Leaching and fixation characteristics of chrome-copper-fluoride-zinc (CCFZ) treated wood
1996 - IRG/WP 96-30096
The leaching characteristics of radiata pine sapwood blocks treated with CCFZ were evaluated by the AWPA standard leaching test. The rate of fixation of the preservative components in CCFZ treated radiata pine were also evaluated by quantitative analysis of solution expressed from the treated wood. Both leaching and fixation characteristics of CCFZ were compared with CCA-Type C treated wood sample...

Biological Safety Evaluation of Animal Contact of Preservative-Treated Wood
2003 - IRG/WP 03-50196
Biological safety of preservative-treated woods that could be contacted to human and animal was evaluated for rat and rabbit exposed to CCA-, ACQ- and CCFZ-treated woods. The accumulation of preservatives ingredient in the rat’s plasma and viscera, and the transforming function of replacing preservatives were examined in this study. The result indicated that preservative-treated wood did not bri...

Basilit CCFZ. Further studies on ecotoxicological behaviour
1992 - IRG/WP 92-3722
Basilit CCFZ is a new developed water based preservative for the protection of timber in hazard class 4 and 5 (ground-, fresh- and salt-water contact). The active components of this salt are copper, chromium, zinc and fluorine. In addition to primarily studies on the acute toxicity against organisms of the aquatic food chain a long term ecotoxicological study was performed. In a prolonged toxicity...

CCFZ, a new type of water-borne wood preservative for vacuum pressure impregnation
1991 - IRG/WP 3643
By combination of CCF-Salt types with zinchexafluorosilicate a remarkable improvement of efficacy is achieved. In the same time the ecotoxicoligical data become more save. As well as the efficacy against wood-destroying organisms (Basidiomycetes, Soft rot and Long horn beetle) the basic data to evaluate the ecotoxicological behaviour of a CCFZ-Salt are described and compared with the properties of...
