Laura Capelli. Latest findings in the field of area source sampling.

Laura Capelli Odour Talks   In October 2016 we organized the first Odour Talks. The idea was to select key experts in several fields of odour management and to let them present a work of interest on the subject. To make this experience available to the rest of the world, we did a webcast online of the Talks. Some people subscribed to the webcast sessions and they could do online questions to the speakers. A few months after this experience, we have decided to make the videos available to everyone, so here you have an Odour Talk about the latest findings in the field of area source sampling by Ms Laura Capelli.

   Laura Capelli is assistant professor at the Department of Chemistry, Materials and Chemical Engineering “Giulio Natta” of the Politecnico di Milano, Italy. Her research activity is related to odour science and engineering, focusing especially on odour sampling, development of electronic noses for environmental air quality monitoring, dispersion modelling and characterization of odour emissions from different industrial activities. She has authored more than 100 papers in international journals and conferences.

7 days left. Is your country endorsing the EN 16841?

16841 field inspection2   One week left for the EN 16841 to be implemented at national level by publication of an identical national standard or by endorsement. Just seven days to start working with this new European Standard that describes two methods for direct assessment of odours in ambient air: The grid method and the plume method.

    The dynamic olfactometry method described in EN 13725 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 of the EN 16841). Dynamic Olfactometry should not be applied directly to determine odour exposure in the field, although some authors claim that this is possible.

The odour level: the key parameter to distinguish odorants abatement from odour abatement

Intensity vs. Odour Concentration

   The terminological distinction between the quantities of stimulus and sensory effect is very important and leaves no room for misinterpretation of olfactometric results. The introduction of the odour level as a link between olfactory stimuli and effects will help to reach this objective.
