Assessing acceptable odour levels

Authors: A. La, Q. Zhang, J. Allston and Z. Gao
Description: The objective of the project was to conduct a survey to quantify the level of odour annoyance of individuals living in the vicinity of hog operations. A set of questionnaires was designed to obtain unbiased responses from residents living in the community. In the initial phase of the study, a site (community) was selected for surveying with the criteria that it must have a sufficient population living widespread nearby to a hog facility. Most households indicated odours from the hog facility and manure storage as the source of the odour. Households further away from the hog facility were more likely to identify other odour unrelated to hog odours as the odour source. Odours related to hog production are prevalent in the upper ranges of the odour annoyance levels, while non-hog related odour sources are limited to the lower odour annoyance levels. Evaluation of the relationship between graphical and verbal odour annoyance scales indicated that the scales were strongly correlated. Odour affected the frequencies of having disrupted enjoyment of outdoors and being forced to close household windows. Further surveying is required for sufficient data to make any definitive conclusions about odour tolerability and odour acceptability.
