Abstract:
Recent trends in the development of environmental analysis are reviewed with emphasis on the progress in extraction techniques, methods of analysis of pesticide residues in food, advances in the search for chemical and biological agents released into the environment (pollution and terrorism), and of related analytical instrumentation. A variety of new sorbents have been synthesized for the extraction and the concentration of many pollutants. These include general purpose adsorbents (e.g., porous polystyrene/divinylbenzene resins) and polymers imprinted for the capture of specific compounds. New, faster, more selective and more sensitive methods have been recently developed to improve analytical performance. Among those covered are synthetic fibers used to grab samples of organic pollutants in air and stir-bars coated with polymethylsiloxane that allow fast and accurate analyses of food contaminants (e.g., pesticide residues). Bidimensional gas chromatography has brought a considerable leap in separation power and sensitivity. Finally, the combination of open tubular columns and of a miniaturized quadrupole mass spectrometer allows the rapid identification of viral agents or a wide variety of chemicals. Results of certain efforts invested in the development of rapid and sensitive methods of detection for a variety of harmful substances that could be spread by terrorists will be indicated.

Georges A. Guiochon graduated with a MS degree in engineering at Ecole Polytechnique (Paris, France) and received a Ph.D. in chemistry from the University of Paris. He was a Professor of chemistry at Ecole Polytechnique (until 1985) and at the University of Paris VI or Universite Pierre et Marie Curie (until 1984), then at Georgetown University (1984-87). He was appointed a UTK/ORNL Distinguished Scientist in June 1987 and is now a Distinguished Professor at the University of Tennessee (Department of Chemistry) and a Senior Scientist at the Oak Ridge National Laboratory (Division of Chemical and Analytical Sciences).
Dr. Guiochon's research interests include all aspects of gas and liquid chromatography, theory, instrumentation and applications, and the problems of physical chemistry related to chromatography. These include solution and adsorption thermodynamics, mass and energy transfers, detector principles, and the consolidation of beds of fine particles. His current work is in the theory of nonlinear chromatography, the development of separation processes based on chromatography (including SMB), and the preparation of efficient columns. He has nearly 800 scientific publications. His most recent books are "Quantitative Gas Chromatography,” written in cooperation with C. Guillemin and published by Elsevier (1988) and "Fundamentals of Preparative and Nonlinear Chromatography,” written in cooperation with S. G. Shirazi and A. M. Katti and published by Academic Press (1994).
Dr. Guiochon organized four major International Symposia on Chromatography (ISC in 1974 and 1980, HPLC in 1981 and 1988) and sixteen Symposia on Preparative Liquid Chromatography (between 1985 and 2003). He is a member of the editorial boards of Chromatographia, the Journal of Chromatography, the Journal of Liquid Chromatography and the Journal of Chromatographic Sciences. He was the first foreign member of the Editorial Advisory Board of Analytical Chemistry and the Associate Editor of this journal for the Separation Sciences in 1985-1993.
Dr. Guiochon is an Honorary Member of the Chromatographic Society of the UK, of GAMS (the French Society of analytical chemistry), and of the Spanish Royal Society of Physics and Chemistry. He was awarded the 1978 Silver Medal of C.N.R.S. (the French NSF); the 1978 Dal Nogare Award of the Chromatography Forum of the Delaware Valley; the Tswett Medal of Advances in Chromatography; the Tsvet Medal of the Russian Academy of Sciences; the A.J.P. Martin Award of the Chromatographic Society in 1980; Honorary Doctorates by the Technical University of Budapest (Hungary) in 1991, by the University of Pardubice (Czech Republic) in 1999, and by the University Ramon Llull in Barcelona, Spain in 2002; the 1991 Separation Sciences Award and the 1998 Chromatography Award of the American Chemical Society; the Eastern Analytical Symposium Award in Separation Sciences in 2001; the Placo de Honor of the Spanish Research Council in 2002; the Research Award of CASSS in 2002. In 1994, he received an Alexander von Humboldt Award as a Senior American Scientist. He spent nine months in 1994-1995 working in the Institut für Organische Chemie of the University of Tübingen.
