Laboratory investigations about the mobility of some inorganic wood preservatives in soils
1998 - IRG/WP 98-50101-22
Wood preservatives and components of wood preservatives leached from impregnated wood can enter the soil and thus contribute to the pollution of the groundwater. However, there is lack of understanding concerning the interacting parameters of wood preservative, leachate, soil and soil solution. To characterise of the behaviour of active ingredients and for the assessment of their environmental imp...

Biodegradation of creosote/naphthalene-treated wood in the marine environment
1977 - IRG/WP 428
The present study was undertaken to determine the biodegradability of marine grade creosote and selected components, including naphtalene, and to determine the effectiveness of (up to 40%) creosote in protecting wood from microbial attack. Also, the impact(s) of creosote and naphtalene-enriched creosote on the microbial ecology os estuarine environments was examined....

Chlorodioxins in pentachlorophenol
1975 - IRG/WP 346 E
At the 6th meeting of the IRG/WP plenary group held on 20 June, 1974, in Vienna, Mr Richardson expressed some concern about dioxins which might be contained as impurities in pentachlorophenol and in sodium pentachlorophenoxide or which might be formed during the combustion of treated wood. He mentioned the malformations that have been noted in Vietnam due to the teratogenic action of the 2, 3, 7, ...

Migration of active ingredients from treated timber into fresh water
1991 - IRG/WP 3669
Spruce roundwoods and segments were treated with three different wood preservatives. Two of them containing copper and chromium the other one free of chromium. After fixation (3 weeks, 20°C) the specimens were leached by using artifical rain or by shaking the segments for one hour in contact with demineralized water. The water was analysed for the relevant elements of the preservative tested. Lea...

Experimental real building evaluation of termite attack - Effect of the space between the mat foundation and the thermal insulation
2000 - IRG/WP 00-10374
For evaluating the termite resistance of the real house foundation, specially in the case of thermal insulation systems for foundation walls, thermal insulation which can be attacked by termite, must be evaluate. Because of the difficulty of the water penetration of thermal insulation, the water barrier systems can be protected against termite attacks, in our opinions. The observation on the proce...

Status of the Working Group on Preservation of Wood in the Marine Environment - Questionnaire results
1977 - IRG/WP 434
At the joint meeting of the IRG and COIPM dealing with preservation of wood in the marine environment, it was suggested that a Marine Group should be formally recognised within IRG. It was agreed that a questionnaire (Document No: IRG/WP/424) should be circulated to determine the views of the membership on the future status of this group. The results of this questionnaire are presented....

An introduction to environmental aspects of groundwater arsenic and CCA treated wood poles in Bangladesh
1997 - IRG/WP 97-50081
The environment comprises biosphere, lithosphere, atmosphere and hydrosphere. Therefore, environmental science is a multi-disciplinary study, includes life sciences, physical sciences, chemical sciences, geology, geography, meteorology, forestry, agriculture, soil science, hydrology, ecology, public health, engineering etc. Tremendous industrial and mining activities, deforestation and population ...

Proposal for further work on environmental questions
1988 - IRG/WP 3494
Although very much is known about the environmental and health and safety aspects on various wood preservatives and treated wood knowledge is still lacking on some important issues. Some examples are: - The fate of wood preservatives in the environment, eg by leaching from treated wood and contaminated soil; - How big is the "problem" of pollution, etc from the wood preserving industry in comparis...

Wood preservation and the environment: A Canadian perspective
1990 - IRG/WP 3577
The non-pressure (surface) and pressure treatment of wood impacts on the environment in four ways. These are: through the production of treated wood at sawmills and pressure treating facilities; during the storage of treated wood prior to use; when the pressure treated wood is placed in service; and finally, when the treated product reaches the end of its useful life and must be disposed. By refer...

Safety clearance of wood preservatives in United Kingdom
1977 - IRG/WP 398
In the United Kingdom the principal route of control of pesticides is through the Pesticides Safety Precautions Scheme (PSPS) which is a non-statutory scheme agreed between government ministries and departments (referred to as "Departments") and associations representing the pesticide industries. The scheme formally began in 1957 covering those pesticides and related substances used in agriculture...

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...

Natural durability of some commercial timbers of Sarawak, Malaysia in tropical marine environment
2005 - IRG/WP 05-10561
The abundant supply of timber resources in Sarawak makes timber an ideal choice to be used for marine construction. The natural durability of the main commercial timber species of Sarawak in ground contact is well established but the same is not available for marine environment.
This study was conducted to assess the natural durability of 28 commercial timber species in tropical marine environmen...

A collaborative test to determine the efficacy of poyurethane coatings on wood samples exposed in the marine environment. 1st Interim Report
1988 - IRG/WP 4145
Wood samples coated with elastomeric polyurethane (ca. 50 mils thick) were exposed for up to 2 years in 12 tropical and temperate marine test sites with known teredinid, pholad and/or crustacean infestations. All uncoated control samples were destroyed or partially destroyed. Polyurethane-coated samples were not attacked, the surfaces of the coating were sound and the polyurethane adhered well to ...
