Class separation of buildings with high and low prevalence of SBS by principal component analysis

In this study, we were able to separate buildings with high and low prevalence of sick building syndrome (SBS) using principal component analysis. The prevalence of SBS was defined by the presence of at least one typical skin, mucosal and general (headache and fatigue) symptom. Data from the Swedish Office Illness Study describing the presence and level of chemical compounds in outdoor, supply, and room air, respectively, were evaluated together with information about the buildings in six models. When all data were included the most complex model was able to separate 71% of the high prevalence buildings from the low prevalence buildings. The most important variable that separates the high prevalence buildings from the low prevalence buildings was a more frequent occurrence or a higher concentration of compounds with shorter retention time in the high prevalence buildings. Elevated relative humidity in supply and room air and higher levels of total volatile organic compounds in outdoor and supply air were more common in high prevalence buildings. Ten building variables also contributed to the separation of the two classes of low and high prevalence buildings.     

Characterizing Mold Problem Buildings – Concentrations And Flora Of Viable Fungi

The purpose of this study was to characterize mold problem buildings by determining concentrations and flora of viable fungi. The composition and concentrations of fungal flora in mold problem (n = 9) and reference buildings (n = 9) were determined by means of four different sampling methods: six-stage impactor (Andersen sampler), sedimentation plate, surface and house dust samples. Samples were taken in the fall and in the winter, and the concentrations and flora in mold problem buildings were compared with those of matched reference buildings. The differences between mold problem and reference buildings were most clearly seen with the impactor samples. The total concentrations of airborne fungi were higher in moldy buildings. In addition, the concentrations of the genera Aspergillus and Oidiodendron in the fall and the concentrations of Aspergillus and Penicillium in the winter were higher in mold problem than in reference buildings. In the winter, certain fungal genera (Stachybotrys, Acremonium, Oedocephalum and Botryosporium) were detected only in the problem buildings in impactor samples. These results indicate that there may be an unusual composition of fungal flora in mold problem buildings. The results of the sedimentation plate samples showed a trend similar to that of impactor samples in the winter. In addition, the results of surface samples supported the data on the fungal flora in the winter-time air samples. The house dust samples did not reveal any differences between mold problem and matched reference buildings.

A comparative study of VOCs in Singapore and European office buildings

This study compares the characteristics of volatile organic compounds (VOCs) and the associated factors affecting them within European (EU) and Singapore buildings. Generally, concentrations of target VOCs determined in the two types of buildings were within health and comfort guidelines. This study found that concentrations of 2-methylpentane and n-heptane were significantly higher in the EU buildings, while those of n-tetradecane, 2-ethyl 1-hexanol, benzene, toluene, m/p-xylene, benzaldehyde and naphthalene significantly higher in Singapore buildings. Area specific emission rates of the methylpentane isomers, n-heptane and isoprene were significantly higher in the EU buildings, while those of 2-ethyl 1-hexanol, benzene, toluene and naphthalene were significantly higher in Singapore buildings. Lower ventilation rates within Singapore buildings caused relatively higher concentrations of m/p-xylenes and benzaldehyde despite no differences in emission rates between the two types of buildings. Elevated levels of 2-ethyl 1-hexanol in Singapore buildings are due to the higher air velocities and relative humidity indoors. There were no differences in 1,1,1-trichloroethane and 2-propanone levels, suggesting similar use of consumer products and occupant densities relating these two VOCs. Higher emission rates of methylpentane isomers and heptane were associated with the use of adhesives and solvents related to internal surfaces while higher emission rates for isoprene in the EU buildings were associated with environmental tobacco smoke (ETS). Higher levels of benzene, toluene and naphthalene in ETS-free Singapore buildings were associated with human-related activities.
