N2 - The presence of VOCs (Volatile Organic Compounds) in the indoor
air may be a contributory cause of complaints about irritation of
mucous membranes in eyes, nose and throat, difficulty in
breathing, frequent airway inflammation, skin irritation, fatigue,
concentration difficulty, dizziness and headache. The purpose of
this Ph.D. work was to study the sorption properties of building
products with reference to the selection of building products for
construction and renovation of buildings.In order to provide the
necessary experimental data, a main purpose of the work was to
study the influence on sorption equilibrium and kinetics of
temperature, relative humidity, VOC concentrations and air
velocity past the surface of the building product. Four common
building materials were carefully selected for the
sorption/desorption experiments: Painted gypsum board, lacquered
beechwood parquet, PVC flooring and nylon carpeting with latex
backing.Building product samples were placed in Climpaq chambers
and in a full scale chamber, where they during the
sorption/desorption experiments were exposed at different
conditions to a humid air stream containing 17 common indoor VOCs
. Chemical analyses and sensory evaluations were carried out using
gas chromatography/flame ionisation detection and a naive panel of
32-36 persons, respectively. Individual and total VOC
concentrations were representative of indoor air. Relative
humidity was 45-70%.The VOCs selected for experiments were:
1,1,1-trichloroethane, 2-pentanone, toluene, tetrachloroethene,
n-octane, hexanal, n-pentanol, o-xylene, 2-heptanone,
2-butoxyethanol, octanal, 1,4-dichlorobenzene, limonene,
2-ethylhexan-1-ol, 1,2-propanediol, n-decane and decanal. The work
was performed in collaboration with the Danish Building Research
Institute.Contents: Danish summary (6 pages). Detailed summary in
English (15 pages). Background (23 pages). Objective and
hypotheses (2 pages). Methods and materials (20 pages). Results
(26 pages). Discussion (12 pages). Conclusion (3 pages).
References (14 pages). Appendices (95 pages).
