Research Summary:

Dr. Kevin L. Armbrust is the State Chemist for the State of Mississippi, The Director and Chief of the State Chemical Laboratory of Mississippi and an Associate Professor in the Chemistry department at Mississippi State University. He received both his B.S. degree in Environmental Toxicology and his Ph.D. in Agricultural and Environmental Chemistry from the University of California at Davis in 1987 and 1992, respectively. From 1992 to 1998 he was employed by DuPont Agricultural Products where he was responsible for the design, conduct and generation of laboratory and field experiments according to Good Laboratory Practice (GLP) to determine the persistence and fate of pesticides in soil, water, plants and animals in support of their registration and reregistration. These have included aquatic monitoring and runoff, field dissipation, hydrolysis, aqueous and soil photolysis, batch adsorption/desorption, aerobic soil metabolism, water-sediment degradation, and fish bioaccumulation studies. He was an assistant professor in the department of Crop and Soil Sciences at the University of Georgia from 1998 to 2002, prior to his current position in Mississippi. His current research interests include development of modern analytical methods (e.g. GC/MS/MS and HPLC/MS/MS) to measure agricultural and industrial chemicals in environmental matrices, investigations of the transport of pesticides and pharmaceutical products in soil and water, the influence of sunlight on their degradation in soil and water, environmental and biological processes influencing the degradation of organic chemicals, and the environmental impact of pesticides and industrial chemicals.
