Odour Source

Overview

A location or object that emanates odours. Sources can be divided by point, area, or volume sources that are of either passive, active or fugitive type. For example, a rectangular oil pond would be labelled as a ‘passive area source’ and a biofilter may be labelled as an ‘active area source.’ The term diffuse source is used to describe area or volume sources. Fugitive samples are essentially unintended releases of odour. A summary is shown below:

Point source > Passive or active or fugitive

Diffuse source  > Area source or volume source  > Passive or active or fugitive
