Book Description
River Pollution 2: Causes and Effects deals mainly with the causes of river pollution and the nature of the various kinds of pollution and their effects upon rivers. This book is an updated version of the first eight chapters of Aspects of River Pollution (first published early in 1957). Owing to the rapid development of the subject and the ever-increasing amount of literature devoted to it, some sections have been virtually rewritten, much new matter has been added, and minor alterations made throughout the text. This book begins with a review of the long history of river pollution, which can be traced back to ancient civilizations. Separate chapters deal with legal aspects of river pollution; the nature and effects of river pollution; the causes of river pollution; and uses of river water. Subsequent chapters cover the biochemical and physicochemical aspects of river pollution; the impact of river pollution on fishes; and biological aspects of river pollution.

Book Description
Over the past 50 years, triazines have made a great impact on agriculture and world hunger by assisting in the development of new farming methods, providing greater farming and land use capabilities, and increasing crop yields. Triazines are registered in over 80 countries and save billions of dollars a year. The Triazine Herbicides is the one book that presents a comprehensive view of the total science and agriculture of these chemicals. With emphasis on how the chemicals are studied and developed, reviewed, and used at the agricultural level this book provides valuable insight into the benefits of triazine herbicides for sustainable agriculture. - Presents previously unpublished information on the discovery, development and marketing of herbicides - Includes a vital section on the origin, use, economics and fate of triazine herbicides - Covers benefits of triazines in corn and sorghum, sugarcane, citrus, fruit and nut crops - Establishes best management practice and environmental benefits of use in conservation tillage

Book Description
Metal Poisoning in Fish provides a comprehensive look at many aspects of metal poisoning of euryhaline and stenohaline fish. Metals and metalloids are considered individually and collectively and include arsenic, lead, selenium, copper, cadmium, mercury, and zinc. This informative, readable volume is designed to help regulatory personnel, enforcement personnel, and scientists understand the impact of these elements on fish. Topics covered include mechanisms of action, toxicity, biological effects, accumulation, tissue distribution, concentration factors, maximum acceptable toxicant concentrations, application factors, biological half-lives, uptake kinetics, depuration kinetics, elemental speciation, and detoxification mechanisms. The book emphasizes the use of data gathered from a variety of sources to pinpoint specific elemental agents as causal factors in the morbidity and mortality of fish.
