The goal of this project is to determine the odour annoyance-exposure correlation based on which setback distances can be determined. The odour annoyance is assessed by face-to-face interviews of residents living nearby swine operations. The odour exposure is quantified through dispersion modeling. Two dispersion models were used to predict the odour concentrations and frequencies at each household interviewed surrounding the odour source, and the predictions are then converted to odour hours to quantify the odour exposure. It appears that the odour annoyance could be assessed by face-to-face interviews with properly designed questionnaire. The dispersion models could be used to quantify the odour exposure. Although the results presented in this paper was preliminary and only limited data was collected, the plot of percentage of acceptability vs. odour hours predicted by dispersion models represented the trend of annoyance-exposure relationship for hog odour.
