Health risk assessment is a process that quantitatively evaluates the potential adverse health effects of exposure to specific hazards in the environment. This can include assessing risks associated with exposure to chemical contaminants, radiation, biological agents, physical hazards, and other factors that may impact human health. Health risk assessments typically involve gathering data on the type, concentration, and duration of exposure to a hazard, as well as factors such as age, gender, genetics, and lifestyle that may influence an individual's susceptibility to adverse health effects. The collected data is then used to estimate the likelihood and severity of potential health impacts, such as cancer, respiratory problems, neurological disorders, or other diseases. The results of health risk assessments are used to inform decision-making in areas such as environmental regulation, public health policy, occupational safety, and land use planning. By identifying and quantifying potential health risks, these assessments help to protect individuals and communities from harmful exposures and guide efforts to minimize or mitigate health hazards.
