Environmental behaviour of treated wood in (semi-)permanent contact with fresh or seawater
1998 - IRG/WP 98-50101-20
This study presents a strategy for the environmental toxicity evaluation of treated wood towards the aquatic compartment, using non target water organisms toxicity tests. A lixiviation process is applied on wood (Pinus sylvestris) treated with several wood preservatives formulations. The lixiviation process is carried out in the laboratory with ultrapure water or synthetic seawater. After chemica...

Accreditation: mutual benefits for research and industry
2010 - IRG/WP 10-20452
The wood preservation laboratory of the CIRAD had its first ISO 17025 accreditation from the COFRAC in 2006 for 5 standardized test procedures. The so called “first cycle” of its accreditation will be mid-2010. This laboratory is now accredited for 8 tests and is planning to increase the field of its quality management and accreditation. This poster describes how research projects, pre-normati...

Assessment of treated wood leachates genotoxicity with a bacterial test
1997 - IRG/WP 97-50089
Genotoxicity is known as the damage caused by environmental stressors (biological, chemical and physical) on the genetic material of an organism. This toxicological effect can be assessed by a lot of biological assays and especially by bacterial tests. These tests are frequently performed on environmental samples or on pures substances and are in that case, strongly correlated to the carcinogenic ...

Succession after Fire of Fungal Fruiting Bodies in Mediterranean Pinus pinaster Stands in Spain
2012 - IRG/WP 12-10789
In this study we present the results of a 4-year survey aimed at describing the succession of fungal communities following fire in a Mediterranean ecosystem in Northwest Spain, dominated by Pinus pinaster Ait. After a large wildfire in 2002, six 2 x 50 m study plots were established in burned and unburned areas corresponding to early and late succession stages. During the autumn seasons from 2003 ...

Durability of tropical species from Peru according to European Standards
2020 - IRG/WP 20-10964
Natural durability is defined as the intrinsic resistance of wood against the attack of destructive organisms. There are standardized methods to estimate a durability value. In Europe, the standard EN-350 is responsible for establishing the basic guidelines, as well as the necessary tests to determine this value, which is essential to know the degree of protection needed for the tested wood to ext...

Validating a short-term laboratory method to assess the resistance of timber to biodegradation by marine wood-borers
2021 - IRG/WP 21-10975
Novel approaches to protecting wood in coastal and marine environments are needed as the use of traditional broad-spectrum biocides are now restricted. Wood is widely utilised in marine environments where it can be rapidly degraded by wood-boring organisms, causing billions of dollars of damage per annum. Biocidal compounds such as CCA and creosote have been popular treatments for timber products ...

Wood modification reduces the feeding rate of the wood boring crustacean, Limnoria quadripunctata
2022 - IRG/WP 22-10993
Adult Adult Limnoria search for new wood once their current piece disintegrates from tunnelling. During this time, they do not have access to wood so experience a period of starvation and must feed again once settled. Wood modification offers protection to marine structures by reducing the feeding rate of Limnoria and therefore can reduce recruitment of adults from distant pieces of wood. Chemical...
