The speaker, Larry Keith, is a pioneer in environmental chemistry, having been involved in the field since the 1960s. He has published numerous works and was instrumental in setting the limits for certain chemicals. The talk will cover his experiences and the historical development of environmental chemistry, focusing on the time before the Environmental Protection Agency (EPA) and early work on analyzing pollutants from paper mills using techniques like GC and NMR. The speaker will also discuss collaborations with other scientists and the formation of the American Chemical Society’s Georgia chapter.
