Abstract

Large-scale multipollutant indoor air quality field studies must be designed and conducted to satisfy a broad array of scientific and programmatic interests of its sponsors. A comparative evaluation to identify critical factors associated with field study design, protocol, implementation, and data management problems and issues was done based on experiences of three multipollutant studies. These studies involved over 400 residences in the States of Tennessee, Alabama, Georgia, and Mississippi. Critical factors identified and discussed in this comparative evaluation are: factorial study design; participant selection and communications; interactive effects; regional and environmental variability; relational database management; new protocol evaluations; and multiple sponsor coordination. Field study data and methodologies are used to support and illustrate the comparative assessment of objectives and practices.
