Assessment and characterization of environmental factors (hazards) and exposures

Investigator: Thomas McKone

Hazard and exposure information relevant to EPHT includes source/emissions data, environmental monitoring data, biological monitoring data, and time-activity-location data for target populations when available and relevant data. In spite of the clear need for EPHT to make use of data about environmental factors to characterize populations with respect to hazards, there is limited capacity for such activities within communities, state agencies and federal agencies. To improve methods to assess and characterize environmental hazards and exposures, we will merge biomonitoring data with geographically-based emissions and environmental sample data to increase the relevance of hazard indicators; and develop new approaches to combine the geographic distributions of environmental factors with information on human population distributions and activities. This is important because biomonitoring data alone do not always capture exposures to environmental hazards.
