Characteristics of chromated copper arsenate-treated wood ash.
The combustion of recovered wood from construction and demolition waste as biomass fuel is a common practice. When chromated copper arsenate (CCA)-treated wood is present as part of the wood fuel mix, concentrations of arsenic, chromium, and copper become elevated in the ash. The objectives of this study were to estimate the fraction of CCA-treated wood needed to cause the ash to fail regulator...
متن کاملArsenic availability from chromated copper arsenate (CCA)-treated wood.
Lumber used to construct raised garden beds is often treated with chromated copper arsenate (CCA). This project aimed to determine (i) how far As, Cu, and Cr had diffused away from CCA-treated wood surfaces in raised garden beds under realistic conditions, (ii) the uptake of these elements by crops, and (iii) the effect of CCA solution on soil bacteria. This study showed that As, Cu, and Cr dif...
متن کاملResidual Strength and Stiffness of Lumber from Decommissioned Chromated Copper Arsenate–Treated Southern Pine Utility Poles
The reusability of decommissioned treated wood is primarily dependent on the residual strength of the wood after service. Determining the residual strength can provide useful information for structural design and reuse of the decommissioned treated wood. This study evaluated the residual strength of decommissioned chromated copper arsenate–treated utility pole wood. Eleven decommissioned southe...
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...
متن کاملChromated copper arsenate–treated wood: a potential source of arsenic exposure and toxicity in dermatology
Arsenic-contaminated drinking water presents a serious health hazard in certain geographic locations around the world. Chromated copper arsenate, a pesticide and preservative that was used to pressure treat residential lumber in the United States beginning in the 1940s and was banned by the Environmental Protection Agency in 2003, poses a potential source of arsenic exposure and toxicity. In th...
