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...

Penetration of deltamethrin in micro-emulsion formulation after injection in wood
1996 - IRG/WP 96-40068
In the Netherlands (and some other European Countries) the remedial treatment of death watch beetle is still a problem. This is because the larvae of this insect penetrate the central heartwood of mainly large oak beams. The heartwood is difficult to treat. The preventive treatment of wood boring insects has only recently been permitted in the Netherlands. Since 1989 injection of insecticides is r...

In search of excellence - A necessary challenge
1990 - IRG/WP 3567
Consumerism and environmentalism are gaining much influence. At national and E.C.-level the policy conducted is based on prevention of pollution through "sound" wood preservatives. Supposing that "environmental friendly" products do not exist it is understood that "sound" products have least effect on the environment during their whole life cycle. In the past only the effectiveness was paramount, ...

Sentry®), a new antisapstain formulation for protecting logs and lumber. - Part 1: advances in protection of New Zealand radiata pine logs
1999 - IRG/WP 99-30188
Until recently antisapstain formulations gave approximately 10 weeks protection to radiata pine logs and even within this time frame protection was often not consistent. Industry requires 20 weeks protection. The degree of protection sought by industry is in the order of 90-95%. For example, this equates to a maximum of 5 - 10% surface cover of sapstain in the first whole veneer produced from a pe...
