“…However, the equilibrium concentration of formaldehyde increased with an increase in temperature. Andersen et al 21 conducted field and chamber experiments on formaldehyde emissions from particle board. These chamber experiments showed that the emissions had a strong positive correlation with the prevailing temperature and humidity conditions.…”

The effect of temperature and humidity on formaldehyde emissions from samples collected from temporary housing units (THUs) was studied. The THUs were supplied by the U.S. Federal Emergency Management Administration (FEMA) to families that lost their homes in Louisiana and Mississippi during the Hurricane Katrina and Rita disasters. On the basis of a previous study, four of the composite wood surface materials that dominated contributions to indoor formaldehyde were selected to analyze the effects of temperature and humidity on the emission factors. Humidity equilibration experiments were carried out on two of the samples to determine how long the samples take to equilibrate with the surrounding environmental conditions. Small chamber experiments were then conducted to measure emission factors for the four surface materials at various temperature and humidity conditions. The samples were analyzed for formaldehyde via high-performance liquid chromatography. The experiments showed that increases in temperature or humidity contributed to an increase in emission factors. A linear regression model was built using the natural log of the percent relative humidity (RH) and inverse of temperature (in K) as independent variables and the natural log of emission factors as the dependent variable. The coefficients for the inverse of temperature and log RH with log emission factor were found to be statistically significant for all of the samples at the 95% confidence level. This study should assist in retrospectively estimating indoor formaldehyde exposure of occupants of THUs.

“…The rate of release varies with temperature, humidity, light exposure, quality and age of components, formulation, and expertise of the installer (Hollowell et al, 1979a;Rumack, 1978). Andersen et al (1975) developed a mathematical model that reproduced the measurements of airborne formaldehyde in dwellings and in a climate chamber containing chipboard, with correlation coefficients of 0.88 and 0.94, respectively. There are no studies that document the contribution of permanent-press fabrics and other textiles to formaldehyde concentrations in domestir environments.…”
