Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Download or read book Sources Fate and Transport of Nitrogen and Phosphorus in the Chesapeake Bay Watershed written by Scott W. Ator and published by Geological Survey (USGS). This book was released on 2011 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Interactions of C N P and S Biogeochemical Cycles and Global Change written by Roland Wollast and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a natural extension of the SCOPE (Scientific Committee of Problems on the Environment) volumes on the carbon (C), nitrogen (N), phosphorus (P) and sulfur (S) biogeochemical cycles and their interactions (Likens, 1981; Bolin and Cook, 1983). Substantial progress in the knowledge of these cycles has been made since publication of those volumes. In particular, the nature and extent of biological and inorganic interactions between these cycles have been identified, positive and negative feedbacks recognized and the relationship between the cycles and global environmental change preliminarily elucidated. In March 1991, a NATO Advanced Research Workshop was held for one week in Melreux, Belgium to reexamine the biogeochemical cycles of C, N, P and S on a variety of time and space scales from a holistic point of view. This book is the result of that workshop. The biogeochemical cycles of C, N, P and S are intimately tied to each other through biological productivity and subsequently to problems of global environmental change. These problems may be the most challenging facing humanity in the 21 st century. In the broadest sense, "global change" encompasses both changes to the status of the large, globally connected atmospheric, oceanic and terrestrial environments (e. g. tropospheric temperature increase) and change occurring as the result of nearly simultaneous local changes in many regions of the world (e. g. eutrophication).

Available in PDF, EPUB and Kindle. Book excerpt: Universal access to safe drinking water and sanitation in a manner that protects human health and the environment are key development and welfare issues. Water resources vary greatly throughout Europe and within regions, and future water availability is likely to be influenced by a number of factors including climate change, especially in coastal areas. This joint report by the European Environment Agency and the World Health Organisation Regional Office for Europe highlights the state of Europe's water resources, their health implications, and policy initiatives to address these issues. Aspects considered include: drinking and recreational water quality; health impacts such as waterborne diseases and sanitation; irrigation, industrial and agricultural practices; and water pollution.

Download or read book Wind Borne Illness from Coastal Seas written by John J Walsh and published by Academic Press. This book was released on 2019-07-18 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind-Borne Illness from Coastal Seas: Present and Future Consequences of Toxic Marine Aerosols explores the present and future human health consequences of marine aerosol poisons carried ashore by coastal winds. The book compiles relevant information on an interrelated toxicological, environmental sciences and public health problem that is combined with recent observations, extensive epidemiological data and case studies. It tackles this challenge with a small, interdisciplinary group of authors who dissect the underlying causes and potential remedies of increasing ill health issues on a planet that is covered by 70% seawater and subject to increasing sea spray-containing malign aerosols. The book's authors outline the historical context of the situation, discuss the importance of recognizing toxic marine aerosols as a cause of wind-borne illness, and suggest operational forecasts for avoidance of onshore, wind-borne marine toxins, and crucially, present extensive epidemiological evidence. This resource will be useful to a wide variety of toxicologists, medical doctors and environmental scientists. - Contains extensive epidemiological data and case studies on aerosol forms of windborne global marine toxins - Presents information from an interdisciplinary author team - Argues for future operational forecasts for avoidance of onshore, windborne marine toxins
