Refractory Organic Substances in the Environment

Die Ergebnisse von langjähriger und hochkarätiger Forschung auf dem Gebiet der Refrakträren Organischen Substanzen (ROS), auch als Huminstoffe bezeichnet, sind in diesem Buch dargestellt. Es bietet eine umfassende Behandlung der Strukturen, der Eigenschaften und der Wechselwirkungen dieser Substanzklasse im Hinblick auf ihr Umweltverhalten, sowohl unter chemischen wie unter biologischen Aspekten. Refraktäre Organische Substanzen spielen sowohl in den Agrarwissenschaften, der Bodenkunde, der Wasserversorgung wie im Umweltschutz eine wichtige Rolle.Das Buch zeichnet sich insbesondere durch folgende Themen aus:- Entwicklung und Anwendung von Referenzmaterialien für ROS- Biologische und molekulare Wechselwirkungen als Faktoren der Charakterisierung- Leistungsfähige analytische Methoden, insbesondere NMR- und MS-TechnikenEs enthält viele Tabellen und Abbildungen mit nützlichen Daten.
