Download or read book Ammoniacal Copper Arsenate Wood Preservation Facilities written by Canada. Conservation and Protection and published by Environment Canada. This book was released on 1988 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a federal strategy to protect the environment and human health from potentially toxic commercial chemicals, Environment Canada has evaluated chemical use practices within the wood preservation industry. During 1982-84, Envirochem Services was retained to visit and review practices at 19 wood preservation facilities operating in four Canadian provinces, and to document the findings. In July 1984, Environment Canada established a Wood Preservation Industry Technical Steering Committee to develop technical recommendations for wood preservation facility design and operational measures which would: reduce or eliminate the release of wood preservative chemicals to the environment; and minimize the exposure of workers to wood preservation chemicals.

Download or read book Heavy Duty Wood Preservatives written by Canada. Pest Management Regulatory Agency and published by . This book was released on 2010 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Proposed Re-evaluation (PRVD) summarizes the science evaluation for creosote, pentachlorophenol, chromated copper arsenate and ammoniacal copper zinc arsenate and presents the reasons for the proposed re-evaluation decision. It also proposes additional risk-reduction measures to further protect human health and the environment. The information is presented in two parts: i) the Overview describes the regulatory process and key points of the evaluation (i.e. the Science Evaluation summary); ii) while the full Science Evaluation provides detailed technical information on the human health, environmental and value assessments of creosote, pentachlorophenol, chromated copper arsenate and ammoniacal copper zinc arsenate. Though the PRVD is a consultation document, consultation has already taken place on the science evaluation and risk assessment component of these re-evaluations.--Document.

This book was released on 1992 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of the waterborne wood preservative, ammoniacal copper zinc arsenate (ACZA), is likely to increase in the near future because of environmental concerns associated with oilborne preservatives. Developing an understanding of the permanence of this preservative in wood will become important from both environmental and performance standpoints. Conventional thinking suggests that ACZA components are stabilized in the wood by the precipitation of metal/arsenate complexes as the ammonia evaporates, but little work has been done to confirm this theory. Experiments were conducted to clarify the mechanisms which stabilize, or "fix" copper, arsenic and zinc within ACZA treated wood. Studies were undertaken to determine the effect of ACZA composition on fixation, the role of wood components in fixation, the role of precipitation in fixation, the order of precipitation of ACZA components, the sites of copper and zinc adsorption within the treated wood, the bonding environment of adsorbed copper, and the microdistribution of copper, zinc and arsenic within treated wood. The results of these experiments generally support the finding that arsenic fixation occurs by precipitation of metal/arsenate, complexes as ammonia evaporates from the treated wood. Arsenic leaching was minimized when the metal oxide:arsenic pentoxide ratio in the treating solution exceeded 2.0, and when a portion of the copper was replaced with zinc. Subsequent tests revealed that zinc precipitated the majority of arsenic when the ammonia was allowed to evaporate from the treating solution. In contrast, the metal cations are not dependent on arsenic for fixation because they have low water solubility and undergo adsorption reactions with the wood. Copper, in particular was readily adsorbed by the lignin and heartwood components of wood, suggesting that phenolic groups were primary reaction sites. Further tests with lignin model compounds also suggested that copper reacted preferentially with the hydroxyl groups of phenolic compounds. Adsorption of the metals to the wood can interfere with arsenic fixation by reducing the availability of metal cations in the preservative solution. The severity of arsenic leaching due to metal adsorption could be affected by many treatment variables, and more work is needed to determine how these variables could be manipulated to minimize arsenic fixation.
