Sources, Fate, and Transport of Nitrogen and Phosphorus in the Chesapeake Bay Watershed

Category : Chesapeake Bay Watershed
Languages : en
Pages : 27
Book Description
Spatially Referenced Regression on Watershed Attributes (SPARROW) was used to provide empirical estimates of the sources, fate, and transport of total nitrogen (TN) and total phosphorus (TP) in the Chesapeake Bay watershed, and the mean annual TN and TP flux to the bay and in each of 80,579 nontidal tributary stream reaches. Restoration efforts in recent decades have been insufficient to meet established standards for water quality and ecological conditions in Chesapeake Bay. The bay watershed includes 166,000 square kilometers of mixed land uses, multiple nutrient sources, and variable hydrogeologic, soil, and weather conditions, and bay restoration is complicated by the multitude of nutrient sources and complex interacting factors affecting the occurrence, fate, and transport of nitrogen and phosphorus from source areas to streams and the estuary. Effective and efficient nutrient management at the regional scale in support of Chesapeake Bay restoration requires a comprehensive understanding of the sources, fate, and transport of nitrogen and phosphorus in the watershed, which is only available through regional models. The current models, Chesapeake Bay nutrient SPARROW models, version 4 (CBTN_v4 and CBTP_v4), were constructed at a finer spatial resolution than previous SPARROW models for the Chesapeake Bay watershed (versions 1, 2, and 3), and include an updated timeframe and modified sources and other explantory terms.

Book Description
Chemical Fate and Transport in the Environment, Fourth Edition explains the fundamental principles of mass transport, chemical partitioning, and chemical/biological transformations of pollutants and naturally occurring chemicals in surface waters, in the subsurface (which includes soil and groundwater), and in the atmosphere. Each of these three major environmental media is introduced by a descriptive overview, followed by presentations of the governing physical, chemical, and biological processes. The text emphasizes intuitively based mathematical models for chemical equilibria, transformations, and transport in the environment. This book serves as a primary text for graduate and senior undergraduate courses in environmental science and engineering, provides relevant scientific knowledge for students of public health and environmental policy, and is a useful reference for environmental practitioners. This fourth edition builds on the third edition, which won a 2015 Textbook Excellence Award (Texty) from The Text and Academic Authors Association. This updated textbook expands the discussion of global climate change, presents concepts of stationarity and sustainability, provides additional coverage of wastewater treatment and air pollution abatement technologies, and includes information on additional anthropogenic pollutants such as plastics, PFAS, and nanoparticles. Tables, figures, and references are updated, and worked examples and practice exercises are included for each chapter. - Illustrates the interconnections, similarities, and contrasts among three major environmental media: surface waters, the subsurface (which includes soil and groundwater), and the atmosphere - Discusses and builds upon fundamental concepts, teaching students to realistically address environmental problems and preparing students for more advanced studies - Each chapter includes many worked examples and extensive practice exercises; a solutions manual is available for instructors
Nitrogen Overload

Pages : 304
Book Description
Finalist for the 2021 PROSE Award for Environmental Science! An integrated approach to understanding and mitigating the problem of excess nitrogen Human activities generate large amounts of excess nitrogen, which has dramatically altered the nitrogen cycle. Reactive forms of nitrogen, especially nitrate and ammonia, are particularly detrimental. Given the magnitude of the problem, there is an urgent need for information on reactive nitrogen and its effective management. Nitrogen Overload: Environmental Degradation, Ramifications, and Economic Costs presents an integrated, multidisciplinary review of alterations to the nitrogen cycle over the past century and the wide-ranging consequences of nitrogen-based pollution, especially to aquatic ecosystems and human health. Volume highlights include: Comprehensive background information on the nitrogen cycle Detailed description of anthropogenic nitrogen sources Review of the environmental, economic, and health impacts of nitrogen pollution Recommendations and strategies for reducing humanity's nitrogen footprint Discussion of national nitrogen footprints and worldwide examples of mitigation policies The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

The European Nitrogen Assessment

ISBN: 1139501372
Category : Science
Languages : en
Pages : 665
Book Description
Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.
