Predicted and measured odor levels around a meat rendering plant were compared in two different experiments. Predictions were made by using Calpuff dispersion model. The product of olfactometrically measured odor concentrations and corresponding volumetric flow rates of the stack gases were used as emission strength and used as the input of the model runs. All odor measurements were made by using olfactometry. Olfactometric odor measurements are not frequent in ambient air studies, but it was possible in this study as the concentrations were well above the minimum odor levels of 10 odor units per cubic meter (OU m(-3)) that can be safely measured by this technique.
