Abstract

   Chile is a country that has different industrial activities generating annoying odors for the communities that live in the surroundings. It seeks to determine the area of impact caused by odors, for which measurements are made with suitable panelists (according to the established in the chilean normative NCh3190: 2010). To determine the area of impact, plume measurements are made in accordance to VDI 3940 part 2. On the other hand, the mathematical model of atmospheric dispersion CALPUFF fed with emissions measured by dynamic olfactometry is applied.

   After performing the odor evaluations, it was possible to group the evaluations according to the prevailing direction of the wind. Subsequently the respective plumes were drawn, taking into consideration the criteria established in VDI 3940, i.e. that for an individual measurement performed by a panelist to be within the plume should exceed 10% in Odor Perception Frequency and otherwise the individual measurement is outside the contour of the plume. After plotting the plumes was preceded to compare the results with those obtained from the dispersion model.

   From the comparisons made, it can be observed that the plumes traced are similar to the isolines of concentration of odor obtained by mathematical modeling.
