Abstract. Arsenic is a natural part of the environment and may enter the food supply via contaminated soil or groundwater. This publication presents a research project to determine the concentration of arsenic in food via graphite furnace atomic absorption spectroscopy. This project is a real world example that connects students to their coursework and is applicable to students with little or no analytical experience outside of general chemistry.
