A formaldehyde surface emission monitor is under development for passive, non-destructive measurement of formaldehyde (CH/sub 2/O) emission rates from flat surfaces of solid CH/sub 2/O sources. The monitor utilizes a solid sorbent, 13X molecular sieve, that provides excellent chemical stability for sorbed CH/sub 2/O and permits the monitor to be used in any physical orientation. With a 0.032 m/sup 2/ test area, a approx. = 0.01 mg CH/sub 2/O/m/sup 2/.hr detection limit can be achieved with a 3-hr sampling period and pararosaniline colorimetric analysis. Preliminary results indicate that the monitor could be used for (1) quality control measurements of commercial CH/sub 2/O resin-containing materials such as pressed-wood products, and (2) in-situ measurements of CH/sub 2/O emission rates from a variety of CH/sub 2/O sources in domestic environments such as pressed-wood, textiles, and urea-formaldehyde foam insulation products.
