“…This was carried out by IPSN at the "Étang de Berre" [9], the Estuary of the Seine [10], the North coast and the Rhine [11]. In practice, this may be carried out upon request by an administration that wants to orient an approach for the odour control of certain of its industrial sites.…”

Olfactometry or measurement of odours by sensory analysis is used to quantify odours. The available methods are used to measure three variables: odour concentration, odour intensity and odour annoyance. The first two variables are measured by a panel of pre-selected experts and the third relies on a local population panel. Measurement of these three variables can characterise the different odour sources of a site and compare them; it can also characterise the environment of the source of odour.Article available at http://analusis.edpsciences.org or http://dx.doi.org/10. 1051/analusis:2000280188 -the first consists in correctly classifying, by order of odour intensity (see later), solutions of butan-1-ol or pyridine in water; the concentrations of these solutions are evenly distributed in a series from 1 to 1000;-the assessors are then qualified according to their individual perception threshold (see later) for five pure chemical compound (butan-1-ol, hexan-2-one, pyridine, propionic acid and tetrahydrothiophene); for each of these compounds, the individual perception threshold of the assessors should fall within a range of 0.1 to 10 times the perception threshold provided as a reference. That confirms that the aim of the selection is not to keep the most sensitive assessors. This qualification is verified on a regular basis.For the analysis of a gas sample, the operator chooses as far as possible panel members with demonstrated individual perception thresholds that are dispersed in a homogenous manner. The representativeness of the population sample formed by the panel depends directly on the number of the members: the higher is the number of panel members, the more reproducible and reliable is the measurement. Therefore, a compromise has to be reached between the cost and the validity of the results. At least 16 panel members is recommended if a good precision on the measurement result is required, 6 to 8 panel members in most cases and 4 panel members for comparative measurements. SamplingThe sampling of odorants is an important part in measuring the odour. It conditions the quality and reliability of the results of the measurement. In France, standard NF X 43-104 [3] describes different gas sampling procedures according to the type of source and analysis, as well as the conditions for the storage and the transport of the samples. The methods described in this standard include odorous atmospheres and then apply to olfactometric analysis (sensory analysis) as to physico-chemical analysis.The sources of odour can be release from stack (channelled sources), surface of a liquid, semi-liquid or solid material (diffuse sources such as lagoons, basins in sewage treatment plants, etc.) or the whole of a building with all of its openings when the release are not channelled.In the case of channelled sources or buildings with openings, the sampling probe is introduced in the gas studied that means in the release stack or directly in the ambient air of the building.In the case of diffuse sources, whether or not artific...

“…Para a determinação da percepção ambiental da população que reside na região rural da bacia hidrográfica do Rio Fragosos, foi aplicado um questionário, preenchido através de entrevistas, adaptando-se aos modelos propostos na norma VDI 3883 (1993), Perrin et al, (1994) e pela Comissão Internacional de Engenharia Rural (CGIR, 1994).…”

A bacia hidrográfica de Rio Fragosos, no oeste catarinense e a bacia hidrográfica do Rio Cachoeirinhas, no sul de Santa Catarina foram unidades pilotos para a aplicação de duas metodologias para avaliações de odores provenientes da suinocultura. Na bacia do Rio Fragosos ficou destacado para a grande maioria das pessoas situações de ambiente desagradável, muito desagradável e extremamente desagradável. As concentrações dos odores obtidos na bacia do Rio Cachoeirinhas, determinadas a montante e a jusante de uma propriedade piloto, no interior de uma granja de criação de animais, sobre uma unidade de armazenamento de seus dejetos e na residência de um produtor variaram de 257 UO/m 3 à 963 UO/m 3 . Estas concentrações indicaram intensidades de odores com níveis forte a muito forte. ABSTRACTThe 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/m 3 to 963 OU/m 3 . These concentrations indicate odor intensities with strong and very strong levels.

RésuméAIR NORMAND, observatoire de la qualité de l'air en Haute-Normandie, est régulièrement sollicité pour des problèmes d'odeurs. La métrologie classique s'avérant peu adaptée, il est fait appel aux habitants eux-mêmes pour analyser, après apprentissage, les odeurs avec leur nez. En parallèle et avec la même méthode, des experts sillonnent les sites industriels pour inventorier les différentes odeurs.Il en résulte une meilleure connaissance des odeurs et l'instauration d'un dialogue entre les émetteurs et les populations riveraines. Le but ultime reste de mesurer objectivement une diminution des odeurs, après la mise en place de moyens d'abattement. Des résultats en ce sens ont déjà été atteints, un encouragement pour d'autres démarches prometteuses. AbstractAIR NORMAND, air pollution monitoring network in Haute-Normandie, is regularly requested for smell problems. Owing to the lack of efficient devices, voluntary residents learn to recognize smells (quality and force). In the same time and with the same method, experts make an inventory of whole smells met inside industrial sites.Thus, the knowledge of this subject is increasing and a dialogue can be set up. The main aim consists in measuring smell decrease with objectivity, after leading programs to cope with them. Good results have already been achieved, others are expected.
