Definition

“FIDOL factors” in the context of odour assessment and management are used to describe the various attributes and characteristics of odours. The acronym “FIDOL” typically stands for the following factors:

1. Frequency: Refers to how often the odour occurs, whether it is continuous, intermittent, or occasional.

2. Intensity: Indicates the strength or concentration of the odour, whether it is weak, moderate, strong, or pungent.

3. Duration: Describes how long the odour persists, whether it is brief, lasting, or prolonged.

4. Offensiveness: Relates to the level of offensiveness or unpleasantness of the odour, which can vary from barely noticeable to highly objectionable.

5. Location: Specifies where the odour is originating from and where it is perceived, as well as whether it is localized or dispersed.

These factors are used to assess and characterize odours, helping in odour impact assessments, mitigation strategies, and regulatory compliance in situations where odours are a concern, such as in industrial, environmental, or community settings. Understanding FIDOL factors is valuable for managing and addressing odour-related issues effectively.
