Available in PDF, EPUB and Kindle. Book excerpt: The effective and lasting treatment of wood against insect and fungal attack grows in importance as forestry reserves decline and as cost increases feed through to the building trade and other timber users. At the same time, environmental pressures bear ever more heavily on the types of chemicals and processes employed in the preservation industry. This book records the proceedings of an international meeting arranged to address such issues. The 15 principal chapters are based upon papers by invited experts to a combined audience of preservation practitioners and non-specialists. The chapter sequence follows the logical pattern of the conference, beginning with a review of the biological threats to be contended. There follow historical and state-of-the-art accounts of aqueous, organic solvent and non-liquid treatment processes. Preservatives increasingly must meet international product and environmental standards, which along with the related test, analytical and quality control procedures, are described and referenced. Contributors from the wood preservation industry address a range of needs associated with cost, safety and performance efficacy, not neglecting a search for a better understanding of the finer chemical mechanisms involved. Remaining problems are outlined in strategies for further research and development. - Address a range of needs associated with cost, safety and performance efficacy - Problems are outlined in strategies for further research and development
Download or read book Environmental Impacts of Treated Wood written by Timothy G. Townsend and published by CRC Press. This book was released on 2006-06-02 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Responding to a heightened awareness of the possible adverse effect of treated wood, this book presents multidisciplinary research results and fundamental information on regulations, wood treatment alternatives, and documentation of environmental releases. It examines the impact of treated wood on water, soil, and organisms. Several chapters discuss ways to measure exposure and review various approaches to risk assessment and management. Case studies address human health effects of exposure. The book also presents state-of-the-art disposal technologies, new preservative compounds, and recent developments related to phase outs of certain treated wood products.

Download or read book Environmental Impact of Wood Preservative Leachates written by Silvija Stefanovic and published by . This book was released on 2006 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood preservatives are used to protect wood products from decay to prolong their effective service life. Due to health and environmental concerns, one of the preservatives with very effective protective characteristics, CCA (chromated copper arsenate), was phased out for residential use and slowly replaced by alternatives such as ACQ (alkaline copper quaternary) and CA (copper azole). While it is assumed that these new preservatives have lower health and environmental impacts than CCA, relatively little work has been done to assess the leaching characteristics and eco-toxicity effects of these preservatives. Depending on the physical and chemical characteristics of soil, adsorption of inorganic components of leachates from preservative treated wood can limit movement of contaminants to other compartments (soil as a "sink") and reduce their toxic effect by limiting bioavailability. Estimated adsorption maxima of Cu CCA in organic and clay soils were the same or higher than for Cu ACQ and Cu CA. However, soil has a limited capacity for adsorption and after long exposure to slight contamination this capacity could be exceeded resulting in more widespread impacts. There was much higher leaching of Cu from ACQ and CA treated wood than from CCA treated samples indicating that ACQ treated wood may result in higher risk to aquatic organisms. CCA components were more effectively bound in soil than copper from copper amine systems. Coating treatments reduced leaching of all elements from 32 to 91 % and identification of appropriate coating systems will result in the potential to reduce impacts of preservative leachates. The presence of preservative components in the soil decreased the yield and increased their accumulation in ryegrass. Uptake of As, Cu, and Cr in rye grass was just as well predicted by total soil content as with any of the "bioavailable" estimates. ACQ leachate showed higher toxicity to germination of ryegrass seeds and Daphnia magna toxicity; it had a lower effect on ryegrass growth than CCA leachate. Reaction of ACQ leachate with sandy soil components resulted in reduced toxicity to Daphnia magna . None of the contaminated soils had a measurable effect on earthworms, although there was some preservative uptake in the worms. CCA and ACQ had similar effects on soil microflora/fauna respiration. CA leachate had lower toxicity to Daphnia magna and similar toxicity to other organisms as ACQ.
