Formaldehyde : Study of indoor air pollution in Austria.
As part of a long-term study of indoor air pollution, formaldehyde concentrations were determined in 792 apartments following complaints by inhabitants.
Measurements were carried out using Draeger tubes as well as the acetyl acetone method.
In 157 apartments, HCHO concentrations of more than 0.1 ppm, exceeding the recommended standard values for indoor air concentrations, were determined.
The concentrations determined tended to decrease over time.
As far as they were caused by furnishings, they were limited to the spaces where these furnishings were installed.
In older-style prefabricated houses with foam-filled particle-board wall systems, concentrations of more than 1.0 ppm were determined.
In spite of legal regulations governing the release of formaldehyde from substances, preparations and products containing formaldehyde which have been in existence in Austria since 1990, this substance must still be considered as a possible factor of indoor pollution in causing feelings of ill-health.
