Download or read book Selenium Assessment in Aquatic Ecosystems written by A. Dennis Lemly and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selenium is a naturally occurring trace element that can become concentrated and released by industrial, agricultural, petrochemical and mining activities. At concentrated levels it is toxic and has polluted ecosystems around the world. This book will serve as a comprehensive practical handbook for everyone dealing with selenium in aquatic environments. It offers field-tested approaches and methods for assessment and water quality management. Using his twenty-year experience, the author discusses the effects of selenium on fish and bird populations and presents guidelines for identifying sources of pollution, interpreting selenium concentrations, assessing hazardous conditions, setting water quality criteria and ecosystem loading limits (TMDLs). He also includes a procedure for setting environmentally safe limits that ensure compliance with EPA regulations. Selenium Assessment in Aquatic Ecosystems will interest field scientists, natural resource managers, risk assessors and environmental planners.

This book was released on 2012-12-06 with total page 930 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jan van Schilfgaarde, USDA Agricultural Research Service and National Research Council Committee on Irrigation-Induced Water Quality Problems In 1982, a startling discovery was made. Many waterbirds in Kesterson National Wildlife Refuge were dying or suffering reproductive failure. Located in the San Joaquin Valley (Valley) of California, the Kesterson Reservoir (Kesterson) was used to store agricultural drainage water and it was soon determined that the probable cause of the damage to wildlife was high concen trations of selenium, derived from the water and water organisms in the reservoir. This discovery drastically changed numerous aspects of water management in California, and especially affected irrigated agriculture. In fact, the repercussions spilled over to much of the Western United States. For a century, water development for irrigation has been a religiously pursued means for economic development of the West. The primary objective of the Reclamation Act of 1902 was, purportedly, the development ofirrigation water to support family farms which, in turn, would enhance the regional economy (Worster, 1985).

Download or read book Environmental Contaminants in Wildlife written by James P. Meador and published by CRC Press. This book was released on 1996-03-20 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have been written about the effects of toxic chemicals on wildlife, but none has focused on the practical question, "How much of a chemical in the tissues of an animal is harmful?" This book deals exclusively with that question. This comprehensive reference will certainly become the standard resource on the topic, offering authoritative and sound advice on many environmental contaminants. With chapters written by outstanding experts in their respective fields, this is not only a scholarly collection of discussions on different chemicals, but, for those who have the day-to-day task of evaluating the harm of environment contaminants to wildlife, this book will provide answers on, for example, how to interpret 1 ppm lead in the liver of a duck or fish. The authors explain the snags of interpreting data that are sometimes conflicting or insufficient, providing the reader with helpful advice on how to cope with such data. Each chapter reviews literature on a specific chemical, followed by a easy-to-understand summary providing technical guidance. For many years this book will remain the preeminent reference on how to interpret contaminant levels of organochlorine pesticides, PCBs, dioxins, PAHs, metals, selenium, and fluorides in wildlife.
