Managing Risks of Nitrates to Humans and the EnvironmentA. S. Ball, W. S. Wilson, Richard Hinton Woodhead Publishing, 1999 - 347 Seiten Nitrate levels in the environment have been the subject of intense discussion for some time. There is now a growing awareness of the need to balance the benefits and risks involved, not only in respect of nitrogenous fertilizers but also in respect of nitrate as a dietary component. Managing Risks of Nitrates to Humans and the Environment offers the latest research information on the beneficial effects of nitrates and their fate in the environment. Covering in an integrated way the agricultural, environmental and medical aspects of this emotive topic, the book confirms the sources, interactions and fate of nitrate in soils, water and the atmosphere. There is also an extensive description of the biochemistry of nitrates in plants, animals and humans, indicating the positive aspects as well as the hazards. This unique book will be applicable to a wide research audience at graduate and postgraduate level. |
