TodayFirst draft handbook, the over 50 volunteers that are working on the first International Handbook on the Assessment of Odour Exposure by using Dispersion Modelling reached their first milestone. The first draft of this handbook, was just released (only available for the volunteers) and it has, at this stage, 289 pages of information on the topic.

   The group has had already 20 monthly meetings since the very first meeting took place the 27th of August 2020. This development is being led by Ms. Jennifer Barclay, principal scientist of Atmospheric Science Global (ASG) in New Zealand and Dr. Günther Schauberger, professor of the University of Veterinary Medicine of Vienna, Austria.

Weber-Fechner Curve    An Energy Development Facility (EDF) has been evaluated as an odor source to optimize the evaluation of odor persistency. The objectives were to identify the odor characteristics and intensity from the EDF and to determine the relative contribution and variability of the different odors emitted.

   The method includes using the Odor Profile Method to identify each odor character and intensity and using olfactometry as an odor dilution system to determine the persistency of the odor, i.e., the rate of decrease of an odor with dilution. The results showed that air coming from the EDF can pose a rancid and sweet odor nuisance for the community near the EDF and possibly a weak musty odor nuisance for the area further away from the EDF. 

48 006a   An Odour Attribution Study is undertaken in North America for an Air Quality Management Agency that includes athering data from specific sources and ambient locations to better understand odour impacts within the local communities. Specifically, the following objectives were to be met:

  Identify odorant compounds impacting the area of concern via comprehensive quantitative and qualitative analyses; Determine the relative contribution and variability of the odorant compounds emitted from the three key source facilities; Develop a strategy for continuous real-time odorant monitoring to measure emissions impacting the community from the three key source facilities.
