The concept is to establish one well-characterized site, designated as the Chattanooga Metropolitan Statistical Area, at which to conduct a series of studies designed to improve environmental monitoring methods and methods for assessing human exposure to toxic substances in the environment. The project, planned to span a 5- to 15-year period, is being conducted in support of the Toxic Substances Control Act of 1976. The Chattanooga area is well suited as a site to conduct human exposure methodology studies. Site users have the support of local government and of EMTS Project participants who provide a management team, information gathering services, computerized data management and analysis, and quality assurance assistance. The Chattanooga area provides a hospitable climate, a population and geographical size allowing statistically valid sampling of subpopulations, isolation from other cities, a diverse industrial base, a large existing data base, and modern technical and logistical support facilities. 收起
