Olfactometry Services and Expertise
For over 25 years, AtmoDC has acquired expertise in olfactometry and odour management. By mastering all the stages involved in developing a odor or gaseous contaminant emission management plan, our team of engineers, scientists, and technicians supports clients from project initiation through to the final report.
Environmental compliance for industrial and commercial gaseous emissions, as well as community complaints regarding ambient odors, remain the primary motivations for corporate decision-makers to undertake atmospheric dispersion modelling. With in-depth knowledge of the laws and regulations governing odour emissions in Quebec and Canada, AtmoDC provides its clients with modelling-based strategies that maintains optimal operational flexibility while ensuring environmental compliance for industrial facility gas emissions.
Regardless of the type of emission source, whether it involves material handling, food processing and cooking operations, chimneys, tanks, basins, reservoirs, fugitive emissions, or waste and wastewater treatment facilities, AtmoDC offers sampling, characterization, and odor and other contaminants dispersion modeling services to recommend control strategies tailored to the client’s operational needs.

Odour control strategies need a systematic approach.
Odour and emission sampling
AtmoDC is equipped with a wide range of specialized sampling equipment, allowing methods to be adapted to the client’s specific needs, whether sampling point, surface, or volumetric sources. AtmoDC is also equipped with wind tunnels that simulate the dispersion of a product over a surface.
Olfactometric analysis and odour characterization
Olfactometric analyses provide information on the characteristics of sampled odours. AtmoDC laboratories are equipped with Onose-8®, a state-of-the-art stationary dynamic dilution olfactometer. Designed, manufactured, and operated by AtmoDC engineers and scientists, Onose-8® is one of the most precise, consistent, and reliable olfactometers produced in Canada.
Atmospheric Dispersion Modelling
Once odor or gaseous contaminant source samples have been collected and analyzed, the results can be incorporated into an atmospheric dispersion model to predict their potential nuisance impact on the surrounding area, based on prevailing wind.
Dispersion models generally allow to:
- Verify a plant’s emissions compliance with current air quality regulations.
- Identify the impacts of odor and contaminant sources’ emissions on the neighborhood.
- Determine the level of attenuation required to practically eliminate all odor or contaminant issues in the neighborhood.
- Optimize odor and contaminant reduction efforts and investments in contaminant and odor reduction technologies or techniques.
- Verify the dispersion of odors and other atmospheric contaminants, as well as produce emission dispersion figures in order to optimize the location of a new installation or plant and perform air quality impact studies.
