Environmental situation on wood preservation industries in Bangladesh
2000 - IRG/WP 00-50148
The hazard that wood preservative chemicals pose to people and the environment is serious. The lack of information, legislation and awareness create an unfavorable situation on wood preservation industries. In this regard, three wood preservation industries have been visited to collect the information about pollution. It was observed that different steps have been taken to minimize the contaminati...

Kiln drying of CCA-treated wood - Some safety and environmental considerations
1987 - IRG/WP 3443
Vapours and condensate from a condenser kiln in which CCA-treated wood was being dried have been collected and analysed. The concentrations of arsenic, copper and chromium found in the vapours from the drying process were well below Swedish threshold limit values. The contents of arsenic and chromium were also low in the condensate, although the copper content was fairly high. The latter result wa...

Environmental risk assessment of treated timber in service: The Environment Focus Group approach
2000 - IRG/WP 00-50162
In the context of the Biocidal Products Directive (98/8/EC), and of the OECD work on wood preservatives, the Environment Focus Group (EFG), comprising 8 institutes and the European Wood Preservative Manufacturers Group, has been working on the environmental risk assessment of treated timber in service. A literature review of emissions from treated timber has revealed that very little existing data...

Report on the burning of wood treated with wood preservatives containing copper, chromium and arsenic
1976 - IRG/WP 379
Mixtures of copper, chromium and arsenic salts are used extensively in the UK to preserve timber. This report is concerned with the fate of these metals when timber treated with these salts is burned. A large percentage of the arsenic present in the timber is shown to be volatilised during combustion and the potential environmental implications of this are assessed by comparison with the release o...

A collaborative test to determine the efficacy of polyurethane coatings on wood samples in the marine environment. 2nd Interim Report
1990 - IRG/WP 4161
The results of a collaborative international test to evaluate the performance of elastomeric polyurethane coatings of wooden test samples exposed in seawater at 13 sites around the world are reported. The samples have been exposed at sites with known infestations by molluscan and/or crustacean wood borers. Performance data for up to 4 years exposure at some sites is presented providing information...

Termite control in the post-organochlorine era: How do we advise industry and society?
1990 - IRG/WP 1435
Organochlorines have been severely restricted and banned in many States in North America, and replaced by organophosphates and synthetic pyrethroids. This situation may occur in Australia, and elsewhere, in the not too distant future. Just how do we as entomologists advise the industry and society in termite control in the post-organochlorine era? A brief historical overview of pesticide bans and ...

A new method for the study of microbiological decay of wood in a strictly anaerobic environment
1988 - IRG/WP 2319
Recent work has suggested that strictly anaerobic bacteria may play a role in the biodeterioration of wood, particularly in aqueous environments. However, no suitable test methods exist for the investigation of this hypothesis. An aqueous minimal medium in specifically adapted conical flasks was sterilised, gassed using a 5.5% H2; 31.8% C02; 62.7% N2 gas mixture to remove oxygen and transferred to...

The environmental chemistry of chromium: Science vs. U.S. law
1993 - IRG/WP 93-50014
The cooperation which existed among chromium chemical producers, industrial health laboratories, and governmet agencies was destroyed after 1970 by the advent of environmental activism and regulatory legislation. As prewar plants had been found to pose a serious cancer risk, this fact was the basis of EPA regulations, especially during the term of Joe Califano in HEW under Jimmy Carter. However, a...

Effectiveness of CCA fixation to avoid hexavalent chromium leaching
2002 - IRG/WP 02-50187
It is generally assumed that hexavalent chromium in chromated copper arsenate wood preservative is substantially reduced to trivalent chromium during fixation and that the potential to leach the more toxic CrVI is minimal. However, there are occasional claims some hexavalent chromium remains in wood after fixation and that small amounts of CrVI are available for leaching. One problem is that ot...

Evaluating possibilities of leaching of deltamethrin and TCMTB (insecticides and fungicide for protecting wood) by rain water or by soaking in water
1988 - IRG/WP 3464
Deltamethrin and TCMTB have been subjected to several field leaching tests on freshly fallen trees and in the laboratory, using standard EN 84. All the trials gave the same results and confirm that Deltamethrin and TCMTB are not washed out after they have been allowed to penetrate the trunk surface properly. According to the EN 84 standard, less than 1% Deltamethrin and less than 1.7% TCMTB were r...

Utility pole recycling and disposal in Eastern Canada
1990 - IRG/WP 3587
Increasing public awareness, prompted by environmental groups such as Greenpeace, concerning the use and disposal of treated wood is becoming a serious issue in Canada. Producers and user groups of treated Pentachlorophenol (PCP) utility poles are at the forefront of public, government and media attention. If, as expected, further limitations on the use and disposal of PCP by the public are impose...
