|Program PARAMS User’s Guide, Program Version: 1.0, Document Version: 1.0 (EPA/600/R-05/066) March 2005
This Microsoft Windows-based computer program implements 30 methods for estimating the parameters in indoor emissions source models, which are an essential component of indoor air quality (IAQ) and exposure models. These methods fall into eight categories:
Potential users include those who develop or use IAQ and exposure models and those who develop or use quantitative structure-activity relationship (QSAR) models. In addition, many calculations are useful to researchers in areas other than indoor air quality. Users can benefit from this program in two ways. First, it serves as a handy tool by putting commonly used parameter estimation methods in one place. Second, it saves users time by taking over tedious calculations. It should be pointed out, however, that the methods implemented in this program cover only a fraction of the parameters that appear in the more than 50 indoor emission source models. Furthermore, the methods in the current version are mostly for gaseous pollutants; those for particulate matter are not included.
