Deborah Bennett Fate, transport, and exposure to chemicals in a multimedia environment within the context of environmental exposure and risk assessment. My work currently focuses on organic compounds in the indoor environment, including partitioning to the various surfaces in the home. Research techniques include both modeling approaches and measurement studies. Volatile organic compounds, pesticides, and flame retardants are emphasized.
