Immunogold labelling of size marker proteins in brown rot-degraded pine wood
1990 - IRG/WP 1428
Pine wood degraded by Fomitopsis pinicola was infiltrated with a mixture of ovalbumin (45 kDa) and myoglobin (16.7 kDa). After crosslinking of the proteins with glutaraldehyde and preparation for electron microscopy ultrathin sections were labeled with gold-conjugated antibodies. Simultaneous labeling of both proteins on the same section showed that at 50-70% weight loss ovalbumin did not penetrat...

A deflection test for monitoring decay in miniature beams
1986 - IRG/WP 2269
A laboratory apparatus for assessing decay in small stakes is described. It involves the measurement of deflection in a static bending apparatus using a displacement transducer linked to a microcomputer. Measurements are non-destructive, rapid, accurate and automatic and decay can be assessed repeatedly over long time periods....

Evaluation by experimentation on site of a new method for termite control
1996 - IRG/WP 96-10173
A new concept of subterranean termite control consists of the installation of toxic baits in or around the infested construction. Dow Elanco has developed a bait system based on Hexaflumuron. This active ingredient is an insect growth regulator with slow acting effect. A lot of trials were conducted in the USA, but none in France until now. We realised on site experiments, in order to estimate the...

A novel lipid-related compound, (Z)-1,7-nonadecadiene-2,3-dicarboxylic acid, produced by white-rot fungus Ceriporiopsis subvermispora
2001 - IRG/WP 01-10411
Lipid peroxidation is a possible oxidative process of lignin-degradation at a site far from the enzymes by selective white rot fungi. Production and peroxidation of saturated and unsaturated fatty acids by Ceriporiopsis subvermispora strongly suggests involvement of lipid peroxidation in its ligninolytic system. In this paper, a new aliphatic lipid-related fungal metabolite was isolated from wood ...

Measurement of VOC emissions from curative treated wood: A new emission test chamber
2001 - IRG/WP 01-50166-13
A poor indoor air quality (IAQ) is now recognized as a potential factor affecting occupants health. There are three basic strategies to improve IAQ: source control, improvement of the ventilation and use of air cleaners. Usually, the most efficient way to improve IAQ is to eliminate the different pollutant sources or to reduce their emissions. In order to precisely measure emissions from building ...

Health and safety aspects of the use of wood preservatives. Preliminary evaluation of the answers to the IRG-Questionnaire on the state of pollution control in the field of wood preservation
1974 - IRG/WP 56
This preliminary evaluation of the answers to the IRG/WP-Questionnaire only gives a general survey on those questionnaires, which the author received until June 13, 1974. Details, such as correlations between importance of wood preservation and pollution control, could not be considered due to lack of time. For the same reason it was not possible so far, to evaluate the additional remarks given in...

Chemical analysis of TnBTO in lap-joints
1999 - IRG/WP 99-20173
This research was performed as part of the EU project FACT (contract SMT4-CT96-2135) on field tests out of ground contact and ageing methods. The results reported here are part of the work on the experimental lap-joint standard (ENV 12037). TNO investigated the TBTO content of 32 lap-joints by analysing the tin content of 90 samples. The lap-joints were treated with two different TBTO-concentratio...

Spatial arrangement of lignin peroxidase in pine decayed by Phanerochaete chrysosporium and Fomitopsis pinicola
1988 - IRG/WP 1343
By applying immunoelectronmicroscopic methods, lignin peroxidase of the white rot fungus Phanerochaete chrysosporium has been localized in the cytoplasm of hyphae, close to the plasmalemma and on the plasmalemma. Infiltration of wood specimen with culture filtrates, concentrated 300-fold, gave clear information on the penetration of the enzyme into the wood cell wall. Penetration was restricted to...

Oxalic acid production of fifteen brown-rot fungi in copper citrate- treated southern yellow pine
2001 - IRG/WP 01-10388
Non-arsenical copper-based wood preservatives have grown in number since the 1980's as a response to environmental concerns posed by arsenicals. Interest in copper tolerant decay fungi has increased accordingly. Oxalic acid (OA) production by brown-rot fungi has been proposed as one mechanism of copper tolerance. Fifteen brown-rot fungi representing the genera Postia, Wolfiporia, Serpula,...

Environmental risk assessment of preservative treated wood
1998 - IRG/WP 98-50101-19
This paper reviews the status of the environmental risk assessment of preservative treated wood and confirms the distinction between the risks presented by wood preservatives and preservative treated wood. The paper proposes a tiered approach to risk assessment and discusses the rationale. Flowcharts are presented which summarise the tiered approach to risk assessment, show the tests required, and...

Differential behaviour of wood rotters at water repellent Rubberwood
2000 - IRG/WP 00-10386
Rubberwood samples treated with different concentration of aqueous solution of chromic acid has induced significant increase in water repellency and attains dimensional stability. Though water repellency and dimensional stability was achieved by treatment, the fungal invasion could not be completely controlled. Differential level of decay of brown and white rot in wood treated with water repellent...

How to determine what is a realistic emission from treated wood - basic reflections
1998 - IRG/WP 98-50105
Emissions from treated wood occur by evaporation and by leaching. Up to date by far more experience exists on leaching tests than on evaporation test. The methods applied will be of interest to give answers to the questions about the quantity of possible emissions. Standardisation on leaching started very early. One of the first attempts to quantify the effect of leaching on the remaining efficacy...

Co-operative research project on L-joint testing. Progress report to May 1989
1989 - IRG/WP 2338
Further sets of data received from STU (Sweden) after 36 months exposure and Sipad-IRC (Yugoslavia) after 45 months exposure are presented and discussed in conjunction with data reported previously. The new data are generally in agreement with those presented previously and the major difference between institutes continues to be one of rate of colonisation rather than any relative difference in pe...

A natural exposure weathering test for the evaluation of preservative performance
1992 - IRG/WP 92-2400
Natural exposure weathering tests were carried out by externally exposing treated wood samples for varying periodes of time up to 36 months. In the laboratory these samples were assayed for residual preservative effeciveness using Coniophora puteana FPRL 11E. The results indicated a loss in efficacy over and above that determined using artificial ageing procedures such as EN73 (evaporative ageing)...

Antagonistic effect of Trichoderma spp. against Serpula lacrymans in the soil treatment test
1991 - IRG/WP 1473
Soil treatment tests for preventing growth of Serpula lacrymans were conducted using Trichoderma spp. as antagonists. Soil specimens tested were Kanuma-soil without organic matter and the horticultural soil which was collected from the test site of the stake test. Perfect efficacy of treatment with Trichoderma spp. was shown when the horticultural soil without sterilization was used as a soil spec...
