Bacterial Associations with Decaying Wood: a Review
Wood-inhabiting bacteria are associated with wood decay and may have an indirect influence on the decay process. Bacteria are able to affect wood permeability, attack wood structure, or work synergistically with other bacteria and soft-rot fungi to predispose wood to fungal attack. Bacteria that can inhabit chemically treated wood are recognized. The natural ability of certain bacterial genera ...
متن کاملA Preliminary Comparative Toxicity Assessment of Materials Used in Aquatic Construction
Environment Canada undertook a preliminary comparative toxicity assessment of selected materials that may be utilized in construction projects located in the aquatic environment. That project involved introducing Fahlstrom sized test stakes (3.9x0.54x26.4 cm) to both fresh and salt water for toxicity testing. Rainbow Trout, Daphnia magna and Microtox testing was conducted in freshwater and Thre...
متن کاملSpecial treatment: disposing of CCA-treated wood.
B uilding outdoor structures such as decks, docks, and playgrounds often signifies the pursuit of a more healthful lifestyle, but the wood used in much of this construction poses potential environmental and health problems when these structures are demolished. The chemicals that preserve the wood, primarily the inorganic waterborne preservative chro-mated copper arsenate (CCA), are designed to ...
متن کاملComparative Study on Liquefaction of Creosote and Chromated Copper Arsenate (CCA)-treated wood and Untreated Southern Pine Wood: Effects of Acid Catalyst Content, Liquefaction Time, Temperature, and Phenol to Wood Ratio
Creosoteand chromated copper arsenate (CCA)-treated wood waste and untreated southern pine wood were liquefied with phenol and sulfuric acid. The effects of sulfuric acid content, liquefaction time, liquefaction temperature, and phenol to wood ratio on liquefaction rate (i.e., wood residue content) were investigated and analyzed by analysis of variance (ANOVA). The results showed that both creo...
متن کاملChemical Structure of Arsenic and Chromium in Chromated Copper Arsenate (CCA) Treated Wood
In recent years, regulatory and public attention has become focused on the potential risks associated with exposure to chromated copper arsenate (CCA)-treated wood – the most widely used wood treatment product in the United States. CCA has been used to treat lumber for over 60 years (1), mainly because of the extended lifetime of CCA-treated wood as compared to untreated wood (2-5) and the high...
