Kent Thomas

Title: Research Physical Scientist

EPA Division: Human Exposure and Atmospheric Sciences Division

EPA Branch: Exposure Measurements and Analysis Branch

Kent has experience in the development and implementation of strategies and methods for assessing human exposure to environmental contaminants. His experience includes complex multi-media and multi-pathway studies of human exposure to VOCs, pesticides, PCBs, PAHs, metals, and particles. Kent has contributed to the development of sampling and analytical methodology for contaminants in air, water, food, dust, soil, blood, breath, and urine. Additional experience includes studies of pollutants in building and residential environments. His research interests include improving exposure assessment in epidemiological investigations. Kent is currently engaged in cumulative risk assessment research in the Chemical Safety for Sustainability program and in improving exposure and community assessments for children in the Sustainable and Healthy Communities program.
