Available in PDF, EPUB and Kindle. Book excerpt: "Mercury deposition and contamination is widespread and well documented, and it continues to be a public-health concern for certain sectors of the global human population in both developed and developing countries. This edited volume focuses on integrating the diverse sciences involved in the process of mercury cycling in the environment--from the atmosphere, through terrestrial and aquatic food webs, and human populations--to develop a comprehensive perspective on this important environmental pollutant. Using a systems-level approach, this book provides recommendations on mercury remediation, risk communication, education, and monitoring. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly, expanding into several interdisciplinary fields and encompassing such disparate academic and scientific disciplines as biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists really begun to establish more holistic approaches to studying mercury pollution, giving rise to investigations that have furthered the integration of a multi-tiered approach, especially by using chemistry, biology, and human health sciences collectively. The study of mercury pollution has produced a variety of contributions to domestic and international policies related to the management of mercury in the environment"-- Provided by publisher.

Download or read book Mercury in Fish Bed Sediment and Water from Streams Across the United States 1998 2005 written by Barbara C. Scudder and published by DIANE Publishing. This book was released on 2010-08 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report on how mercury (Hg) was examined in top-predator fish, bed sediment, and water from streams that spanned regional and national gradients of Hg source strength and other factors thought to influence methylmercury bioaccum. Sampled settings include stream basins that were agr¿l, urbanized, undeveloped, and mined. Predator fish were targeted for collection, and composited samples of fish were analyzed for total Hg (THg), as most of the Hg found in fish tissue is MeHg. Samples of bed sediment and stream water were analyzed for THg, MeHg, and characteristics thought to affect Hg methylation, such as loss-on-ignition and acid-volatile sulfide in bed sediment, and pH, dissolved organic carbon, and dissolved sulfate in water.

This book was released on 2015-10-05 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem effects from air pollution in the Adirondacks, Catskills, and elsewhere in New York have been substantial. Efforts to characterize and quantify these impacts, and to examine more recent recovery, have focused largely on surface waters, soils, and forests. Lakes, streams, and soils have acidified. Estuaries have become more eutrophic. Nutrient cycles have been disrupted. Mercury has bioaccumulated to toxic levels. Plant species composition has changed. Some surface waters show signs of partial chemical recovery in response to emissions control programs, but available data suggest that soil chemistry may continue to deteriorate under expected future emissions and deposition. Resource managers, policymakers, and scientists now need to know the extent to which current and projected future emissions reductions will lead to ecosystem recovery.In this book, Timothy J. Sullivan provides a comprehensive synthesis of past, current, and potential future conditions regarding atmospheric sulfur, nitrogen oxides, ammonium, and mercury deposition; surface water chemistry; soil chemistry; forests; and aquatic biota in New York, providing much needed information to help set emissions reduction goals, evaluate incremental improvements, conduct cost/benefit analyses, and prioritize research needs. He draws upon a wealth of research conducted over the past thirty years that has categorized, quantified, and advanced understanding of ecosystem processes related to atmospheric deposition of strong acids, nutrients, and mercury and associated ecosystem effects. An important component of this volume is the new interest in the management and mitigation of ecosystem damage from air pollution stress, which builds on the "critical loads" approach pioneered in Europe and now gaining interest in the United States.This book will inform scientists, resource managers, and policy analysts regarding the state of scientific knowledge on these complex topics and their policy relevance and will help to guide public policy assessment work in New York, the Northeast, and nationally.

Download or read book Air Pollution and Its Impacts on U S National Parks written by Timothy J. Sullivan and published by CRC Press. This book was released on 2017-02-03 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the management of surface water and groundwater resources.

Download or read book Stream Ecology written by J. David Allan and published by Springer Nature. This book was released on 2021-03-17 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream Ecology: Structure and Function of Running Waters is designed to serve as a textbook for advanced undergraduate and graduate students, and as a reference source for specialists in stream ecology and related fields. This Third Edition is thoroughly updated and expanded to incorporate significant advances in our understanding of environmental factors, biological interactions, and ecosystem processes, and how these vary with hydrological, geomorphological, and landscape setting. The broad diversity of running waters – from torrential mountain brooks, to large, lowland rivers, to great river systems whose basins occupy sub-continents – makes river ecosystems appear overwhelming complex. A central theme of this book is that although the settings are often unique, the processes at work in running waters are general and increasingly well understood. Even as our scientific understanding of stream ecosystems rapidly advances, the pressures arising from diverse human activities continue to threaten the health of rivers worldwide. This book presents vital new findings concerning human impacts, and the advances in pollution control, flow management, restoration, and conservation planning that point to practical solutions. Reviews of the first edition: ".. an unusually lucid and judicious reassessment of the state of stream ecology" Science Magazine "..provides an excellent introduction to the area for advanced undergraduates and graduate students..." Limnology & Oceanography "... a valuable reference for all those interested in the ecology of running waters." Transactions of the American Fisheries Society Reviews of the second edition: "Overall, a must for the field centre and a good starter text in stream ecology." (TEN News, October, 2007) "Highly recommended. Upper-division undergraduates through faculty." (P. R. Pinet, CHOICE, Vol. 45 (7), 2008) "... a very good, fluidly readable book which contains the latest key scientific knowledge of the ecology of running waters."
