Nitrate Contamination

Nitrate Contamination PDF Author: Istvan Bogardi
Publisher: Springer Science & Business Media
ISBN: 3642760406
Category : Technology & Engineering
Languages : en
Pages : 438

Book Description
The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logists, toxicologists and environmental engineers in an integrated framework for nitrate risk management. The target readership of this book is a mix of university colleagues, practitioners from both the private and public sectors and advanced graduate students working with the hydrological, health science or environmental engineering aspects of nitrate contamination. The main conclusions include: 1. For risk assessment purposes, knowledge and sufficiently accurate models are available to predict nitrate load and its fate in water under changes in land use. 2. Once agricultural exposure controls are implemented, the response times in ground water may be so long as to make controls unrealistic. 3. It is still unknown whether agricultural best management practice is a compromise between nitrate risk reduction and agricultural revenue. 4. The current drinking water guidelines of 10 mg/L NOrN need not be changed.

Biochar for Environmental Management

Biochar for Environmental Management PDF Author: Dr. Johannes Lehmann
Publisher: Earthscan
ISBN: 1849770557
Category : Business & Economics
Languages : en
Pages : 449

Book Description
"Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.

The Ecology and Management of Wetlands

The Ecology and Management of Wetlands PDF Author: Donal D. Hook
Publisher: Springer Science & Business Media
ISBN: 1468483781
Category : Science
Languages : en
Pages : 602

Book Description
This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.

Eutrophication: causes, consequences and control

Eutrophication: causes, consequences and control PDF Author: Abid A. Ansari
Publisher: Springer Science & Business Media
ISBN: 9048196256
Category : Technology & Engineering
Languages : en
Pages : 402

Book Description
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.

Algal Ecology

Algal Ecology PDF Author:
Publisher: Academic Press
ISBN: 0080526942
Category : Science
Languages : en
Pages : 781

Book Description
Algae are an important component of aquatic benthic ecosystems because they reflect the health of their environment through their density, abundance, and diversity. This comprehensive and authoritative text is divided into three sections to offer complete coverage of the discussion in this field. The first section introduces the locations of benthic algae in different ecosystems, like streams, large rivers, lakes, and other aquatic habitats. The second section is devoted to the various factors, both biotic and abiotic, that affect benthic freshwater algae. The final section of the book focuses on the role played by algae in a variety of complex freshwater ecosystems. As concern over environmental health escalates, the keystone and pivotal role played by algae is becoming more apparent. This volume in the Aquatic Ecology Series represents an important compilation of the latest research on the crucial niche occupied by algae in aquatic ecosystems. - Presents algae as the important player in relation to environmental health - Prepared by leading authorities in the field - Includes comprehensive treatment of the functions of benthic algae as well as the factors that affect these important aquatic organisms - Acts as an important reference for anyone interested in understanding and managing freshwater ecosystems
