The paper discusses methods for characterizing chemical emissions from material sources, including laboratory, dynamic chamber, and full-scale studies. Indoor sources and their interaction with sinks play a major role in determining indoor air quality (IAQ). Techniques for evaluating the behavior of indoor sinks are presented. Procedures for analyzing chamber test data to produce emission rates and adsorption/desorption rate constants are discussed, as is the use of these results in IAQ models to predict occupant exposure. Thoughts on how to link biological responses to source and sink emissions are presented, and source testing methods based on biological responses are briefly touched on. Finally, recommendations for future research are given.
