Light oils are notoriously difficult to match to their sources after environmental weathering. A new accelerated laboratory-weathering procedure, combined with either log-ratio or vector pattern recognition, gives markedly improved identification of spilled light fuel oils by infrared spectroscopy.

Their interests, as far as I have identified them, are for learning the applied chemistry of (1) processes for identification of matter by physical and chemical properties, (2) practices of chemistry concerned with water, soils, foods, the

It all began on a hot, humid day in August of last year. I. M. Greede was surveying the property that surrounded his lakeside cottage. His cottage was not unlike his neighbors', even though he was a multi-millionaire and did not have to make second mortgage payments..(Anderson, Carol. The Mystery of the Chemical Household; 1986).
