An investigation of posible growth environments for mould in the early sawmill handling of oak (English)
Abstract [sv]

Trä är ett biologiskt och organiskt material vars egenskaper möjliggör att det vid rätt förhållanden kan växa mögel på det. Mögeltillväxt på trä som människor hanterar och har i sin närhet kan skapa hälsoproblem då vissa mögelarter kan orsaka respiratoriska problem samt allergisk alveolit.En undersökning av vilken mögelsvamp som växer på brädor vid ett sågverk i södra Sverige har utförts. Utöver detta har möjliga tillväxtmiljöer för mögel undersökts under brädgårdstorkning samt en torkprocess. De undersökta parametrarna var temperatur och relativ luftfuktighet.Mögelsvampen Paecilomyces hittades samt Aspergillus niger och jäst. Klimatet under brädgårdstorkning samt torkprocessen visade att de under stor del av den tidiga hanteringen av virket fanns ett klimat gynnsamt för mögeltillväxt.

Abstract [en]

Wood is a biological and organic material whose properties makes it possible for mold to grow on it under the right conditions. Mold growth on wood that humans handle and get in contact with can create health problems as some mold species can cause respiratory problems and allergic alveolitis.An investigation of which mold that grows on boards at a sawmill in southern Sweden has ben carried out. In addition to this, possible growth environments for mold have been investigated during lumber yard drying and a kiln drying process. The parameters examined were temperature and relative humidity.Mold of Paecilomyces, Aspergillus niger and yeast was found on boards. The climate during lumber yard drying and the kiln drying process showed that a large part of the early handling of the wood had a favourable climate to mold growth.
