from in situ CH/sub 2/O emission rate and tracer gas infiltration rate measurements, a good correlation between the predicted and measured CH/sub 2/O concentrations was achieved. 22 references, 5 figures, 4 tables.
