Indoor Chemical Exposure Classification/Ranking Model (ICECRM)
The ICECRM model considers the following “indirect” chemical exposure pathways to humans: 1) inhalation of gaseous and particulate chemicals in indoor air, 2) non-dietary ingestion of dust and through hand-to-mouth contact following indoor surface contact, and 3) dermal permeation. The model equations, formulated in fugacity notation and programmed in Visual Basic for Application (VBA) in Excel™, quantify chemical transport, degradation, distribution and exposure processes for up to 10,000 chemicals at a time. Full details of the model are available in the following publication:

The ICECRM model is implemented (coded) in Visual Basic for Applications (VBA) and the Graphical User Interface is designed in Excel™. A User Manual is embedded within the Excel file. The ICECRM model will only function properly on a Windows operating system. The computer must use the period (.) as the decimal separator rather than the comma (,) to ensure accurate results.
