Dioxin Emissions

 
 

Emissions Modeling

Emissions modeling from incinerators or other industrial (point sources) is often required to inform the exposure of human populations to hazardous compounds.  Generally, emissions modeling includes:


  1. ✓Collecting data of the dioxin emission profile from the stack

  2. ✓Information on the incinerator metrics (stack height, rate, etc...)

  3. ✓Defining the meteorological conditions (lower, upper atmosphere)

  4. ✓Selection of the dispersion model for emissions and deposition (Industrial Source Complex Model, AERMOD, etc...)

  5. ✓Congener-specific probabilistic estimation of emission plume dimensions, concentrations, and wet/dry deposition


To date we have applied these models to the emissions of the Dow facilities in Midland Michigan, and validated the predictions to soil concentration measurements.
