Overview of Odors

COURSE NO: C02-043
Overview of Odors
Course Highlights

This online engineering PDH course provides guidance on a common problem facing environmental engineers and that is how to evaluate and treat an odor problem. Odors are not always toxic, but the nature of odors often causes people to act emotionally and demand that the source be eliminated. However, the nature of odorous compounds is that even a very low concentration can trigger detection or other reaction.


This course describes the nature of odorous compounds, how they are detected, their typical sources, and approaches and technologies commonly used to control them. It presents the factors and information necessary to assess an odor situation and how to approach it. It provides an overview of how to proceed in treating an odor episode and presents real life situations.


This 2 PDH online course is applicable to chemical and environmental engineers involved at the facility level to determine how to technically approach an odor episode and treat it effectively.
