For the prevention of odour annoyance and complaints by residents odour impact criteria
(OIC) are established by responsible authorities, which determine separation distances
between odour sources and residential areas. Separation distances are an ultimate measure for the actual protection level (PIRINGER ET AL. 2013). There are a variety
of national OIC (NOIC), which differ by the odour concentration threshold between 0.1
ou/m3 and 20 ou/m3 and by the tolerated exceedance probability of this threshold
between 0.1% and about 35%. The ambient odour concentration may only be exceeding
this odour concentration threshold for a percentage of hours in the year, which is determined by the exceedance probability (NICELL 2009). These NOIC are specified to
intended protection level such as land use or population densities (PIRINGER ET AL. 2013). These large differences among the NOIC lead to the question if the NOIC for
the same intended protection level determine comparable separation distances.
