Degradation of polychlorinated organic biocides by the wood decaying fungi
2008 - IRG/WP 08-50253
Organochlorine biocides such as lindane, pentachlorophenol sodium salt, and polychlorinated biphenyl 153 have been widely used as wood preservatives. Due to their low degradability by soil bacteria, treated waste wood products pose a serious threat to the environment. Consequently, there is an increased need for development of new strategies for their detoxification. In this work, the bioremediati...

Influence of fungal exposure on the redistribution of copper in treated spruce wood
2002 - IRG/WP 02-10450
The redistribution of copper in treated wood after exposure to basidiomycete decay fungi is described. The micro-distribution of copper in copper(II) sulphate or copper(II) octanoate/ethanolamine treated Norway spruce wood before and after exposure to 3 different wood decay fungi was studied using transmission electron microscopy with X-ray microanalysis. The copper content of the mycelium and the...

Influence of ethanolamine on lignin depolymerization and copper leaching from treated Norway spruce and beech wood
2007 - IRG/WP 07-30423
Copper-ethanolamine based wood preservatives are replacing several classical copper-chromium based solutions, due to foreseen ban of chromium. Fixation of copper-ethanolamine based wood preservatives is not as good as fixation of copper-chromium ones. The main object of this manuscript was to prove, that ethanolamine is the prime reason for insufficient fixation of copper-ethanolamine formulations...

Influence of Polyvinyl acetate emulsion (PVA) on boron leaching and fungicidal properties
2008 - IRG/WP 08-30451
Boron compounds are very effective fungicides, but unfortunately they leach from wood. In order to improve boron fixation, boric acid, borax were combined with polyvinyl acetate emulsion (PVA). For comparison copper salts were included into this research as well. Selected preservative solutions were chosen for impregnation of Norway spruce wood specimens (Picea abies). Wood blocks were exposed to ...

Influence addition of boron compounds to adhesives on the bonding quality and fungicidal properties of glued wood
2010 - IRG/WP 10-40497
Wood is one of the most important construction materials. However, users of wood face two issues: limited dimensions and insufficient durability. These issues have been overcome with the development of bonding and wood preservation. The preservation of glued wood is elucidated in this paper. Through the addition of boric acid to adhesives, we tried to improve the fungicidal properties of glued woo...

DuraSoft Project: a multidisciplinary approach for softwood protection
2021 - IRG/WP 21-50367
Over the course of millennia, fishing and agro-pastoral activities have produced unique housing types in the Italian lagoons and in the Slovenian highlands where the use of wood is predominant. They are associated with wooden service infrastructures such as piers, moorings, piling and fences. However, the existence of these structures and the associated cultural heritage are subject to constant ...
