Biofouling and bioresistance of bamboo in marine environment
2003 - IRG/WP 03-10482
Proudly known as “green gold” and popularly called as “poor man’s timber”, bamboo is closely interwoven with the life of scores of people around the globe because of its versatile qualities and desirable strength properties as a structural material. It is used for innumerable purposes both on land and in water including seas and brackishwater bodies. "Presently, bamboos constitute an i...

Rates of emission from CCA-treated wood in the marine environment: measurement, modelling and requirements for further research
2001 - IRG/WP 01-50166-12
Accurate estimates of rates of emission of leachate from preservative treated wood are crucial for realistic predictions of the environmental impact of its use in maritime construction. Estimates are available for some commonly used preservatives, but these vary widely. Though variable, these measurements suggest that emission generally decreases exponentially with time. Part of the variation is d...

Système informatisé d'aide à la décision pour la gestion de la migration du pentachlorophénol dans l'environnement
1993 - IRG/WP 93-50001-10
This paper describes a Decision Support System (DSS), concerning pentachlorophenol (PCP) migration in the environment. The principal objectives of the DSS are to assist managers in siting of PCP-treated poles in the Hydro-Québec system and the storage areas and in the treatment of customer complaints. Four mathematical models are incuded in the system: a model simulating migration inside and on t...

Eco-tax - A new threat for wood preservation? The Belgian experience
1993 - IRG/WP 93-50001-32
At the end of January 1993, a bill was put for Belgian Parliament related to the introduction called "Eco-taxes" on a series of products, such as packaging for drinks (especially on PVC-bottles), non-returnable articles (shavers, small cameras), batteries, pesticides for non-agricultural use and paper....

Assessment of losses of wood preservatives from treated wood by leaching into the environment
1993 - IRG/WP 93-50001-13
Wood preservative chemicals may be lost from treated timber by leaching into water or soil. The degree to which this might occur and its effect on the environment is difficult to assess quantitatively due to the absence of appropriate test methods. This paper describes work to assess test methodology capable of allowing the rates of loss of wood preservative from treated timber to be quantified. T...

Information from the COIPM Wood Group. Summary received via Mme Dr Anna Gambetta (Italy)
1987 - IRG/WP 4139
Two co-operative programmes were discussed: 1) The IRG/COIPM co-operative programme on the CCA/CCB wood treatments and 2) The IRG/COIPM co-operative programme for testing the resistance of plastic wrapping for wooden pilings. The following was reported: In the wood treatment programme, beech, pine and alstonia wood samples have been pressure treated with 3 retentions (3%, 6% and 10%) of CCA and CC...

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...

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...

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...
