Considérant la complexité d’établir un lien entre la dose et l’effet en matière de nuisance olfactive, et par là la difficulté d’apporter une réponse satisfaisante aux riverains subissant la nuisance, les expériences de terrain rapportent la prépondérance des situations conflictuelles. Ces dernières étant dommageables à la recherche de solution, cet article questionne le potentiel de l’observatoire des odeurs comme méthode, non seulement de caractérisation des émissions olfactives, mais aussi de résolution de conflit. Les objectifs qu’il poursuit classiquement sont mis en regard des écueils relevés par la pratique. La capacité du processus à produire un équilibrage du rapport de force entre les parties prenantes et à fournir une matière première sur laquelle baser des définitions communes ouvre les portes d’une négociation possible. Sans cette dernière, la définition d’un niveau acceptable de la nuisance restera conceptuelle et contestable. [less ▲]

A methodology based on the social participation through the use of resident diaries was applied to evaluate the odour annoyance in the surroundings of an industrial park in Belgium during one year. The studied area covers about 8 km2 and includes13 potential odour emitting facilities. A network of 44 residents was implied in the survey, from which 19 were particularly considered for a detailed analysis. The questionnaire aimed at providing twice-daily an odour strength rating on a 6-level scale together with an odour qualifier. The fact that the response rate corresponding to "no-odour" was high (79%) is particularly discussed. Some tests are proposed to check the plausibility of the responses, the consistency within clusters of residents and the individual performance of respondents to discriminate among odour ratings. The odour rose is presented as an attractive and visual tool, particularly suited in the case of multi-source areas, to map the different odour emissions, to point out the more worrying ones, some others creating less annoyance and possible new unpredicted ones. The resident diary method proves to be very interesting, especially in the case of an industrial area, provided that validation checks are performed to insure the data reliability. [less ▲]

The network involved 44 residents in the survey, among whom 19 were particularly considered for a detailed analysis. The questionnaire aimed at providing an odour rating twice-daily on a 6-level scale together with an odour type. The fact that the response rate corresponding to “no-odour” was high (79%) is particularly discussed. Some tests are proposed to check the plausibility of the answers, the coherence within clusters of residents and the individual performance of respondents to discriminate among odour ratings. The odour rose is presented as an attractive and visual tool, particularly suited in the case of multi-source areas, to map the different odour emissions, to point out the most worrying ones, to identify others creating less annoyance and possibly new unpredicted ones. The resident diary method has proven to be particularly useful, conjointly to other ones, to the case of multi-sources facilities in large areas, when the purpose is the assessment of the long-term evolution of odour annoyance.

The management of grassed buffer strips proved to be an efficient remediation technique in controlling nitrogen losses to surface water. In south Belgium, agri-environmental policies have encouraged farmers to seed buffer strips along rivers, in zones where the soil was previously devoted to agricultural production. We wanted to assess how important denitrification is in a buffer strip in comparison with a cropped field. The study investigated the denitrifiying enzyme activity (DEA) of two contiguous buffer strips with different management stories. The eastern part of the buffer strip was seeded in 1999. The western part of the buffer strip is a piece of crop field abandoned by the farmer 20 years ago and not managed for the last 10 years. This experimental study demonstrates that the denitrification enzyme activity in a riparian buffer strip is significantly higher than in the adjacent cropped field (3.67 and 2.12 mgNkg(-1)d(-1) respectively). The DEA was significantly different between the two buffer strips under comparison, assessing that the management of the buffer strips has a dominant effect on DEA. The old unmown buffer strip is potentially more efficient in the nitrate removal process than the 6-year-old seeded buffer strip. [less ▲]

Riparian buffer strips are managed for the enhancement of water quality through control of non point source pollution. Denitrification in riparian buffer strips is thought to be the major process -with nitrate uptake by plant growth- that reduces nitrate input in surface water. We investigated the Denitrifier Enzyme Activity (DEA) to test how the buffer strip management modifies the denitrification process. The experimental site is composed of a crop field and a 11 m wide grassed buffer strip at the border between the crop field and a tributary to the Attert river, South-East Belgium. Soil samples from the crop field and the buffer strip have been submitted to different imposed conditions combining glucose, nitrate and water saturation to investigate how antecedent water regime, nitrate and carbon content affect denitrification. The work included DEA measurements on undisturbed soil cores freshly sampled. Experiments on undisturbed soil cores identify the buffer strip as more effective in denitrification (p < 0.001) than the cropped field. However, experiments on samples conditioned under imposed carbon and/or nitrate contents emphasised the importance of micro-topography. [less ▲]
