EN16841 1  The 26th of February 2015 a CEN enquiry was finally launched on two projects related with the determination of odours. The Working Group 27 of the Technical Comittee 264 of the European Committee for Standardization (CEN) had the task of developing this Standard and looks like the final draft is ready.

   This European Standard will describe two methods for direct assessment of odours in ambient air and will supplement the dynamic olfactometry method described in EN 13725 which is generally only suitable for measurement of odour emissions at the source, as the practical lower detection limit is typically ≥10 ouE/m3 (according to the Final draft) and cannot be applied directly to determine odour exposure in the field.

sesion06 marchant01  Dispersion modeling defines the relationship between the emission source and the receptor. While control measures may be applied to the emission source, compliance with odor nuisance standards depend on whether the odor concentrations at the receptor have been adequately reduced with respect to their frequency, intensity, duration and location.

ProOlor. Prognosis of Odours

proolor software   There is a wide range of methods used to monitor incidents at a real time scale using dispersion models in some occasions coupled with electronic sensor gas emission monitoring. In other cases the monitoring is made with the help of real data from residents or with dedicated panellists. They all have one thing in common: These tools predict the event when it is already happening, therefore there is no option for the plant manager to take actions to correct the incident.
