While exposure refers to contact between a substance and the surface of the human body via inhalation, ingestion, or dermal contact, biomarkers provide information about the activity of a substance once it is absorbed. Whether the agent of interest is the original substance to which the individual was exposed or a metabolite, biological monitoring can provide useful information about exposure, early health effects, and susceptibility. Figure 22-1 presents a conceptual model for exposure-related disease.
