Introduction
Many economic activities and land uses emit levels of odour to the atmosphere that have the potential to compromise air quality at the local or regional scale. Complaints resulting from the impacts of such emissions are common (Henshaw et al., 2006) and the task of ensuring that development proposals are compatible with neighbouring land-uses is an important and often contentious responsibility for regulatory authorities.
It is common for jurisdictions to assess the odour impact potential of development proposals by comparing model predicted odour exposure statistics at sensitive receptors against jurisdictional exposure limits or criteria. These criteria are typically specified in the form of a single concentration limit, percentile compliance level and averaging time, which act to limit the intensity and frequency of odour impact events that may be experienced at receptors.
