This webinar will be a presentation for Industrial hygienists who may have heard of exposure modeling but are worried that their last math and chemistry courses were long enough ago that modeling is out of their reach. It will inform Industrial hygienists whose day-to-day tasks keep them from practicing the mathematics that seem front-and-center in exposure modeling and it will help Industrial hygienists who know that they have the skills needed to use models for exposure assessment, but don’t know how to get started. This webinar is intended to be an easy “on ramp” into the world of modeling using basic scenarios and models, it and will point the way forward to more in-depth model use.
