Smith, Garon - University of Montana - Department of Chemistry and Biochemistry

个人简介

Garon Smith came to UM in 1991 from State University of New York College at Fredonia. He received his Ph.D. degree in 1983 from the Colorado School of Mines and taught at Colorado College before moving to Fredonia. Garon Smith is an analytical/environmental chemist with broad interests in air and water characterization. He teaches freshman chemistry and undergraduate and graduate courses in analytical and environmental chemistry.

研究领域

The application of analytical/physical chemistry to air and water quality issues is the focus of my group's research activities. Out approach is to: (1) identify the source and extent of contamination; (2) determine how specific contaminants are transported through an ecosytem or airshed; and (3) ascertain their ultimate environmental fate. Field samples are analyzed through a variety of spectroscopic and chromatographic techniques. Finally, we use artificial neural networks to help us match contaminant samples with potential sources. Currently funded research includes: 1) Mathematical modeling of aqueous equilbiria using 3-D trend surpfaces (topos). Software that implements the calculations are embedded as Visual Basic macros in Excel spreadsheets so that no new software need be purchased to use them. 2) Honey bees as biomonitors for compounds used or produced by the military. We have developed highly instrumented bee hives to monitor bee activity and collect for analysis samples of hive air, honey, bees wax and whole bees (see web site). 3) Identification and reduction of air contaminants in urban mountain valleys. We are using thermal desorption/gas chromatography/mass spectrometry to identify various forms of air contaminants. One objective is to identify and reduce organosulfur compounds responsible for odors from kraft pulp mills. 4) 3-D fluorescence of polycyclic aromatic hydrocarbon mixtures. We have developed spectroscopic techniques for tracking underground movement of diesel plumes and remediation of creosote-contaminated soils. Because I am active on quasi-legislative/quasi-judicial environmental boards, my students often work at the science/policy interface. We routinely interact with environmental directors from industry and regulatory officials at the local, state and federal level.
