The dip diffusion treatment of tropical building timbers in Papua New Guinea
1972 - IRG/WP 310
In Papua New Guinea a dip diffusion process using a multi salt preservative developed by C.S.I.R.0. has been in commercial use for 8 years. Over 200 million super feet (236,000 m³ ) of timber has been treated during this period and current rate of treatment is 34 million super feet (80,400 m³ ) of timber per year in 70 licenced treatment plants. The process has been found to be simple to apply, ...

Determination of fixation properties by bioassays - A proposal for the assessment of safety indexes in wood protection
1990 - IRG/WP 3566
In the determination of environmental effects of chemicals tests with fishes, daphnia and algae have proved to be practicable. With respect to wood protection such bioassays are suitable to control effects of treated timber against aquatic organisms. By using the fish-acute-toxicity-test the development of a laboratory test method is described for the checking of the fixation rate of a copper-chro...

A status report on code of good practices
1991 - IRG/WP 3679
Code of Good Practices - Anti Sapstain documents, presented to IRG meetings in the past, are the basic documents for health and safety of the workers and the environment in Canada. The BC Ministry of Environnment has now issued regulations in the area of effluent discharge. While Pentachlorophenols (PCP) are not used by the industry, the documents are still used as a guideline document for the oth...

Proposal for further work on fixation of CCA-preservatives in wood
1988 - IRG/WP 3493
Many studies on the fixation and fixation-mechanism of CCA-preservatives in lignocellulose materials have been published but few on the practical consequences of this knowledge. For the wood preserving industry and the user of treated wood it is important to know what is meant by the word fixation, when fixation is complete and how fixation can be recorded in an easy way according to a non-destruc...

Safe application of copper-chrome-arsenate preservatives
1975 - IRG/WP 377
All wood preservatives contain biologically active substances and must, by design, be in some measure toxic to man. There is nothing fundamentally difficult, however, about using a wood preservative with complete safety. It depends on knowing the risks to health and/or the environment, which the preservative may present, and planning application accordingly. In this paper we examine these and othe...

Industrial wood preservation in Kenya. Present status – future prospects
2005 - IRG/WP 05-30385
Although some 50 years old, industrial wood preservation in Kenya does not appear to have technically, scientifically, and commercially evolved and contributed to significantly extend service lives of timbers, protect health and the environment, and curb unnecessary over-exploitation of forests. The population of the country has increased by 530% over the past 50 years; regular excisions have red...

Will political initiatives stop the use of preservative-treated wood in Sweden?
1990 - IRG/WP 3578
The Swedish government has initiated several investigations on how to reduce the use of different chemicals. Among these chemicals are creosote, arsenic, chromium and organotin. A special investigation was carried out concerning wood preservatives resulting in different proposals on how to reduce the use of preservatives and preservative treated wood. The most important proposals were an "environm...

Zur Analytik von Pentachlorphenol und Tetrachlorphenol in der Luft und im Urin. [On the analytics of pentachlorophenol and tetrachlorophenolin the air and in urine]
1979 - IRG/WP 3139
Because of its excellent fungicide and insecticide properties PCP has been used for more than three decades in the field of wood preservation. Recently, however, its application has been criticized repeatedly. The motives for criticism were diseases, the origin of which was supposed to be closely connected with the use of pentachlorphenolic wood preservatives. The quantitative evidence of this sub...

Wood colonizing fungi as a human pathogen
1992 - IRG/WP 92-1523
Today we recognize some 174 "pathogens" among the approximately 100000 species of fungi, which cause different diseases on man. 24 fungi which are well known as wood colonizing fungi have been identified as opportunistic human pathogen. Some of them have been found on the surface of the human body, causing superficial mycoses, or cutaneous infection, like dermatophytosis or dermatomycosis. Other c...

Borates as wood preservatives - an environmental, health and safety perspective
1993 - IRG/WP 93-50001-03
Boron compounds are highly effective wood preservatives and have an established safe use in the timber treatment industry. Their widespread background occurrence in nature, low acute mammalian toxicity and useful properties make them versatile active ingredients within today's environmentally aware society. A critical review of health, safety and environmental data on the borates, their u...

Leaching from CCA-impregnated wood to food, drinking-water and silage
1987 - IRG/WP 3433
During the last years The Norwegian Institute of Wood Technology (NIWT) has analysed different foodstuff for contamination by copper, chrome and arsenic from CCA-impregnated wood. There has been some interest for using CCA-impregnated wood in contact with food and drinking-water. Before giving their permission the Norwegian Health Authorities want results from experiments. NIWT therefore started t...

Chromium in wood preservation: Health and environmental aspects
1978 - IRG/WP 3120
The majority of water-borne salts in current use contain hexavalent chromium, usually as dichromate or chromium trioxide. In about 1913 it was suggested that chromates, phosphates or borates could be added to the sodium fluoride and dinitrophenol mixtures then in use in order to inhibit corrosion. Dichromates were found to be most suitable and the resulting mixture known as Thriolith and later Tri...

Tributyltin compounds in wood preservation: Health and safety aspects
1986 - IRG/WP 3396
The toxicity of organotin compounds of the general formula RnSnX(4-n) depends strongly on the type of organic substituent R and on the degree of substitution n. The residues X, not bound through a tin-carbon bond, are however of much smaller influence. Furthermore, there is evidence that hydrolysis of tributyltin esters will occur under environmental as well as under physiological conditions to TB...
