Chlorodioxins in pentachlorophenol
1975 - IRG/WP 346 E
At the 6th meeting of the IRG/WP plenary group held on 20 June, 1974, in Vienna, Mr Richardson expressed some concern about dioxins which might be contained as impurities in pentachlorophenol and in sodium pentachlorophenoxide or which might be formed during the combustion of treated wood. He mentioned the malformations that have been noted in Vietnam due to the teratogenic action of the 2, 3, 7, ...

The metabolism and comparative elimination of polychlorinated biphenyl congeners in termites
1993 - IRG/WP 93-10038
Termites may serve as a potential supplementary food source for fish, poultry and pigs. Waste paper may be used as a source of food in mass rearing the termites. However, paper products and printing inks contain trace levels of toxic xenobiotics e.g. polychlorinatecl biphenyls (PCBs) and dioxins. This study examined the ability of Mastotermes darwinensis and Coptotermes acinaciformis to metabolise...

Formation of polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) during the combustion of impregnated wood
1995 - IRG/WP 95-50040-19
Wood waste and industrial wood residues often contain various preservatives. The waste management for these residuals can be recycling, deposition or combustion. Among the three possibilities, combustion seems to be the most efficient way of disposal. To obtain detailed information about emissions of organic compounds with environmental impact, especially polychlorinated dibenzo-p-dioxins (PCDD) a...

Pentachlorophenol - The US and Canadian experience
1995 - IRG/WP 95-50040-26
Pentachlorophenol ("Penta") is a highly effective and economical wood preservative. The principal use in the United-States and Canada is pressure-treatment of wood; major applications are for railroad ties, pilings, posts, cross arms, and poles. Treatment of wood products with pentachlorophenol typically extends the functional life of wood by at least eight times. Because of the presence of certai...
