Book Description
This report represents the first national assessment of PBDEs in the U.S. coastal zone. Results suggest that they are widely distributed nationally. Several regions, including the northern Mid-Atlantic, central Gulf of Mexico, Southern California, Pacific Northwest and the Great lakes have elevated PBDE concentrations compared with other coastal regions. Furthermore, PBDE concentrations are positively correlated with human population density along the U.S. coastline. The national and regional perspectives provided herein are intended to support research, local monitoring, and to assist resource managers and policy makers tasked with making regulatory decisions about these contaminants.

Book Description
Environmental pollution by man-made persistent organic chemicals (POCs) has been a serious global issue for over half a century. POCs are prevalent in air, water, soil, and organisms including wildlife and humans throughout the world. They do not degrade and cause long-term effect in organisms. Exposure to certain POCs may result in serious environmental and health effects including birth defects, diminished intelligence and certain types of cancers. Therefore, POCs have been the subject of an intensive regional, national and international effort to limit their production, use, and disposal of these chemical stocks. Trend monitoring studies are essential to make clear the behavior and fate of these compounds and to protect our environment and living resources. Global Contamination Trends of Persistent Organic Chemicals provides comprehensive coverage of spatial and temporal trends of classical and emerging contaminants in aquatic, terrestrial, and marine ecosystems, including the Arctic and Antarctic ecosystems. Compiled by an international group of experts, this volume covers: Spatial and temporal trends of polychlorinated biphenyls (PCBs), chlorinated pesticides, polychlorinated naphthalenes (PCNs), polychlorinated dibenzo-p-dioxins/furans (PCDD/DFs), polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs), perfluorinated compounds (PFCs), synthetic musks, polynuclear aromatic hydrocarbons (PAHs), and octyl- and nonylphenols Environmental and biological matrices used for the trend studies were atmosphere, water, soil, sediment, bivalve mollusks, fish, marine mammals, terrestrial mammals, and human breast milk Spatial and temporal trend studies presented from Australia, Brazil, China, Estonia, Ghana, Hong Kong, India, Italy, Japan, Korea, Norway, Poland, Sweden, the United States, coastal and open ocean environments, and the Arctic and Antarctic regions POCs have been the subject of an intensive regional, national, and international effort to limit their production and use, and to mitigate the disposal of these chemicals. Since POCs are prevalent in air, water, soil, and tissues of organisms (including wildlife and humans) throughout the world and do not degrade, they cause long-term effects in organisms. Trend monitoring studies are essential to make clear the behavior and fate of these compounds and to protect our environment and living resources. Relevant to professionals and students alike, Global Contamination Trends of Persistent Organic Chemicals facilitates the understanding of environmental and biological behavior of these chemicals and the development of strategies for protecting the global environment for future generations.

Book Description
Polymer matrix composites (PMCs) have been used extensively in the marine industry because of their attractive properties, including light weight, high stiffness-to-weight and strength-to-weight ratios, ease of installation on the field, high overall durability, and less susceptibility to environmental deterioration than conventional materials. However, due to their organic nature, PMCs will degrade, decompose, and yield smoke and toxic gases when subjected to fire, leading to catastrophic consequences. Therefore, the primary focus of this chapter is on the fire safety issues of PMCs and methods to improve the fire safety for marine applications. To improve these materials’ flame-retardant performance, traditional flame retardants are reviewed, including halogenated, intumescent, and intrinsic flame retardants. The flame-retardant application of nanomaterials such as nanoclay, carbon nanotubes, and polyhedral oligomeric silsesquioxane is then introduced. Finally, the concept of hybrid flame-retardant nanocomposite coating is presented. It is concluded that a desirable flame-retardant coating system should have such necessary characteristics, including low thermal conductivity in the thickness direction to prevent heat transfer, high in-planar thermal conductivity to dissipate heat as soon as possible, high thermal stability and heat capacity, low heat absorption, and compact char structure to prevent mass loss.

Book Description
The U.S. Ocean Commission Report identified the need for regional ecosystem assessments to support coastal and ocean management. These assessments must provide greater understanding of physical and biological dynamics than assessments at global and national scales can provide but transcend state and local interests. This need and timeliness is apparent for Long Island Sound, where a multi-state regional restoration program is underway for America’s most urbanized estuary. Synthesis of the Long Island Sound ecosystem is needed to integrate knowledge across disciplines and provide insight into understanding and managing pressing issues, such as non-point sources of pollution, coastal development, global climatic change, and invasive species. Currently, there is a need for a comprehensive volume that summarizes the ecological and environmental dynamics and status of Long Island Sound and its myriad ecosystems. It has been 30 years since a comprehensive summary of Long Island Sound was prepared and 50 years since the pioneering work of Gordon Riley. Major advances in estuarine science are providing new insights into these systems, and yet, the condition of many estuaries is in decline in the face of continuing coastal development. There is an opportunity to lay a foundation for integrative coastal observing systems that truly provide the foundation for improved decision-making. This book will provide a key reference of our scientific understanding for work performed over the past three decades and guide future research and monitoring in a dynamic urbanized estuary.

Book Description
This long-anticipated reference and sourcebook for California’s remarkable ecological abundance provides an integrated assessment of each major ecosystem type—its distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of California’s ecological patterns and the history of the state’s various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the state’s ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of California’s environment and curious naturalists.
