or actions for climate protection, precise values are
needed by theoretical estimations or qualitative measurements.
As propagation model, a lagrangian partical model is
used and the concentration measurements were performed
as open-path-measurements in distances up
to over 500 m. According to the measuring results, the
emitted gas will be evaluated by an adapted dispersion
model.
ated. Hence the supplying industries and foundries are
motivated, to solve the upcoming odour problems with
the help of forming auxiliary agents; and to approach
an optimization and a sustainable improvement of
wide scope.
The cooperation of ISWA in this project was mainly related
to the development of the measuring technique,
in order to evaluate the emissions of different forming
auxiliary agents in odour technical aspects. The analytical
procedure for odorous substance detection is
described in detail as follows:
• With variation of adsorption- and desorption-conditions
in thermal desorption procedure, even odorous
substances with lower mass numbers could be
recorded by the analysis.
• Extension of the detector system: with an additional
flame ionization detector, a precise quantification
of odorous relevant compounds could be
achievable. The GC/MS/FID-System, in conjunction
with the Olfactory-Detection-Port (ODP), which is
also called Sniffing-Detector, proved itself useful on
this problem as well as other applications.

Minimization of odour emission in foundry
sections – Part II
In a research project which was completed in 2008,
the basics of olfactory (odour technical) evaluation of
the forming auxiliary agents in foundries was accomplished.
These kinds of forming auxiliary agents, such as adhesives,
feeder heads, refractory dressings and sand
additives, make a great contribution to the odour balance
of moulding in sand form. Quantity and importance
of the odour contribution was defined and evalu-
