BELLI FILHO, Paulo et al. Evaluation of odor impacts in hydrographic basins with swine production. Eng. Sanit. Ambient. [online]. 2007, vol.12, n.3, pp.252-258. ISSN 1413-4152.

The River Fragosos hydrographic basin in the west of Santa Catarina and the River Cachoeirinhas hydrographic basin in the south of Santa Catarina were the pilot units for the application of two methodologies for the evaluation of odors originating from swine rearing. In From the results obtained for the River Fragosos basin, for the great majority of responses, unpleasant, very unpleasant and extremely unpleasant environmental situations were highlighted. The odor concentrations obtained for the River Cachoeirinhas basin, determined upstream and downstream of a pilot property, inside animal rearing smallholdings, above a waste storage unit and a producer's home, varied from 257 OU/m3to 963 OU/m3. These concentrations indicate odor intensities with strong and very strong levels.

Keywords : Swine; odors; olfactometry; olfactometer; hydrographic basin.
