What is it?
The main idea of field inspections is to estimate the degree of annoyance in a determined problematic area by means of the olfactory capacities of a group of people (panel) specially trained and "calibrated" for this purpose.
Two different approaches for field inspection can be applied:
What can it be used for?
With the “plume method”, it is possible to determine the extent of the odour plume from a facility under specific meteorological conditions.
With a suitable training, assessors carrying out field inspections may provide some information about odour quality and recognize its provenance.
What can it NOT be used for?
It can’t give us information about odour concentration.
