We have compiled a variety of resources on relevant exposure-related topics, including information useful to our neighbors in the community and to occupational health and safety professionals.

EXPOSURE ASSESSMENT TOOLS
Industrial hygienists (IHs) need objective methods for estimating occupational exposure when exposure monitoring data are unavailable. This tool, currently an Excel based spreadsheet has been shown to be very helpful in guiding professional judgment leading to more accurate exposure judgments. A web-based version that could be used on a smart phone or device would be very useful to practitioners. We are planning to develop this tool for implementation on several platforms.
This tool was developed to facilitate a complete and consistent approach to basic characterization. It serves to collect and organize information in formats typically needed for modeling exposures and applying statistical tools when exposure measurements are collected. The file can be renamed for document retention purposes.
The IHMOD 2.0 and support file provide a range of mathematical models that are useful for estimating airborne exposure to chemical contaminants. These freely available spreadsheet tools are described at ihmod.org and the models have been evaluated by our team.
