International co-operation in wood preservation research
1979 - IRG/WP 3145
If one searched the literature, one could find many examples of international co-operation in the field of research in wood preservation. For example, individual workers in different countries in Europe have got together and made replicate tests with both fungi and insects on various preservatives of common interest and their results have been published. Much co-operation has not had its results p...

Non agricultural biocide directive. Practical proposals of implementation in the case where biocides are wood preservatives
1995 - IRG/WP 95-50040-24
This project of non-agricultural biocide directive has currently an extremely wide scope of pre-marketing authorization of substances and preparations used in numerous applications, other than agricultural. Elaborated on the 86/414/EEC model of the phytopharmaceutical product directive, the "NAB" draft directive aims to cover situations as different as plant or wood protection: in the case of plan...

Free radical process controlled by manganese peroxidase and lipid-related metabolites produced by Ceriporiopsis subvermispora
2001 - IRG/WP 01-10412
Ceriporiopsis subvermispora, a specific lignin-degrading fungus produced free unsaturated fatty acids (USFAs) including 9,12-octadecaienoic asid, together with saturated fatty acids (SFAs) at an incipient stage of cultivation on wood meal cultures. In prolonged cultivation period after two weeks, the amount of intact fatty acids decreased with increasing in organic hydroperoxide and TBARS producti...

1999 - IRG/WP 99-10301
In previous studies, the white-rot fungus Bjerkandera sp. strain BOS55 was shown to cause extensive degradation of lipophilic extractives (resin) in Scots pine wood. Further research was carried out in order to investigate the ability of Bjerkandera sp. for reducing resinous constituents in various softwood (Douglas fir, larch and spruce) and hardwood species (birch, beech and poplar). The greates...

Present status of using treated wood and private house owner’s expectations in Bangladesh
2004 - IRG/WP 04-30329
In a developing country like Bangladesh more than 80 % of the total population lives in rural areas where building materials are mainly comprised of wood, bamboo, thatch grass, golpata, etc. All these materials, being cellulosic, are easily infected by deteriorating agencies like fungi, termites, beetles etc., as climatic condition of the country is ideal for their thrive. This is a great wastage ...

Preliminary Studies on ZiBOC- A Potential Eco-friendly Wood Preservative
2005 - IRG/WP 05-30372
Over the past decade, the wood processing industry has been increasingly involved in strategies to minimize the environmental impacts of treated wood. One sign of this is the dramatic increase in the use of preservatives based on inorganic metal oxides, which fix in wood. Among such preservatives the most common is chromated-copper-arsenate. In Ascu chromium and arsenic both are carcinogenic thus...

The future for chromium in wood preservation
1985 - IRG/WP 3332
Most water-borne preservatives contain CrVI compounds, originally to reduce corrosion although now also to improve toxicant fixation. Chromium contributes to preservation and this is recognised in, for example, New Zealand and USA where chromium contents are included in calculations of overall preservative activity of CCA formulations, but chromium may also have anti-stain and joinery (millwork) p...

The risk assessment process. Point of view of a biocide manufacturer [Évaluation du risque. Point de vue d'un fabricant de biocide]
1990 - IRG/WP 3568
Risk assessment is an inherent part of our everyday lives. The risk assessment equation combines Hazards and Exposure. For the Wood Preservation Industry, the hazards may be characterised by the toxicity a the ecotoxicity of chemicals and the exposure by the identification of exposed people, of the exposure routes and exposure frequency. To quantify the exposure, good co-operation is required betw...

Electrodialytic remediation of a soil from a wood preservation industry polluted by CCA
1998 - IRG/WP 98-50101-14
Soil contamination is often found at wood preservation sites due to spills, dripping of excess preservatives and deposition of sludge associated with dissolved salts of copper, chromium and arsenic (CCA). The electrodialytic process is a promising heavy metal soil remediation technique. It is based on a combination of the electrokinetic movement of ions in soil with the principle of electrodialysi...

Potential use of an emulsified tar oil fraction as a wood preservative: Preliminary technological and environmental assessment
1994 - IRG/WP 94-50028
In order to meet the recent environmental concern specifications of creosote are altered, the B[a]P content is limited and restrictions on the emission of volatile organic compounds (VOC) and higher polyaromatic hydrocarbons (PAH) are expected in some countries. Research has been conducted on an emulsion of a selected tar oil fraction. Using a waterborne formulation opens new perspectives for targ...

Bethoguard; A new wood protecting fungicide for use in metal free ground contact wood preservatives
2002 - IRG/WP 02-30301
Research has identified the limitations in both the spectrum of activity and permanence of organic biocides placed in wood in high hazard environments, particularly in the absence of heavy metals such as copper. More specifically, the control of soft rot decay in wood in soil contact has proven to be most problematic.
The new organic biocide, Bethoguard; an oxathiazine, has demonstrated excellen...

Wood preservation in Canada - Regulation and Registration
2001 - IRG/WP 01-50166-02
The Canadian wood preservation industry is at a critical juncture now as a number of initiatives converge on the industry over the next few years. Issues facing the industry include: Re-evaluation of the conventional wood preservative chemicals - inorganic arsenicals, creosote and pentachlorophenol targeted for July 2001. Delayed registration of new actives as a result of re-evaluation activity an...

Creosote for wood preservation. (Reissued from earlier OECD draft)
1970 - IRG/WP III 1A
The literature on this subject is extensive and, to some extent, repetitive so that for pratical reference purposes it is essential that selective surveys and bibliographies be prepared. Many of these exist and, as an example, the reports issued by The Coal Tar Research Association (Numbers 0156, 0292 and 0396) may be quoted. The following bibliography, listing the more important sources of inform...

Evaluation of hydroxamates as wood preservatives
2004 - IRG/WP 04-30330
Fungicidal activity of different hydroxamates was investigated by laboratory malt-agar block tests to evaluate their potential as wood preservatives. Results obtained indicate that benzohydroxamic acids substituted or not on the aromatic nuclei were unable to protect wood blocks against the white rot fungus Coriolus versicolor while 2-hydroxypyridine-N-oxide (2-HPNO) possesses an interesting activ...

Preservation of basidiomycete hyphae in ancient waterlogged wood materials
1992 - IRG/WP 92-1536
Studies on waterlogged archaeological wood show that basidiomycete hyphae may persist as long as 800 years. In two pine wood samples with Phellinus pini heartrot, one from the foremast of the ship Vasa and the other from a bulwark constructed in the first part of the 12th century, numerous resin covered hyphae were observed. Hyphae with clamp connections that were associated with brown and white r...

What is OECD doing to promote harmonization of biocide regulations
1999 - IRG/WP 99-20182
OECD began work on biocides in 1997 to help Member countries co-operate in the assessment and registration of these products. The work is a part of OECD's Pesticide Programme, and is co-ordinated by the Biocides Steering Group. The goal is to harmonize regulatory approaches to allow countries to conduct evaluations of biocides more efficiently. More efficient evaluations can advance the p...

A combined method for drying and preserving wood in a single step process
2000 - IRG/WP 00-40183
Based on a convective dryer, this process allows to dry and treat wood blocks with diffusible preservatives in the same time. A boric acid solution (heated to fix the wet temperature of the system) is pumped and introduced in the flow system through a venturi, where the air coming back from the drying cell also arrives. The role of the venturi is to create a dispersion of boric acid solution micro...
