Abstract : The current emphasis on the irritant and possible health effects of atmospheric formaldehyde in manufactured housing has placed an additional burden on the industry to reduce formaldehyde liberation to a reasonable level. The extensive use of materials containing formaldehyde in manufactured housing compounds the problem and demands a broad testing program. To meet the needs of this program, a colorimetric method of determining formaldehyde levels using Purpald reagent was modified for field testing. This method produces fast, accurate, on-the-spot readings, which provides a valuable tool in determining the sources and conditions of formaldehyde liberation in mobile homes. This test method is described and its advantages and limits are discussed. Data gathered by this method are also presented, including the relationship of vapor pressure to the migration patterns of atmospheric formaldehyde in a conventional mobile home. Extensive testing has also been very helpful in determining the effectiveness of various retrofit methods of formaldehyde reduction where complaints exist. The effectiveness of coating or sealing materials, reduction with ammonium hydroxide, and increased ventilation are also discussed. (Author)
