What is the purpose of a health risk assessment?

A health risk assessment is a systematic process used to identify and evaluate the potential health risks associated with environmental exposures. This process involves assessing the nature and severity of hazards, estimating the likelihood of exposure to those hazards, and evaluating the potential health effects on affected populations. The strengths of this approach lie in its ability to provide a scientific basis for decision-making and policy formulation aimed at protecting public health.

The core function of a health risk assessment is to understand how certain environmental factors—such as pollutants, chemicals, or pathogens—could impact human health. By identifying the possible adverse effects on various populations, policymakers and health professionals can devise strategies to mitigate these risks and enhance public safety.

While it's important to consider economic impacts of regulations, increase public awareness about pollution, and establish emergency procedures, these elements do not encompass the primary aim of a health risk assessment itself. The focus is specifically on evaluating health-related risks rather than broader socioeconomic or procedural concerns.
