Different approaches to measure environmental odours emitted by landfill areas

This paper presents different methods to assess the
odour emission and the odour annoyance in the
surroundings. It is shown, on the example of landfill areas
and composting facilities, that chemical analyses are
helpful to identify key compounds of the odour release,
and to set up the specification of a monitoring instrument.
Sensitive methods, like dynamic olfactometry or sniffing
team investigation, are mainly applicable to provide a
global odour plume or an average annoyance zone. And
the electronic nose can supply a warning signal to the
plant manager or a real time estimation of the annoyance
zone.
