This book was released on 1988 with total page 110 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 facilities operating in four Canadian provinces, and to document its findings. In July 1984, Environment Canada established the Wood Preservation Industry Technical Steering Committee to develop technical recommendations for wood preservation facility design and for operational measures which would: reduce or eliminate the release of wood preservation chemicals to the environment; and reduce to a minimum the exposure of workers to wood preservation chemicals.

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.
Book Synopsis Alternatives to Chromated Copper Arsenate for Residential Construction by : Stan T. Lebow
Download or read book Alternatives to Chromated Copper Arsenate for Residential Construction written by Stan T. Lebow and published by . This book was released on 2004 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: For decades chromated copper arsenate (CCA) was the primary preservative for treated wood used in residential construction. However, recent label changes submitted by CCA registrants will withdraw CCA from most residential applications. This action has increased interest in arsenic free preservative systems that have been standardized by the American Wood Preservers? Association. These include acid copper chromate (ACC), alkaline copper quat (ACQ), copper azole (CBA-A and CA-B), copper citrate (CC), copper dimethyldithio-carbamate (CDDC), and copper HDO (CX-A). All of these CCA alternatives rely on copper as their primary biocide, although some have co-biocides to help prevent attack by copper-tolerant fungi. These alternative treatments have appearance and handling properties‍?similar to those of CCA and are likely to be readily accepted by consumers. Prior studies indicate that these treatments release preservative components into the environment at a rate greater than or equal to that of CCA, but because their components have lower mammalian toxicity they are less likely to cause concern in residential applications. As the treated wood industry evolves, it is probable that a wider range of types and retentions of wood preservatives will become available, with the treatment more closely tailored to a specific type of construction application.

Book Synopsis Assessment of the Environmental Effects Associated with Wooden Bridges Preserved with Creosote, Pentachlorophenol, Or Chromated Copper Arsenate by : Kenneth M. Brooks
Download or read book Assessment of the Environmental Effects Associated with Wooden Bridges Preserved with Creosote, Pentachlorophenol, Or Chromated Copper Arsenate written by Kenneth M. Brooks and published by . This book was released on 2000 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timber bridges provide an economical alternative to concrete and steel structures, particularly in rural areas with light to moderate vehicle traffic. Wooden components of these bridges are treated with chromated copper arsenate type C (CCA), pentachlorophenol, or creosote to prolong the life of the structure from a few years to many decades. This results in reduced transportation infrastructure costs and increased public safety. However, the preservative used to treat the wooden components in timber bridges is lost to the environment in small amounts over time. This report describes the concentration of wood preservatives lost to adjacent environments and the biological response to these preservatives as environmental contaminants. Six bridges from various states were examined for risk assessment: two creosote treated bridges, two pentachlorophenol-treated bridges, and two CCA-treated bridges. In all cases, the largest bridges located in biologically active environments associated with slow-flowing water were selected to represent worst-case analyses. Sediment and water column concentrations of preservative were analyzed upstream from, under, and downstream from each bridge. The observed levels of contaminant were compared with available regulatory standards or benchmarks and with the quantitative description of the aquatic invertebrate community sampled from vegetation and sediments. Pentachlorophenol- and creosote-derived polycyclic aromatic hydrocarbons (PAHs) were not observed in the water near any of the selected bridges. However, low levels of PAHs were observed in the sediments under and immediately downstream from these bridges. Pentachlorophenol concentrations did not approach toxicological benchmarks. Sediment concentrations of naphthalene, acenaphthylene, and phenanthrene exceeded the probable effect level. Metal levels at the bridges treated with CCA were less than predicted effect levels, in spite of questionable construction practices. Adverse biological effects were not observed in the aquatic invertebrate community or laboratory bioassays conducted on water and sediments sampled at each of the bridges. Results of this study reveal the need to follow the construction information found in Best Management Practices for the Use of Treated Wood In Aquatic Environments published by Western Wood Preservers Institute. Regulatory benchmarks used in risk assessments of this type need to be indexed to local environmental conditions. The robust invertebrate communities associated with slow-moving streams over soft bottoms were not susceptible to the concentrations of PAHs that would be expected to affect more sensitive taxa, which typically are located in faster moving water over hard bottoms. Contaminants released from timber bridges into these faster systems (where more sensitive taxa are located) are significantly diluted and not found at biologically significant levels.
