Organic matter mineralization

As shown in Fig. 3, CHEMGL considers 10 major well-mixed compartments air boundary layer, free troposphere, stratosphere, surface water, surface soil, vadose soil, sediment, ground water zone, plant foliage and plant route. In each compartment, several phases are included, for example, air, water and solids (organic matter, mineral matter). A volume fraction is used to express the ratio of the phase volume to the bulk compartment volume. Furthermore, each compartment is assumed to be a completely mixed box, which means all environmental properties and the chemical concentrations are uniform in a compartment. In addition, the environmental properties are assumed to not change with time. Other assumptions made in the model include continuous emissions to the compartments, equilibrium between different phases within each compartment and first-order irreversible loss rate within each compartment [38].

The water-rock/soil and organic matter-minerals (including soil organic matter-clay), interactions can also be studied by infrared spectroscopy (Chapter 2, Section 2.1.2).

Potential processes that may be called upon to explain the large discrepancy between excess N2 and NOs deficits within the SNM are (1) sedimentary denitrification, (2) anammox, (3) metal (Fe, Mn)-catalyzed denitrification, and (4) non-Redfieldian organic matter mineralization (Codispoti et al., 2001 Devol et al., 2006a,b). The first of these possibilities requires a decoupling between nitrogen and phosphorus cycles (e.g. possible greater burial of phosphorus in continental margin sediments). The less likely additional requirement is that the maximal inputs from the sediments should occur at the same depth as the water column peak of N02. In other words, the exact coincidence of the extrema in NOs , N02, ...

The determination of distribution pattern of various forms of both macroelements and trace metals in soil profile is a very complicated task. We have to know the distribution of organic matter, mineral particle, and microbes, the existence of different barriers, redox conditions etc (Box 3)... 

From 10 to 104 mg kg-1 TCE sorb to low-organic-matter minerals (Estes et al., 1988 Farrell Reinhard, 1994a,b), so all contaminated aquifer materials are potential long-term sinks and longer-term sources of TCE, but little or nothing is known about the mechanisms of adsorption. Clay minerals often comprise the bulk of the surface area in low-organic-matter aquifer materials, so the interactions of TCE and clays are of special interest.
