Book Description
This work provides detailed coverage of the applications of proven spectometric techniques in soil science. It presents analytical approaches important in the study of pool sizes and the dynamics of macro- and micronutrients, the structure and function of soil organic matter, and the co-evolution of soils, plant communities and climate. Interdisciplinary perspectives from soil science, ecology, geology, chemistry, biogeochemistry, agronomy and physics, are offered.

Book Description
When a dose of drug is administered, three main phases of drug action may be distingushed. In the "pharmaceutical" phase the dosage form disintegrates, the active substance dissolves and becomes available for absorption. The second phase ("pharmaco kinetic" phase) includes absorption, distribution, metabolism, and excretion. That fraction of the dose which finally reaches the circulation after absorption will be available for biological action in the third, or "pharmacodynamic" phase when the drug reaches the target tissues and a drug-receptor interaction takes place. The objectives in studies of drug metabolism are: (a) to identify the pathways by which drugs are transformed in the body; (b) to ascertain quantitatively the importance of each pathway and intermediate; (c) to identify and quantify endogenous constituents influenced by the drug or its metabolites which may interfere with common metabolic processes. Since metabolites usually differ from their precursors by only a single chemical group, the resulting metabolic pathways generally consist of a series of closely related compounds. Mass spectrometry is uniquely suited for the analysis of drugs and metabolites for several reasons: only a minimal amount of sample preparation is needed, closely related compounds can be analyzed in a single step, structures can often be deduced directly from the mass spectra without the need for pure reference spectra, and constituents can be quantified with relative ease even when present in fractional nanogram quantity.
