CCA-preserved wood: efficiency, deleterious potential, toxicity of wastes and recovery technologies
Abstract
Timber is a sustainable material that may be employed to several ends. Its durability is prolonged by chemical preservers, especially Cromated Copper Arsenate (CCA). However, timber wastes after treatment and usefulness cause adverse environmental results. Recovery and final layout of CCA-timber may be undertaken distinctly with an improvement in the preservation of the environment. Current research involved the efficaciousness of CCA-treated timber and its potential toxic effect by reviewing the recovery of CCA from the wood, the final layout of contaminated solid residues and potential replacements. There are many publications on the theme, especially in the USA, even though political and environmental pressure exists for diminishing the use of CCA in timber conservation. Further, current analysis identified the main journals on the theme, their impact and the categorization of the main subject matters, with special reference to adverse environmental potential of CCA-treated timber. Data comply with those on the Portal of Journals of CAPES for the last ten years on the theme and the state-of-the art of studies on the subject.References
