This website provides visitors with information and materials regarding research projects in human exposure. The field of human exposure is defined as the study of human contact with toxic chemical, physical or biological agents occurring in a specific environment. Toxic agents may travel through air, water, soil, or food systems before reaching a human being's lungs, skin, or gut. Exposure scientists aim to advance knowledge of the mechanisms and dynamics of events that may cause or prevent adverse health in people.
