Odour assessment methods: appropriate uses to obtain the most accurate results

This paper presents a brief summary of the different methods for assessing odours and discusses their advantages and disadvantages. Odour assessment methods are divided into two categories: assessments at potential sources and ambient assessments at affected areas, which are usually residential areas located close to potential odour sources. Despite there being several available methodologies, the emphasis is on the following methods: source odour testing with dynamic olfactometry evaluations and dispersion modelling analysis to predict off-site odour concentrations; ambient sampling with dynamic olfactometry analysis, monitoring of ambient odour concentrations using the Nasal Ranger and the Scentroid SM100. In addition to the brief summaries of each available methodology, seven case studies are also introduced to compare their results when different techniques are used
