Abstract
A universal method is presented for the use of pyrolysis-soft ionization mass spectroscopy and related analytical pyrolysis methods in a comprehensive characterization of complex biological and technical materials. As an example, the integrated pyrolysis-field ionization mass spectra of organic matter which occurs in different environmental compartments of the geoecological and geochemical system are presented and discussed. Furthermore, pyrolysis-field ionization mass spectroscopy is applied to the problem of current forest damage. Mass spectral fingerprints are produced for healthy and damaged spruce needles and chemometrically evaluated by pattern recognition techniques. In an integrated approach the major results are summarized and discussed together with spectroscopic, chemical, biological and geochemical data. Based on the presented overview, future fields of analytical pyrolysis studies are suggested comprising the rapid screening of contaminants in environmental samples, the early detection of chemical changes in biological materials exposed to environmental stress and the establishment of property-structure relationships.
