Odor Impact Studies

Applications:

  • Verification of facility compliance with current regulations
  • Estimation of level of abatement required to eliminate odor problem
  • Knowledge required to identify and choose the best reduction approach possible
  • Etc.

Modeling atmospheric dispersion of odors allows us to forecast impacts and olfactory nuisance factors associated with the odor sources under study.

This impact is quantified using atmospheric dispersion models such as AERMOD, CALPUFF, and TROPOS; the choice of model depends on a variety of factors (type of source under study, site topography, required level of result precision, or type of atmospheric contaminant under study).

The classic atmospheric dispersion models for contaminants do not allow sufficient simulation of atmospheric dispersion of odor. For this reason, Odotech performs simulations of atmospheric dispersion of odors using mathematical models specific to odors.

Our odor impact studies are designed and carried out according to a scientific method similar to that of impact studies conducted to study air quality. Using techniques and tools specific to odor, the odor impact study provides the information needed to assess and examine the impact of a project with respect to odor emissions. Its purpose is to help satisfy current regulatory requirements.
