Risk assessment and the approval of wood preservatives in the United Kingdom
1995 - IRG/WP 95-50040-23
An approval system operates in the United Kingdom (UK) for the regulation of wood preservatives. The regulatory authority uses a risk assessment approach to evaluate how far the potential for harm to people and the environment from wood preservatives is likely to be realised in practise, and hence the controls required for products to be, used safely. The evaluation for approval purposes also take...

Feasibility study for a dedicated pressure treated wood waste management system
2005 - IRG/WP 05-50224-22
For the creosote treated wood coming out of service, it has been estimated an amount of 200 000 t per year for the next twenty years, and 100 000 t per year afterwards. With a limited number of actors, mainly SNCF (as producer and as user), no importations, and available energy recovery options, it appears possible for setting a dedicated wood waste management system, if the SNCF agrees to.
For t...

Developements in the EEC on the regulation of wood preservatives
1993 - IRG/WP 93-50016
There is a wide variation in the regulation of wood preservatives within the EEC, ranging from product by product authorization under persticides legislation to controls via standards, or simple compliance with basic requirements on classification packaging and labelling. During the past two years the commission of the European Communitiesn has worked on a proposal concerning the placing on the ma...

Forest management policies and timber supplies in British Columbia
1997 - IRG/WP 97-10244
British Columbia has a huge wealth of timber resources, currently exceeding 7 billion m3 of mature timber on about 43 million ha classified as productive forest lands. That land area also supports a current volume of over 2 billion m3 of timber in immature stands. How much of the volume will be made available as an annual timber supply for the forest industry is dependent upon a set of policies go...

Pest control products act. An overview of regulation of heavy duty wood preservatives
1995 - IRG/WP 95-50040-30
The regulation of pesticides in Canada is carried out under the authority of the Pest Control Products Act and Regulations. Products which control, prevent, destroy, mitigate, attract or repel a pest are required to undergo a presale assessment for safety, merit and value. This review will determine whether a product, when used according to label directions, can be used both safely and will be eff...

Tendency of the preservative use for impregnation industries in Japan
1998 - IRG/WP 98-50101-05
In Japan, since 1997, the acceptable limit of the arsenic in the waste water become to 0,1 mg/l and the additional regional severer restriction can be established. In this reason, Japanese wood preservation industries intend to use other than CCA, like DDAC, ACQ, Tanalith CuAz, copper-naphthate and zinc-naphthenate, as replacing from CCA. In Jan-June 1997, the share of CCA preservatives was less t...

Effect of Volatiles from Trichoderma species on the regulation of protein synthesis in Serpula lacrymans isolates
2002 - IRG/WP 02-10440
The growth of wood decay fungi has previously been shown to be inhibited by volatile organic compounds (VOCs) from selected Trichoderma isolates. No mechanism of action has however been established for such inhibition. This paper reports the effects of VOCs produced by Trichoderma pseudokoningii, T. viride and T. aureoviride on the growth of four dry rot isolates and corresponding protein synthesi...

Regulation of hyphal sheath formation iron-chelator production by the brown rot fungi Gloeophyllum trabeum and Postia placenta
1994 - IRG/WP 94-10074
Hyphal sheath formation and iron-chelator production by liquid cultures of the brown rot fungi Gloeophyllum trabeum and Postia placenta were monitored over time. The effects of incubation at various temperatures, pH's and concentrations of iron, manganese and nitrogen were determined. Hyphal sheath production was observed microscopically and quantified with JAVA video analysis. The hyphal...

Redox regulation of enzyme activity during wood decay
1996 - IRG/WP 96-10172
A potential strategy in the search for alternative wood preservatives against fungal decay is to target the extracellular wood-decay process itself, rather than the decay organisms. This presents novel targets for selective disruption and possibly without the broad-spectrum toxicity associated with conventional wood preservatives. The enzymes of white rot decay are mechanistically diverse (e.g. hy...

EPA’s Current Views on Heavy-Duty Wood Preservative Regulation
2003 - IRG/WP 03-50206
This paper describes the current EPA system for regulating pesticides and wood preservatives. In particular it focuses on the voluntary phase-out of CCA for residential uses after December 30, 2003, which was agreed between the CCA manufacturers and EPA. Even though the EPA reached an agreement with industry to phase out CCA for residential uses, EPA is continuing the most rigorous risk assessmen...

Wood preservation in Canada - Regulation and Registration
2001 - IRG/WP 01-50166-02
The Canadian wood preservation industry is at a critical juncture now as a number of initiatives converge on the industry over the next few years. Issues facing the industry include: Re-evaluation of the conventional wood preservative chemicals - inorganic arsenicals, creosote and pentachlorophenol targeted for July 2001. Delayed registration of new actives as a result of re-evaluation activity an...

What is OECD doing to promote harmonization of biocide regulations
1999 - IRG/WP 99-20182
OECD began work on biocides in 1997 to help Member countries co-operate in the assessment and registration of these products. The work is a part of OECD's Pesticide Programme, and is co-ordinated by the Biocides Steering Group. The goal is to harmonize regulatory approaches to allow countries to conduct evaluations of biocides more efficiently. More efficient evaluations can advance the p...

Influence of Exposure Direction on Leaching of a Biocide from Painted Wood Surfaces
2014 - IRG/WP 14-50303
The objective of this project was to investigate the influence different exposure directions – North, East, South and West on the cumulative quantity of a biocide leached from painted wood surfaces due to rainfall and the consequences for the risk assessment.
The study included a solvent-borne primer without biocides and a topcoat protected with a biocidal active substance. Both products were a...

Biocidal Products Regulation – Structure and Impact for Product Authorization and Testing in EU
2014 - IRG/WP 14-50308
Since September 2013 the Biocidal Products Regulations (BPR) has been in force in Europe. BPR replaces the Biocidal Products Directive (EC/98/8) and in some respect marks a turning point in the European legislation concerning registration of all types of biocides.
BPR introduces some changes both for suppliers of active substances and for companies that produce and place biocide containing wood p...

2016 - IRG/WP 16-40728
Microencapsulated phase change materials (MicroPCMs) containing dodecanol were fabricated using melamine-formaldehyde (MF) or polyethylene glycol 200 modified melamine-formaldehyde (PMF) resin as the shell materials by in situ polymerization. Wood flour/high-density polyethylene (WF/HDPE) composites with MF shell MicroPCMs (MF-MicroPCMs) or PMF shell MicroPCMs (PMF-MicroPCMs) were prepared, respec...

Guidance on the European Biocidal Products Regulation Concerning Efficacy of Wood Preservatives
2017 - IRG/WP 17-20627
In Europe wood preservatives belong to Product Type 8 (PT8) of the Biocidal Products Regulation (BPR, EU n. 528/2012), which regulates the authorisation of biocidal active substances and products in the European market.
The applicant, who aims to obtain authorization to place a product onto the European market, needs to submit data to substantiate the label claims for the intended uses. Label cla...
