Risk Assessment is a process for determining the likelihood of disease, injury, or death to plants, animals, humans, and the environment. The scientific principles learned through the study of toxicology and environmental science are integral to understanding the probability or risk of harmful events. The outcome of these assessments is offered as advice to environmental regulators and the general public. The studies offered by Department of Environmental and Occupational Health Sciences are integral to improving the scientific evidence of harmful events as well as the practical implications for the health and welfare of people and their environment.
