Multiple Pathway Exposure Factors (PEFs) associated with multimedia pollutants
This paper describes methods for addressing several potential exposure pathways and provides a link between human exposure and chemical concentrations in multiple environmental media. This approach links environmental concentrations to human exposure through pathway-exposure factors (PEFs). The PEF incorporates information on human physiology, human behavior patterns, and environmental transport into a term that translates a unit concentration (in mg/m/sup 3/, mg/kg, or mg/L) in a specified environmental media (air, soil, or water) into daily exposure in mg/kg-d for a specified route (inhalation, ingestion, or dermal absorption). This process of exploring the data associated with human/environment interactions and proposing exposure models provides insight for risk-management activities. 11 refs., 1 fig., 3 tabs.
