Leaching of CCA from Pinus patula during marine trials in the southern hemisphere
1991 - IRG/WP 4167
Pinus patula stakes were treated with CCA to retentions of 31 kg/m³ salts, and were sited in the sea of Port Alfred, South Africa, for two years. Samples were then removed to the laboratory and analysed as before for copper and arsenic. Prelimiary data showing CAA losses from these stakes in the marine environment showed that CCA was longitudinally leached from them, and was also transversly redi...

Surface accumulation of copper on CCA-impregnated Pinus patula stakes during marine preservative trials in the southern hemisphere
1992 - IRG/WP 92-4181
Pinus patula stakes treated with CCA to target retentions of 30 kg/m³ salts were exposed to sea water in marine and estuarine ecosystems off the coast of Southern Africa for two years. Samples were then analysed for copper and arsenic. Analysis of samples from the marine ecosystem showed (IRG/WP/4167) that arsenic was longitudinally and transversely leached from the wood, whereas the copper was r...
