THE ROLE OF EXPOSURE ANALYSIS IN HUMAN HEALTH RISK ASSESSMENT
OZKAYNAK, H. A. THE ROLE OF EXPOSURE ANALYSIS IN HUMAN HEALTH RISK ASSESSMENT. Presented at Exposure Assessment Seminar, Raleigh, NC, April 03, 2006.
The two main objectives of this research are (1) to improve and update and (2) to analyze the CHAD database.
For objective 1, we will
* Reconfigure the CHAD program into a completely modularized Oracle database.
* Redesign User Interface for effcient utilization of the program's capability.
* Obtain dates for those surveys that did not provide them to us, so that we can obtain associated meteorological/climatic inputs for the person-days of information without them.
* Revise the upper and lower bound delimiters in the energy expenditure distributions used for activity-specific estimates.
For objective 2, we will
* Evaluate data quality.
* Evaluate trends and activities for various subgroups.
* Identify temporal patterns for longitudinal data.
* Characterize resolution required for output for exposure and dose models.
This presentation will cover the basic methodologies used for assessing human exposures to environmental pollutants, and some of the scientific challenges involved in conducting exposure and risk assessments in support of regulatory evaluations.
