Abstract
The principal components of exposure are the magnitude of the pollutant concentration, the duration of the exposure, and the frequency of the exposure (Sexton and Ryan, 1988). Human exposure assessments of these three components include measuring pollutant concentrations (outdoor, indoor, microenvironmental, personal), but also characterizing personal exposure scenarios, such as activity patterns and ventilation rates. Ecological exposure is the expression of the magnitude, duration, and frequency of contact between an ecological resource and a “stressor;” i.e., a physical, chemical, or biological entity that can induce an adverse response” (Risk Assessment Forum, 1992).
