Untersuchungen unterschiedlicher Baumaterialien auf das Vorkommen von Schimmelpilzen und deren Mykotoxinen

Abstract

In 1997, large areas in South Poland were affected by a flood of the River Oder. As a immediate measure to support shelterless people living in these areas, simple pavillons were built, which two years later had to be evacuated because of high contamination with moulds. The rate of mould contamination on the walls in interior microclimate and the occurrence of OTA was estimated in two of these pavillions. The air-flow and the moisture were regulated in the experimental rooms where wallpaper was used as the research material. The gypsum cardboards on the walls were also observed. It was found that the moulds were of different species and the number of them was constantly changing irrespective of the accepted configuration of the research position. In every single wallpaper sample OTA was detected. The greatest amount of OTA was found in the pavillions with humidified air. The test of gipsum cardboard walls in pavilions chosen at random, showed an enormous amount of moulds. However, the OTA was not detected.
