New building materials, products, and furnishings are known to emit a large number of organic chemicals into indoor air. The author addresses the effects of volatile organic compounds (VOCs) on building occupants, including building materials evaluation and strategies to reduce airborne concentrations. A major problem is that little is known about the specific health effects of most VOCs at the low concentrations usually found in indoor environments.

Asthma, wheezing, and allergies in Russian schoolchildren in relation to new surface materials in the home.

In a cross-sectional study of 5951 Russian 8-12-year-old schoolchildren, risks of current asthma, wheezing, and allergy were related to recent renovation and the installation of materials with potential chemical emissions. New linoleum flooring, synthetic carpeting, particleboard, wall coverings, and furniture and recent painting were determinants of 1 or several of these 3 health outcomes. These findings warrant further attention to the type of materials used in interior design.

Material Emission Rates : Literature Review, and the Impact of Indoor Air Temperature and Relative Humidity

An extensive literature review of research on the impact of indoor air conditions; temperature, relative humidity and surface air velocity on materials emission rates is presented. This paper also presents the results of an experimental work to study the impact of room air temperature and relative humidity on materials emission rates. The results indicate that both the temperature and relative humidity have a significant effect on the emissions from paint and varnish. In the case of varnish, the results were consistent with earlier results. However, the paint results show inconsistent emission behaviour. Further, for both materials, the individual compounds did not necessarily follow the same trend established for the TVOC.

Emissions from freshly applied paints and other coatings can cause elevated indoor concentrations of vapor-phase organics. Methods are needed to determine the emission rates over time for these products. Some success has been achieved using simple first-order decay models to evaluate data from small dynamic test chambers. While such empirical approaches may be useful for assessing the emission potmial of indoor sources, a more fundamental approach is needed to fully elucidate the relevant mass transfer processes. As a first step, a simple model based on boundary layer theory has been developed. In this model, the mass transfer rate is assumed to be controlled by the boundary layer mass transfer coefficient, the saturation vapor pressure of the material being emitted, and the mass of volatile material remaining in the source at any point in time. Static and dynamic chamber tests and test house experiments were conducted to obtain model validation data, Preliminary validaion results indicated that the model can be applied to different products with similar solvents. The model provides a better fit to chamber-derived emissions data than the empirical first-order decay model, especially over the decaying portion of the concentration vs. time curve
