Book excerpt: Recent research on the release of wood preservatives from treated wood used in sensitive environments has not considered the potential contribution from construction residues. This study sought to develop leaching rate data for small construction debris and compare those to the release rate from treated wood itself. Western hemlock boards were pressure treated with chromated copper arsenate Type C (CCA-C), and then common construction tools were used to generate sawdust or shavings from those boards. These wood particles were then leached in deionized water, and the leaching rate was compared with that of solid wood samples cut from the same specimen. Release rate data from this study were also compared with those from endmatched samples that were leached in artificial rain in an earlier study. The release rates of copper, chromium, and arsenic from CCA-C treated chain saw sawdust, circular saw sawdust, and spade bit shavings were many times higher than from solid wood when samples were immersed in water. There was little difference in the release rates among the three types of shavings and sawdust, despite differences in their particle sizes. The rates of release from decking exposed to rainfall were many times lower than that of construction debris or solid wood continually immersed in water. These results show the importance of minimizing the amount of construction debris that is allowed to enter the aquatic environment. However, example calculations also demonstrate that if reasonable efforts are made to minimize release of construction debris, the contribution of these particles to the overall release of preservative from the structure will be minimal.

Book Synopsis The Informed Gardener Blooms Again by : Linda Chalker-Scott
Download or read book The Informed Gardener Blooms Again written by Linda Chalker-Scott and published by University of Washington Press. This book was released on 2013-02-28 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Informed Gardener Blooms Again picks up where The Informed Gardener left off, using scientific literature to debunk a new set of common gardening myths. Once again, Linda Chalker-Scott investigates the science behind each myth, reminding us that urban and suburban landscapes are ecosystems requiring their own particular set of management practices. The Informed Gardener Blooms Again provides answers to questions such as: Does using drought-tolerant plants reduce water consumption? Is it more effective to spray fertilizers on the leaves of trees and shrubs than to apply it to the soil? Will cedar wood chips kill landscape plants? Should I use ladybugs in my garden as a form of pest control? Does aerobically brewed compost tea suppress disease? Every year Chalker-Scott receives hundreds of e-mails from around the world on these and related topics. Her advice, based on more than twenty years of experience in the field of plant physiology, has helped home gardeners, landscape architects, and nursery and landscape professionals to develop scientifically based sustainable landscaping practices.

Book Synopsis Field Evaluation of Timber Preservation Treatments for Highway Applications by : Jake J. Bigelow
Download or read book Field Evaluation of Timber Preservation Treatments for Highway Applications written by Jake J. Bigelow and published by . This book was released on 2007 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Timber material repair and replacement cost for timber bridges is a considerable expense to highway agencies in Iowa, especially to county road departments. To address these needs, the objectives of this investigation was to study the field effectiveness of various treatment alternatives used on Iowa roadway projects and to determine if the current specifications and testing are adequate for providing proper wood preservation. To satisfy the research needs, the project scope involved a literature review, identification of metrics, questionnaire survey of Iowa counties, on site inspections, and a review of current specifications and testing procedures. Based on the preservative information obtained, the following general conclusions were made: Copper naphthenate is recommended as the plant-applied preservative treatment for timber bridges. Best Management Practices should be followed to ensure quality treatment of timber materials. Bridge maintenance programs need to be developed and implemented. The Iowa Department of Transportation specifications for preservative treatment are the regulating specification for bridges constructed with state or federal funding in Iowa and are also recommended for all other bridges.

Book Synopsis Environmental Impacts of Treated Wood by : Timothy G. Townsend
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 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the extensive use of treated wood products throughout urban and agricultural communities, information concerning the environmental and health risks associated with treated wood is very much in demand. Responding to increasing need for a comprehensive and cohesive source on this topic, Environmental Impacts of Treated Wood compiles the latest information concerning regulations, environmental impact studies, new wood preservative formulations, and state-of-the-art disposal technologies available for minimizing environmental impacts caused by treated wood. Beginning with a background of the production of the most common treated wood products, this book discusses how chemical leaching and transport of certain wood preservatives affect the environment, particularly chromated copper arsenate. A separate section is devoted to case studies that evaluate possible links with cancer and other health risks with repeated exposure to treated wood. Several chapters discuss ways to measure exposure and review various approaches to risk assessment and management. Because treated wood products last a long time, the book also considers the disposal of treated wood in terms of human and environmental impact. It explores novel disposal technologies and practical strategies for complying with regulatory phase-outs of certain treated wood products within the U.S., Canada, Europe, Australia, and many Asian countries. These include recycling, bioremediation, thermal treatment, and landfills. Environmental Impacts of Treated Wood provides a timely compilation of perspectives necessary for making informed, conscientious decisions in the production, use, and disposal of treated woods that will minimize the environmental impact and human exposure risks associated with treated wood products today.
