Edward O. Edney

Title: Senior Research Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Process Modeling Research Branch

Narrative:
Between 1988 and 2007 Dr. Edney played the lead role in atmospheric chemistry in NERL designing and conducting in-house atmospheric chemistry laboratory, modeling, and field studies, the results of which were used to develop and evaluate EPA air quality regulations. The many investigations conducted included (1) measuring kinetic rate constants and product yields of a wide range of atmospherically relevant gas phase compounds; (2) conducting homogeneous and heterogeneous laboratory studies to assess the fate of CFC substitutes; (3) measuring the bacterial mutagenicity of atmospherically relevant smog chamber mixtures; (4) designing and carrying out laboratory experiments and field studies to assess whether acidic deposition significantly damages materials of constructions including metals and organic coatings as well as structures of artistic and/or historical significance; and (5) designing and conducting laboratory and field studies, the results of which he used to develop for CMAQ, a secondary organic aerosol chemistry model containing improved treatments of aromatic hydrocarbons as well as mechanisms for isoprene and sesquiterpenes. Since 2008 his research has focused on assessing whether computational chemistry could serve as a timely and cost-effective tool for improving EPA air quality models including CMAQ.
