Abstract

  The management of odours caused by industrial emissions requires standarized and technically-proved methodologies for a correct diagnosis, allowing to assess the problem objectively and, therefore, for proposing the best solutions from an economical and technical point of view. Among the methodologies for odour diagnosis, the emission studies (based on NCh3190 / EN13725) and immission studies (based on VDI3940), are the most used. These methods can be complemented by chemical studies in order to select the best odour control/abatement technology. Depending on the application, there are several posibilities: biofiltration, scrubbing, oxidation (thermal and catalytic), adsorption, etc. In this work, a new methodology for diagnosis and control of odours, is proposed. Odocity-Map is a web supported software that allows to register objectively, the complaints of a panel of city residents caused by odours. This software is based on the German Standards VDI3883 (Part I and II), and allows to take a "photography" of the city nuisance-map and its possible causes. In this work, a Spanish city located in the Mediterranean coast with an important industrial area, is studied. The participation of residents of different city areas, and the frequency of winds during the project, showed the influence of the industrial emissions in the city.

Psychometry

on .

 Psychometry is a very efficient tool in many cases to deal with the problem of odours in a community. The psychometry is the evaluation of the odour complaints distribution by mean of questionnaires given to the people of neighbouring areas. The statistical analysis of the answers given by the neighbours is an starting point and it can help to design a campaign to measure odours by any other method.

The psychometry can give us answers such as:

  • The time-intervals when there is a maximum of complaints.
  • The location of the most problematic areas.
  • The possible source of the odours.
  • The odours with a less accepted hedonic tone by the community..

  The psychometric evaluation is a very effective tool, widely used in many countries (R. Cervinka et al., 2004, E. Gallmann et al., 2004). In Germany there is a norm that specially deals with the psychometric assessment, this is the VDI 3883.

  The Psychometric analysis is quite convenient as a screening study when the purpose is to measure odours by any other method such as field inspections, field olfactometry or dynamic olfactometry + dispersion model, however, this step is often forgotten in many odour studies.

 

Notes:

In New Zealand there is a very interesting norm based on a Psychometric analysis. + info there
