Monitoring Exposure

While some exposure assessments collect surrogate data such as job titles, work history, questionnaire data, other studies use more direct methods such as measurement data through monitoring of the exposure. Measurement data is commonly collected in the form of a concentration of the agent of interest. Such methods are generally seen as more objective and can consist of area or personal monitoring. Given the amount of resources required to carry out personal monitoring, this can often be a less feasible choice for collecting exposure data.

The remainder of this module will introduce some of the basic concepts for air, biological, dermal, dietary, and noise monitoring includes examples of monitoring methods, equipment, and limitations and considerations.
