42 003    In the Flemish legislation, no odour assessment framework is implemented, despite that odour-related permit applications require the inclusion of an odour impact study. For livestock farming, odour emission factors, derived from olfactometric measurements (ouE), are widely used. Contrastingly, the available assessment tools, based on earlier odour impact research, utilize sniffing measurements (se).

   To allow comparison between the two units of odour, it is assumed that 1 ouE equals 1 se. For most groups of livestock animals with a rather constant growth cycle (e.g. pigs), this comparison is deemed valid and suitable for evaluating the odour impact. However, the theoretical assessment of broiler chicken emissions can be questioned, as the olfactometric emission factor of 0.33 ouE/s.animal results in almost no odour impact.

 

MZacarias   Chile is a country that has different industrial activities generating annoying odors for the communities that live in the surroundings. It seeks to determine the area of impact caused by odors, for which measurements are made with suitable panelists (according to the established in the chilean normative NCh3190: 2010).

   To determine the area of impact, plume measurements are made in accordance to VDI 3940 part 2. On the other hand, the mathematical model of atmospheric dispersion CALPUFF fed with emissions measured by dynamic olfactometry is applied.

For the plant responsible of the odour emission, for the people that is exposed to environmental odours and for the authorities responsible of mantaining an adequate vital and equilibrated ambient air at work. 

   Odour perception is personal, subjective and volatile. Among the many important factors involved in the odour perception, memory plays a key role. Many times, citizens will complaint that their annoyance is not being taken seriously and there is a lack of understanding, and sometimes knowledge, of what happened in the past. Therefore, a successful process of odour management requires both a wide set of relevant information about the odour and an effective comunication strategy among the parties involved.
