Odour Source

Odour Source

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
