Testing of termiticides in soil by a new laboratory method with regard to Phoxim for replacement of chlorinated hydrocarbons
1986 - IRG/WP 1292
In comparison to chlorinated hydrocarbons insecticides of the compound classes organophosphates, carbamates and pyrethroids were tested according to an earlier described soil-test in the laboratory. The following termite-species were used: Heterotermes indicola, Reticulitermes santonensis and in addition Reticulitermes flavipes, Reticulitermes lucifugus, Reticulitermes speratus and Coptotermes for...
Cuticular hydrocarbons for species determination of tropical termites
1990 - IRG/WP 1465
Insect species have unique mixtures of cuticular hydrocarbons in the protective wax of their integument. We use hydrocarbons to evaluate similarities among termite populations. Our assumption is that colonies with similar hydrocarbon profiles are closely related. We have collected Reticulitermes in California from areas suspected to have only Reticulitermes hesperus or Reticulitermes tibialis. The...

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...

A report of the Technical Recommendations documents for the Canadian Wood Protection and Preservation Facilities and an environmental study of storm water runoff from anti-sapstain treatment plants
1988 - IRG/WP 3478
With the completion of the Final draft of the Technical Recommendations (TR) documents for the Wood Preservation and Wood Protection Industry, there are naturally questions on what is expected from these documents and how Environment Canada and Provincial regulatory agencies may interact with the wood preservation industry. In general, it is expected that the Canadian Wood Preservation and Protect...

Degradation of polycyclic aromatic hydrocarbons by laccase
1998 - IRG/WP 98-10267
The degradation of polycyclic aromatic hydrocarbons (PAH) by laccase was investigated. Laccase catalyzed oxidation of phenanthrene, solubilized in the surfactant Tween 20, exhibited an absolute requirement for the mediator compound 1-hydroxybenzotriazole. When Tween 80 was used as the solubilizing agent, the oxidation rates were more than six times higher as compared to Tween 20. Using the thiobar...

The gaseous environment of Coptotermes lacteus mound colonies before and after mirex treatment
1989 - IRG/WP 1396
While monitoring the halocarbon and hydrocarbon emissions from a dry sclerophyll eucalypt forest in central Gippsland, similar emissions were collected from within several Coptotermes lacteus mound colonies. Samples of the gases (hydrocarbons) from within the mounds were collected before, during and after treatment with mirex-treated wood-decay blocks. All the mirex-treated mounds died within two ...

Bacterial Degradation of Pentachlorophenol Indicated in Groundwater Undergoing Long Term In-Situ Remediation
2016 - IRG/WP 16-50318
Pentachlorophenol (PCP, Penta) is a worldwide soil and water contaminant. The pervasive use of PCP as a fungicide, herbicide, pesticide, and as preservative for wood products has led to its global distribution. It is a highly effective preventative measure for most invasive insects, bacteria, fungi, and molds, as well as an excellent wood protection treatment. This study examined a known PCP conta...
