National Human Exposure Assessment Survey (NHEXAS) Data Analysis Work Group
The purpose of this project is to represent NCEA on the NERL-led NHEXAS work group and to participate in activities including analysis of data from NHEXAS and development of the NHEXAS data base.
Two relatively large cross-sectional studies (150-300 respondents completing the protocol) were conducted in Arizona and in EPA Region 5. A special study of children's exposure to pesticides was conducted in Minnesota. A special study was also conducted among approximately 60 participants in 4 counties in Maryland, including Baltimore City, where people were revisited 6 times over a 1-year period.
In 2002, the NHEXAS data was publically released on the Internet. In 2001 a workshop was held and in 2002, the work group completed a report on "lessons learned," documenting observations of the the Principle Investigators of the NHEXAS collaborating organizations on project management, study design, sample collection and analysis, data analysis and database development, and communication.
