Health Risk Assessment
Health Risk Assessment (HRA) is a systematic approach used to identify potential health risks associated with exposure to specific hazards. It involves the evaluation of information on the hazardous properties of substances, and the extent and nature of exposure to them.
Overview[edit | edit source]
The primary goal of a Health Risk Assessment is to provide a scientific basis for public health decisions and policies. It is a key component of risk management and risk communication, and is used in various fields such as environmental health, occupational health, public health, and medicine.
Process[edit | edit source]
The process of a Health Risk Assessment typically involves four steps:
- Hazard Identification: This step involves determining whether a particular substance is or is not causally linked to particular health effects.
- Dose-Response Assessment: This step involves characterizing the relation between dose of the substance and occurrence of health effects in humans.
- Exposure Assessment: This step involves measuring or estimating the intensity, frequency, and duration of human exposures to the substance.
- Risk Characterization: This step involves estimating the extent of human health risk associated with exposure to the substance.
Applications[edit | edit source]
Health Risk Assessments are used in a variety of settings, including:
- Environmental Health: In this field, HRAs are used to assess the risk of exposure to environmental hazards such as air and water pollution, hazardous waste, and radiation.
- Occupational Health: In this field, HRAs are used to assess the risk of exposure to hazards in the workplace, such as chemicals, noise, and physical hazards.
- Public Health: In this field, HRAs are used to assess the risk of exposure to hazards in the community, such as infectious diseases, foodborne illnesses, and health effects of climate change.
- Medicine: In this field, HRAs are used to assess the risk of exposure to hazards in medical treatments, such as side effects of drugs and complications of surgeries.
