Olfactory Characterisation of Odours for Optimising Impact Assessment. The repeated release of obnoxious odours from intensive livestock, waste management and wastewater treatment facilities can constitute a major air quality problem for a local population. Odour management has traditionally been maintained by the use of buffer distances that have significantly decreased with urban encroachment.

The repeated release of obnoxious odours from intensive livestock, waste management and wastewater treatment facilities can constitute a major air quality problem for a local population. Odour management has traditionally been maintained by the use of buffer distances that have significantly decreased with urban encroachment. Odour assessment is conventionally measured in terms of odour concentration; however this standardised method does not take into account odour quality characters or their intensity. The project will characterise by sensory means the odour nuisance types and intensity of different odorous emissions to better define and understand the relationship between process operations and olfactory annoyance.Read moreRead less
