Kiln drying of CCA-treated wood - Some safety and environmental considerations
1987 - IRG/WP 3443
Vapours and condensate from a condenser kiln in which CCA-treated wood was being dried have been collected and analysed. The concentrations of arsenic, copper and chromium found in the vapours from the drying process were well below Swedish threshold limit values. The contents of arsenic and chromium were also low in the condensate, although the copper content was fairly high. The latter result wa...

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...

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...

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...

Recent development in North American industrial wood preservation plants
1988 - IRG/WP 3467
After remaining static for many years there have been a number of changes in plant design and treating cycles in recent years. This has been particularly true in the USA where few restrictions are placed on plant treating cycles by specifications; since only results type specifications are used. It is also important to realize that the AWPA Specifications for Southern Yellow Pine only call for tre...

Health and safety regulations on the use of wood preservatives in Switzerland
1980 - IRG/WP 3148
There is not any doubt that the chemical protection of wood (besides the architectional-constructional wood protection) is of utmost importance for the increase of the durability of technically used timber. The toxic properties of wood preservatives make certain legal regulations necessary for the protection of human beings, animals and the environment. Thereby wood preservatives fall under the po...
