HUMAN EXPOSURE DATABASE SUPPORT AND MANAGEMENT
Impact/Purpose:
o Develop publically accessible databases
o Disseminate human exposure data bases and data tools in an appropriate manner to improve human exposure research and information.
o Ensure that human exposure data sets generated by HEASD and its contractors or collaborators are useful for data analysis and for human exposure modeling, by providing formats and guidance on data base creation, documentation, storage, and retrieval.
o Ensure that data sets produced in HEASD conform with ORD and EPA requirements.
o Compile and translate existing human exposure data sets into useful formats for use by HEASD scientists and modelers.
o Make fully documented human exposure data sets available for researchers with collaborating external organizations.
Description:
Researchers in the National Exposure Research Laboratory (NERL) have performed a number of large human exposure measurement studies during the past decade. It is the goal of the NERL to make the data available to other researchers for analysis in order to further the scientific understanding of human exposure. This task consists of two focus areas. The first is the creating, documenting, and dissemination of human exposure data bases collected by Human Exposure and Atmospheric Sciences Division (HEASD) or its contractors and/or collaborators via the world wide web. Dissemination of these data will provide needed information on human exposure to researchers, assessors, and the public. The work will ensure that data sets on human exposure measurements and on activity patterns and/or exposure factors are available, easily understood, and readily accessible for human exposure analysts and modelers.
The second area of work in this task is to assist the Human Exposure Measurements and the Human Exposure Modeling Teams within HEASD by providing systems-level coordination and guidance on collecting, creating and documenting human exposure data collected by HEASD or its contractors and/or collaborators. The work will ensure that data sets on human exposure measurements, activity patterns, and/or exposure factors are available, easily understood, and readily accessible for the principal investigators and other human exposure analysts and modelers. There will be two focus areas in this task: (1) Provide support to the scientists on the database creation for individual studies, and (2) Build data warehouses to combine related studies together for data modeling and mining. A data warehouse is a database which contains data from different studies. The data is transformed to obtain consistent coding, naming, and formatting of the data elements.
