Brief Review of “Leaching and Toxicity of CCA-Treated and Alternative- Treated Wood Products.

Brief Review ofLeaching and Toxicity of CCA-Treated and Alternative-Treated Wood Products

ObjectivesConduct a side-by-side comparison of CCA-treated wood and alternative chemical-treated wood with respect to relative chemical leaching and relative aquatic toxicity of leachatesGather basic data that can be used as part of overall assessment of preserved wood types

Wood PreservativesCCA- chromated copper arsenateACQ- alkaline copper quaternaryCBA- copper boron azoleCC- copper citrateCDDC- copper dimethyldithiocarbamate

Leaching TestsSPLP- Synthetic Precipitation Leaching ProcedureTCLP- Toxicity Characteristic Leaching ProcedureSynthetic seawater (Instant Ocean)DI water
