Werner Stumm Volgorde van de boeken (chronologisch)

Aquatic systems play a salient role in the complex processes of energy and matter exchange between the geosphere and the atmosphere. For example, reactions taking place in cloud water droplets can substantially alter the atmospheric budget and chemistry of trace gases; pollution induced weathering reactions at water/soil interfaces can affect the availability of nutrients and increase the concentration of potentially toxic metals in groundwaters. Moreover, the inextricable links between the water cycle, the geosphere and the atmosphere ensure that apparently localized environmental problems have increasingly impacts in other parts of the world. To identify local-to-global scale variables associated with environmental changes, a focus must be placed on the recognition of processes, rather than a continued reliance on monitoring state variables. However, in heterogeneous aquatic systems, small scale aspects of a process under observation may not be summed directly to obtain regional estimates because of process nonlinearities with change in scale. To understand this, the integrated use of measurements across a range of scales is required.

Examines a theoretical basis for the chemical behavior of ocean waters, estuaries, rivers, lakes, groundwaters, and soil water systems. Covers the processes involved in water treatment, comparing real systems with idealized counterparts or models. Discusses chemical processes affecting the distribution and circulation of chemical substances with an ecological perspective on pollution and its control. Also shows the application of elementary principles of physical chemistry, the interplay of chemical equilibria and kinetic considerations, in isolating and identifying some of the variables which affect the composition of the water. Includes numerous graphs and illustrations.

A text for an interdisciplinary environmental course that identifies the physical and chemical properties that determine environmental behavior, describes the processes in the natural environment that can be effective in transforming chemicals, and defines the molecular characteristics that can cause a particular compound to react in those processes.
