IHMod — software to characterise chemical risk

The spreadsheet contains several algorithms for calculating/estimating airborne concentrations of chemicals. Each equation included in the spreadsheet has been described in the literature. The spreadsheet was developed by the American Industrial Hygiene Association and was translated by to several languages, e.g. to French by the National Institute of Research and Security (INRS). It is also included in the SEIRICH tool for level-3 expert users.
