Exposure Setting

Overview

An exposure setting is the physical setting where an exposure of interest occurs. It is defined by the boundaries of the analysis and the scope and geographic scale of the assessment. Relevant environmental information might include data on groundwater flow, soil type, surface water characteristics, meteorological conditions, types of land use, and persistence of the agent or stressor. Data about the exposed population or life stage can also be part of the exposure setting.
