Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOC) were con-
centrated by adsorbing them to Tenax. After three days, the VOCs were isolated by gas chro-
matography following thermodesorption with cryofocussing. The VOCs were then identified us-
ing mass spectrometry. The individual substances were either quantified against an external tol-
uene standard or quantified substance-specifically by mass spectrometry.
Evaluation base: The evaluation is performed according to the require-
ments of the AgBB (Committee for the Health Assessment of Building Prod-
ucts in Germany). It was founded in 1997 by the state workgroup “Um-
weltbezogener Gesundheitsschutz” (LAUG, Environmental Health Protec-
tion) of the “Arbeitsgemeinschaft der Obersten Landesgesundheits-
behörden” (AOLG, Working Group of the Upper State Health Authorities).
The AgBB requirements constitute a regularly updated approach for the health assessment of
VOC emissions from building products used on the interior of buildings.
Volatile organic compounds according to these requirements include compounds in the reten-
tion range from C
6
to C
16
, which are examined as individual substances and sum parameters
under the TVOC concept (Total Volatile Organic Compounds), as well as semi-volatile organic
compounds (SVOC) in the retention range from C
16
to C
22
. The cumulative SVOC value indicates
the sum of all individual substances with a detection limit of 5 μg/m³. A detection limit of 1 μg/m³
is applied for all other individual substances.
All CMR substances (carcinogenic, mutagenic, toxic to reproduction/fertility) according to the
Ordinance on Hazardous Substances are not included. These always to be considered as a cri-
terion for exclusion.
The quantification of the identified substances with NIK and CMR values is performed by sub-
stance. The quantification of the identified substances without NIK values and the unknown sub-
stances is respectively performed against toluol equivalents.
