1. Identify and characterize chemical and physical processes occurring in, on, and around plants that influence xenobiotic-degradation for developing appropriate agronomic practices and new approaches for mitigating contamination of soil and water resources within the State of Arkansas and across the mid-South.
2. Monitor the occurrence of chemical contaminants in the environment and assess the impact of agricultural production systems on the fate and transport of chemical contaminants through the components of the biosphere, with a focus on Arkansas and the states of the mid-South.
