Some tests on ES - AS 11, a novel anti-sapstain formulation, and its properties
1987 - IRG/WP 3399
The results of some tests with the formulation ES - AS 11 are given. The formulation is an attempt to improve the performance of an anti-sapstain chemical by: 1) increasing its penetrability 2) uniquely combining its active ingredients. Very short times of treatment (dipping not longer than 5 seconds), low concentrations of active ingredients, and lower toxicological and environmental risks may be...

A review of environmental emissions from building and construction materials in comparison with preserved wood
2005 - IRG/WP 05-50224-11
A review of the public domain literature concerning emissions to the environment from materials which are used in the construction of buildings (e.g. Concrete, Asphalt, Galvanised Steel), in comparison with preserved wood, and a review of the approaches taken by the construction sector in assessing the risk from environmental emissions, in comparison with the approaches taken by the wood preservat...

Health hazards and environmental aspects when using Cu-HDO-containing wood preservatives in vacuum pressure plants
1993 - IRG/WP 93-50001-11
Apart from the biological efficacy of wood preservatives, the health and environmental aspects concerning the utilisation of wood preservatives, the use of treated timber and the disposal of impregnated wood are of high significance today. Therefore, information on a possible aerial concentration of wood preservatives, on the mobility of active substances in soil leached from treated timber in ser...

Fungus cellar and field tests with tall oil derivatives. Final report after 11 years' testing
1993 - IRG/WP 93-30007
Two derivatives of tall oil were tested as wood preservatives in a fungus cellar and in ground contact (field test). Stakes of Pinus sylvestris sapwood were used in the tests. For the field test the size of the stakes was 20 x 50 x 500 mm³ and for the fungus cellar test 20 x 20 x 250 mm³. The stakes were vacuum-pressure treated with the two products and exposed in 1981. The field test site used ...

Evaluation of an alkyl ammonium compound as a fungicide to control sapstain and mould during diffusion storage
1984 - IRG/WP 3282
An alkyl ammonium compound ('Akzo' ES 255) was evaluated for its effectiveness against mould and sapstain during diffusion storage of boron-treated rubber wood. Though ES 255 at 1.0% concentration was effective against mould (71%) and sapstain (89%) it is less satisfactory compared to 0.5% sodium pentachlorophenoxide against mould (92%) and sapstain (98%)....

A rapid colorimetric assay for mold spore germination using XTT tetrazolium salt
2011 - IRG/WP 11-20462
A rapid colorimetric assay was developed to quantitate metabolic activity in mold spores during germination using 2,3-Bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[9phenyl-amino)carbonyl]-2H-tetrazolium hydroxide (XTT). The assay was used to demonstrate inhibition of spore germination following exposure to different biocides and variability in the inhibition of spore germination of different mold specie...

A new model for wetting and drying of wood end-grain – with implications for durability and service-life
2011 - IRG/WP 11-20477
New experimental data for wetting and drying of wood end-grain, Sandberg (2009), imply that traditional models for moisture transport are not at all applicable. A new model is developed to consider the phenomenological behaviour of water transport in and out of end-grain, using the pore water pressure and sorption scanning properties. Modelling results are compared to experimental results and the ...

The Effect of Soil pH on the pH of Treated Southern Pine in Ground Contact after 12 Months
2011 - IRG/WP 11-50281
Southern pine samples treated with soluble and particulate copper solutions were subjected to three soils that had been amended to provide acidic, neutral and alkaline conditions. Wood pH was measured prior to, and after 6 and 12 months after being placed in the soil to determine the effect of soil pH on wood pH....

Future Directions Regarding Research on the Environmental Impacts of Preservative-Treated Wood: Environmental Impacts of Preservative-Treated Wood. February 8-11, 2004, FL, USA
Workshop – Research Needs
2004 - IRG/WP 04-50222
This paper presents a series of documents that focus on research needs for potential future work focusing on the environmental impacts of preservative-treated wood. These documents were developed through a conference sponsored by the Florida Center for Environmental Solutions (FCES), located in Gainesville, Florida. The conference was held in Orlando, Florida, February 8 – 11, 2004 and the tit...

Mobility and bioavailability of wood preservation chemicals in soil - actual field measurements
1998 - IRG/WP 98-50101-11
Wood material intended for outdoor use is often impregnated with chemicals to withstand attack from fungi and bacteria. Both inorganic and organic substances are used to protect the wood, and they are used in a toxic and bioavailable form. At wood preservation facilities severe soil contamination can be encountered due to spills and deposition of sludge, especially at old sites. Two sites, one whe...

Strategies of risk reduction in sensitive environments - Case studies
2001 - IRG/WP 01-50166-11
The application of risk assessment procedures is based on widely agreed criteria and, whenever necessary, default values. The assessment itself aims to cover a wide extent of situations through "reasonable worst case scenarios". The result, based on the ratio of predictive to no-effect concentrations "PEC/PNEC", is usually performed into various regulations on a pass/fail basis, practically by ban...

Quality and safety scheme for wood in food contact
1995 - IRG/WP 95-50040-11
When there is no tolerance concerning the content in food of potential contaminants the scheme is limited to a ban of any contaminant with objectives of undetectable amounts at the limits of detection of the chemical analysis. When some tolerances exist, there is a need to check the compliance of a production to such requirements, putting in place the necessary prevention of any accidental situati...

The natural durability and preservative treatability of 11 bamboo species
2010 - IRG/WP 10-10708
Tests on the natural durability and preservative treatability of 11 common bamboo species were conducted. The results showed that there was a linear relation between bamboo density and its preservative retention by mass, and the preservative retention of bamboo reduced while its density increased. The test also showed that there were significant differences in the natural durability of bamboos, bu...

Chapter 11 - Preservation of talla bamboo
2007 - IRG/WP 07-10635-11
Researches revealed that the talla bamboo (Bambusa tulda Roxb.))
in Bangladesh could be full-cell pressure treated with CCA in green
and dry conditions. The dry bamboo gives higher loading
absorptions than green one when impregnated at same treating
conditions. Also higher absorptions are obtained at nodes rather
than internodes. Adequate penetration and retention results for
ground and wate...
