Multi-element analysis for environmental characterization
Before starting to characterize the environment by its ele— mental composition, it may be useful to ask about the objective of these efforts. This includes questions about the scope of environmental protection, the definition of the environment and the limitations of its characterization by elemental composition alone. In the second part of this lecture, examples are given of the elemental composition of well analysed samples from the atmosphere, hydrosphere, lithosphere and biosphere. The third part introduces the principle of multi— element analysis and the fourth part gives examples. Finally, future aspects of modern chemical analysis are outlined with respect to the multi—element principle.
