Other affiliations: Dr. Parkinson has served as a book reviewer for Chemistry in Britain (Royal Society of Chemistry) and for ACCN (the Chemical Institute of Canada). In addition he has served as a reviewer for Tetrahedron Letters and the Petroleum Research Fund (USA).

Professional Organizations: Dr. Parkinson has been a long standing member in many societies and divisions, to include:the Chemical Institute of Canada, the Royal Society of Chemistry,the American Chemical Society, the Society for Applied Spectroscopy, the Greater Boston Magnetic Resonance Group and the American Association for the Advancement of Science.

Scholarly Interests:

Dr. Parkinson was educated at Brock University, St. Catharines, Ont. (B.Sc. (Hon. Chemistry) 1976) and at Queen Mary & Sir John Cass School of Science and Technology, University of London (Ph.D. Spectroscopy and Analytical Chemistry, 1987). Dr. Parkinson's PhD thesis involved the preparation, extraction, reactivity and the complete elucidation of some 70 novel and environmentally important organophosphorus compounds involving many analytical techniques including: mass spectroscopy, gas and liquid chromatography, infra-red and 2D multinuclear NMR spectroscopies. He is presently (as of 1995) an assistant professor in the Chemistry Group of the Environmental Science programme at S.W.G.C. Previous to this, 1992-95, Dr. Parkinson was appointed as an Assistant Professorof Spectroscopy and Analytical Chemistry at Bishop's University, Lennoxville, Quebec. From 1987 to 1992 he was a Research Associateand an Instrumentation Specialist in magnetic resonance and mass spectroscopy in the Chemistry department of Tufts University. Here the interest of the work was (1) in the development of amobile GC-MS system and (2) managing a contract service NMR and mass spec. laboratory. Prior to this he held positions at theUniversity of London as Principle NMR Spectroscopist at Royal Holloway and Bedford New College (1985-90), and as the University of London's Low Field Multinuclear NMR Manager at Bedford College (1980-85).

Current Interests:

Currently research efforts include environmental analysis, isomeric separations, biochemical separations, electroanalytical chemistry and multinuclear magnetic resonance spectroscopy. Research interests in environmental chemistry involve the use of gas and liquid chromatographies, GC-mass spectroscopy, atomic absorption spectroscopy and the development of specific chromatographic and absorptive detectors for the identification and quantification of environmentally important compounds, heavy metals and trace VOC's. In particular, investigations in the chemical constituents of oil and its interaction with waterby HPLC, GC, and GC-MS; selective trace heavy metal uptake inaqueous systems (fresh and saline waters) by algal materials for the concentration and subsequent detection by AA spectroscopy; the integration of solid phase membrane extraction methods for isolation and concentration of volatile and semi-volatile organics in aqueous systems for subsequent GC-MS elucidations; and useof multinuclear nD NMR spectroscopy for configuration and topology determinations of environmentally important compounds . Here aluminum,phosphorus, selenium, silicon and tin organo-metallic compounds are of particular interest.
