Which question is not typically answered by exposure assessment?

1. Toxicity of the exposure

2. Frequency and duration of exposure

3. Population exposed

4. Route of exposure

The correct answer is: Toxicity of the exposure

Exposure assessment primarily focuses on characterizing and quantifying the exposure of individuals or populations to specific agents or stressors. This involves understanding aspects like frequency and duration of exposure, the population that is exposed, and the route through which exposure occurs. The toxicity of the exposure, on the other hand, pertains to the health effects that a particular agent can have on individuals or populations. This is generally determined through toxicological studies and risk assessments rather than through the exposure assessment itself. Therefore, while understanding the toxicity is crucial for evaluating health risks, it is not a direct question that exposure assessment aims to answer.
