ORM (OPTIMAL REMOVING OF MOISTURE FROM WATER DAMAGED BUILDING CONSTRUCTIONS) - MVOCS

摘要

The Norwegian ORM project was focussed on establishing optimal procedures for removing moisture from damaged constructions with as low possibility for microbiological activity as possible. Different floor coverings were water damaged and contaminated with a mixture of spores and then dried in different ways. During the drying process, the emissions of MVOCs were measured and the moulds were studied. In this paper, results of the measurements of MVOC-emissions from a parquet sample dried in a natural way, are presented. The measurements showed different emission profiles during the 85 days drying process for volatile and semi-volatile MVOC-compounds. The emission of semi-volatile MVOCs was detectable for much longer periods than the emission of volatile compounds. The results of the study show that MVOC-investigations can be used as a non-destructive way to indicate the presence of active moulds inside building constructions and thus help the practitioners to choose the best remediation strategy.
