Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.

Revolving around the principles of sustainability, this new edition sets out to provide students with a balanced, complete treatment of environmental issues - their scientific basis, history and future. Material is revised to reflect changing environmental understanding and issues.

Eutrophication is a problem which became widely recognised by the scientific community in the 1940s and 1950s. It raised public concern, resulting in increased research effort and expenditure on management techniques through the 1960s and 1970s, recognised as a distinct problem of water pollution, though linked with the more gross effects of organic pollution. In the 1980s it became less fashionable - replaced in the public's eye and the politician's purse by newer problems such as acid rain. It remains however, one of the biggest and most widespread problems of fresh waters, particularly of lakes and an increasing problem for estuaries and coastal waters. It is one with which almost all water scientists and engineers in urbanised areas of the world have to cope. Technical methods for the reversal of eutrophication, such as nutrient removal, have been developed and applied successfully in some instances. They are not widespread however, and where they are feasible, they are often expensive and may be politically difficult to implement. In the last decade, attention has focussed upon less expensive lake manipula tion techniques, such as destratification and biomanipulation, which aim to minimise rather than elimininate the detrimental effects of eutrophication. These are becoming more widely applied. Prediction of the potential problems in lakes and catchments which have not yet suffered the full effects of eutrophication is now accurate enough to be of direct benefit to river basin management.

A clear, straightforward presentation of concepts and issues in aquatic pollution This comprehensive introductory text presents a systematic study of pollution in oceans, lakes, streams, and underground aquifers. In a clear, straightforward style that is easily accessible to nonscientists, it describes the sources, features, and effects of thirteen different types of aquatic pollution. Fully updated to reflect current understanding and recent developments, this Third Edition of Aquatic Pollution covers every aspect of pollution associated with urban runoff, acid rain, sewage disposal, pesticides, oil spills, nutrient loading, and more. Case studies of major pollution sites such as Lake Erie, Three Mile Island, and the Rocky Mountain Arsenal help to illustrate points made in the general discussion. Important features of this new edition include: * Updated discussions of nonpoint source pollution, industrial pollution, thermal pollution, pathogens, metals, plastics, and more * New case studies of Chesapeake Bay and the Exxon Valdez * Beginning-of-chapter outlines * End-of-chapter study questions * New special section on units of measurement * Four chapters on the fundamentals of ecology and toxicology Aquatic Pollution, Third Edition, is a first-rate teaching and learning tool for courses in environmental science, zoology, oceanography, biology, and civil or sanitary engineering. It is also an excellent primer for policymakers and activists focused on environmental issues.

For many years the reduction of eutrophication in the Baltic Sea has been a hot issue for mass-media, science, political parties and environmental action groups with manifold implications related to fisheries (will the Baltic cod survive?), sustainable coastal development (have billions of Euros been wasted on nitrogen reductions?), ecotoxicology (can we safely eat Baltic fish?). This book takes a holistic process-based ecosystem perspective on the eutrophication in the Baltic Sea, with a focus on the factors regulating how the system would respond to changes in nutrient loading. This includes a very special process for the Baltic Sea: land uplift. After being depressed by the glacial ice, the land is now slowly rising adding vast amounts of previously deposited nutrients and clay particles to the system. 110,000 to 140,000 tons of phosphorus per year are added to the system from land uplift, in comparison to the 30,000 tons of phosphorus per year from rivers.

With all new and updated material, the third edition provides civil engineers with a complete history of water availability. It also delves into government development, management, and policy of water usage. New information is included on international water issues, water measurement, and telemetry. Additional details are also presented on global warming and its impact on water resources. In addition, environmental engineers will gain a current understanding of the field through updated case studies and images that make the material more relevant.
