The chimpanzees live in groups of 14 individuals with access to environmentally enriched outdoor (770 m) as well as indoor compounds.
In contrast, acetic acid seems to be a more aggressive indoor organic compound for a larger range of objects.
The results of this study demonstrate the feasibility and sensitivity of the exposure system for testing inflammatory cellular effects of indoor gaseous compounds at environmental doses directly on human respiratory cells.
Therefore, it has been suggested that toxic effect estimates of indoor volatile compounds should be adjusted for long-term exposures compared with shorter exposures, at least for nonirritative effects (Damgård-Nielsen et al. 1997).
Experiments and modelling are performed using acetaldehyde which is a common indoor volatile organic compound and titanium dioxide thin film coated on steel performed by a PVD method.
Due to the lack of common EU legislation, the target gases and detection limits have been set after reviewing the literature and the recommendations of different agencies in Europe and the US, focusing on indoor Volatile Organic Compounds (VOCs).
Exposure to indoor volatile organic compounds may be a trigger for asthma; formaldehyde exposure, for example, has a positive association.
All subjects lived in social groups of various sizes in indoor and outdoor compounds.
For other compounds, indoor concentrations were similar, except at the maxima, where Richmond levels were almost always highest.
Associations between asthma exacerbation and both particles and indoor volatile organic compounds (VOCs), often referred to as indoor air quality, have been reported.
