GARRISON, A. W. Stereochemistry Considerations Can Improve Pesticide Safety and Sustainability. Presented at The Southeastern Regional Meeting of the American Chemical Society, Raleigh, NC, November 14 - 17, 2012.
Impact/Purpose:
Presentation at the Southeastern Regional Meeting of the American Chemical Society, for the Symposium on Chiral Agrochemicals
Description:
About 30% of pesticides are chiral molecules and therefore exist as two or more stereoisomers, which can differ significantly in their toxicity, biodegradation, and persistence. Such differences determine their relative safety to humans and environmental species. Enantiomers, mirror image optical isomers, are the best known examples of stereoisomers that can show these differences. Use of the appropriate single or enriched enantiomer (or enantiomer) can be practical and effective pesticide safety measure and contribute to the sustainability of pesticide use. This presentation will present evidence from the scientific literature and the author’s work for stereoselective biodegration, presistence and toxicity and give examples of currently used single- and enriched-enantiomer pesticides.
