Organic solvent preservatives. Essays on the ecotoxicology of new formulations
1991 - IRG/WP 3642
The knowledge on the ecotoxicological profile of wood preservatives become more and more important. The acute toxicity against aquatic organisms was examined for oil-borne preservatives, based on combinations of new fungicides (Tebuconazole, Propiconazole, Dichlofluanid) and insecticides (Permethrin, Cyfluthrin). These tests were conducted with fish, daphnia and algae. In principle the different f...

Bioaccumulation of pentachlorophenol in rainbow trout and zebra fish muscles
1986 - IRG/WP 3372
The bioaccumulation of pentachlorophenol in Rainbow Trout and Zebra fish has been evaluated by partition coefficient n-octanol/water determination at ph 7 and measured in vivo according to the OECD guidelines and the European directive 79/831/EEC. The obtained results confirm the low bioaccumulation potential of this product in aquatic organims....

Di-sodium fluorophosphate, a new fluorine containing, water-borne wood preservative
1986 - IRG/WP 3373
The physical, chemical properties of Di-sodiumfluorophosphate (Na2PO3F) are compared with those of a trade-mark SF-salt. The opposition of biological activity and toxicological data showed that Di-sodiumfluorophosphate may be a suitable alternative to SF-salts ( based on MgSiF6)....

Practicability of bioassays in the evaluation of environmental risks in wood protection
1996 - IRG/WP 96-50071
As an example for the proofing of the practicability of bioassays in the evaluation of environmental risks in wood protection the ecotoxicological behaviour of CCF-impregnated timber was examined. After vacuum pressure impregnation specimen from shaped pine poles were tested on ecotoxicological effects of leachable compounds using sensitive aquatic organisms like fish, Daphnia and algae as bioindi...

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...

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...

Construction of dhows in Kuwait
1981 - IRG/WP 465
To most people Kuwait means oil and the opulence associated with it, but to the seafarer, Kuwait means Dhows. There are as early references to the Kuwaiti Dhows as the 17th century. The Danish explorer Nebuhr in 1756 described Kuwait as having a work power of 10,000 people and 800 wooden boats involved in fishing, pearl diving, and trade. Dhows might well have been the original carriers of "The Pe...

Observations on the destruction of fishing craft in India by marine wood-borers with special reference to the West Coast
1981 - IRG/WP 468
The paper highlights the economic importance of the destruction of fishing craft in India by marine wood-destroying agencies. The annual loss involved is to the extent of over 94 million rupees. Thirty-nine spectes and one variety of woodborer have so far been recorded from India, of which Bankia campanellata, Bankia carinata, Bankia rochi, Dicyathifer manni, Lyrodus pedicellatus, Teredo clappi, T...

Creosote and cancer -Cancer incidence among workers exposed to creosote
1990 - IRG/WP 3572
Creosote is a wood preservative that contains polycyclic aromatic hydrocarbons, which are known to be carcinogenic. Cancer incidence among 919 male workers in Sweden and Norway exposed to creosote in the wood preserving industry was studied. The expected numbers of cases were based on the incidence rates of cancer according to the Cancer Registries of Sweden and Norway. A total of 129 cancer cases...
