Book Description
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.

Book Description
"The interdisciplinary conference addressed some of the most serious problems affecting sustainable development, issues that must be considered by development projects in order to provide complete solutions. A major motivation for the meeting was to learn from past failures and avoid repeating similar mistakes while attempting to prevent emerging threats to the environmental and ecological systems by developing more constructive and progressive approaches to ensure sustainability"--Publisher information.

Book Description
Wood products used in exterior applications must be protected against biodeterioration. Traditionally, wood products used CCA or the older inexpensive organic biocides, but environmental, disposal and governmental regulations have resulted in a rapid and dramatic worldwide shift. This book covers the many steps involved in developing a wood preservative and gives overviews on modified wood, wood deterioration, worldwide trends in wood protections, and mold in homes.

Book Description
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.

Book Description
This book provides a comprehensive description of traditional and innovative forest-based bioproducts, from pulp and paper, wood-based composites and wood fuels to chemicals and fiber-based composites. The descriptions of different types of forest-based bioproducts are supplemented by the environmental impacts involved in their processing, use, and end-of-life phase. Further, the possibility of reusing, recycling and upgrading bioproducts at the end of their projected life cycle is discussed. As the intensity of demand for forest biomass is currently changing, forest-based industries need to respond with innovative products, business models, marketing and management. As such, the book concludes with a chapter on the bioproducts business and these products’ role in bioeconomies.

Book Description
Containing papers presented at the 9th International Conference on Sustainable Development and Planning this volume brings together the work of academics, policy makers, practitioners and other international stakeholders and discusses new academic findings and their application in planning and development strategies, assessment tools and decision making processes. Problems related to development and planning are present in all areas and regions of the world. Accelerated urbanisation has resulted in both the deterioration of the environment and quality of life. Taking into consideration the interaction between different regions and developing new methodologies for monitoring, planning and implementation, new strategies can offer solutions mitigating environmental pollution and non-sustainable use of available resources. Energy saving and eco-friendly buildings have become an important part of modern day progress with emphasis on resource optimisation. Planning is a key part in ensuring that these solutions along with new materials and processes are efficiently incorporated. Planners, environmentalists, architects, engineers and economists have to work collectively to ensure that present and future needs are met. The papers in the book cover a number of topics, including: City planning; Regional planning; Rural developments; Sustainability and the built environment; Sustainability supply chain; Resilience; Environmental management; Energy resources; Cultural heritage; Quality of life; Sustainable solutions in emerging countries; Sustainable tourism; Learning from nature; Transportation; Social and political issues; Community planning; UN Sustainable Development Goals and Timber Structures.
