The aim of this study was to assess the cost of not regulating odour emissions. For that we have specified a domain in the Spanish region of Euskadi situated in the North of Spain. To perform this analysis, two factors have been considered: 1) The decrease in the property value affected by odour impact and 2) The economic impact on public health.

   To assess the cost of depreciation of odour-affected properties, a list of Activities Potentially Generating Odour Impact (APGOIs) was selected in the Basque Country. With this data, buffers were generated for different areas of odour nuisance, classifying them as serious, moderate and slight. Subsequently, the number of properties with the potential to be affected by odour impact was calculated. This analysis took into account the price per m2 of each municipality in Euskadi. The results showed that the total cost of depreciation of the value of the properties affected by odour impact was 778 and 1164 million euros for areas affected by serious and moderate odour impact, respectively.

 

   TodayFirst draft handbook, the over 50 volunteers that are working on the first International Handbook on the Assessment of Odour Exposure by using Dispersion Modelling reached their first milestone. The first draft of this handbook, was just released (only available for the volunteers) and it has, at this stage, 289 pages of information on the topic.

   The group has had already 20 monthly meetings since the very first meeting took place the 27th of August 2020. This development is being led by Ms. Jennifer Barclay, principal scientist of Atmospheric Science Global (ASG) in New Zealand and Dr. Günther Schauberger, professor of the University of Veterinary Medicine of Vienna, Austria.

Gral gui222   The well known Graz Lagrangian particle model (GRAL) system developers, with a free Graphic User Interface (GUI) available in both Linux and Windows, have released the new GRAL and GUI version 22.03 with plenty of bug fixes and new features.

   According to developers, systematic refactoring will improve the prevention of such bugs in the future, as the readability and maintainability of the code has increased significantly.
