Estimating human exposures to environmental pollutants: availability and utility of existing databases

Abstract

Information about human exposures to environmental agents is a crucial component of informed decisions about protection of public health. Results from an inventory of exposure-related databases are used to examine the value of exposure information for risk assessment, risk management, surveillance of status and trends, and epidemiologic studies. Findings indicate that current and future exposure-related databases should include (1) standardized procedures for the collection, storage, analysis, and reporting of data; (2) an enhanced ability to compare data over time, i.e., conduct comparison studies of "old" and "new" methods; (3) mechanisms for coordination and cooperation among public and private-sector organizations with respect to the design, maintenance, exchange, and review of information systems; (4) measurements of actual exposures and dose for relevant human populations; and (5) data collection, storage, and retrieval methods that permit easy manipulation of information for both model building and testing.
