Eutrophication, the excessive enrichment of waters with nutrients and the associated adverse biological effects, is one of the major environmental problems across Europe. European waters are affected across the whole range from inland water bodies such as groundwater, rivers and lakes, to transitional and coastal waters and ecosystems in open seas. Eutrophication is caused by large anthropogenic inputs of the nutrients nitrogen (N) and phosphorus (P) to the aquatic environment from a range of societal sectors. This study primarily focuses on the contribution of agriculture to this contamination.

This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

The latest thinking and research on nutrients have been brought together by experts in the chemical and biological sciences and in engineering. The authors represent educational institutions, government, and industry. The book features a broad discussion of the topic. In addition to chapters on the three principal nutrients (nitrogen, phosphorus, and carbon), chapters on nutrient geochemistry and nutrient regeneration in hypolimnetic waters are included. Both chemical and bioassay analyses of nutrients are discussed by experts in their respective fields. Computer models of nutrient biochemical processes are described with the use of many illustrations, so that even those unfamiliar with computer techniques can appreciate their utility.

Phosphorus in Fresh Water and the Marine Environment investigates sources of phosphorus in fresh water and the marine environment and the problems it causes. The importance of phosphate precipitation as an inbuilt safety device against overproduction of algae in the oceans is discussed, along with the deposition and absorption of phosphates in sediments. The source of the phosphorus in lakes and rivers is considered in relation to population density and distribution. This book is comprised of 26 chapters and begins with a discussion on natural phosphate sources in relation to phosphate budgets, paying particular attention to eutrophication and soil erosion. The significance of man-made sources of phosphorus, such as fertilizers and farming, detergents and sewage, is then examined. Subsequent chapters focus on the role of phosphorus in the growth of plants and animals in rivers, lakes, and the sea; the hydrogeochemical cycling of phosphorus; phosphorus analysis in sea water; and safety evaluation of substitutes for phosphates in detergents. The microbiology of an activated sludge wastewater treatment plant chemically treated for phosphorus removal is also explored. This monograph will be of interest to policymakers concerned with water pollution control.

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.
