Chemical investigation of 23-year-old CDDC treated southern yellow pine
1997 - IRG/WP 97-30141
The effect of 23 years exterior exposure on CDDC treated southern yellow pine was evaluated by the application of solid state analytical instrumentation. Analytical methods including environmental scanning electron microscopy (ESEM),energy dispersive X-ray analysis (EDXA), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), inductively coupled plasma (ICP) and atomic absorption spectr...

Laboratory aquaria evaluation of CDDC (copper dimethyldithiocarbamate) against marine borers
1998 - IRG/WP 98-10262
The performance of CDDC (copper dimethyldithiocarbamate) and CCA (copper chrome arsenic) treated timber blocks was examined in a 1.5 year aquaria bioassay against the marine borers Limnoria tripunctata Menzies and Lyrodus pedicellatus (Quatrefages). Three timbers, southern yellow pine (SYP), Pinus radiata D. Don and Eucalyptus regnans F. Muell were treated with CDDC to retentions of 16, 32, 48 and...

Comparison of Temporal Changes in Metal Leaching and Aquatic Toxicity from Wood Treated with CCA and Alternative Preservatives
2005 - IRG/WP 05-50236
This study compares the temporal variation of chemical leaching and aquatic toxicity of wood treated with chromated copper arsenate (CCA) and other copper-based wood preservatives (alkaline copper quaternary (ACQ), copper boron azole (CBA), copper citrate (CC) and copper dimethyldithiocarbamate (CDDC)). Treated wood blocks were leached for 21 days and the leachate collected was analyzed for prese...
