Exposure risk refers to the likelihood or probability that an individual or population will come into contact with a harmful substance or situation that could potentially cause harm to their health. This research area focuses on identifying, assessing, and managing risks associated with exposure to hazardous materials, pollutants, pathogens, or other harmful agents in various environments such as workplaces, homes, and communities. Researchers in this field often study factors that influence exposure risk, such as environmental conditions, human behavior, and the effectiveness of control measures. The ultimate goal of exposure risk research is to protect individuals and communities from harmful exposures and minimize the adverse health effects that may result from them.
