Methods for Assessing Exposure to Chemical Substances. Volume 4. Methods for Enumerating and Characterizing Populations Exposed to Chemical Substances

摘要

The report, one of a series of reports concerning exposure assessment, describes methods for estimating the sizes of populations potentially exposed to chemical substances. Five categories of exposed populations are covered: (1) populations exposed to chemicals in the ambient environment, (2) workers, (3) populations exposed through ingestion of chemicals in food, (4) users of consumer products, and (5) populations exposed through ingesting chemicals in drinking water. The report contains general data on populations from governmental agencies such as the U.S. Bureau of Census, U.S. Department of Labor, U.S. Department of Agriculture, and EPA's Office of Drinking Water. It also contains step-by-step methods for locating and using data to enumerate each subpopulation identified as potentially exposed to toxic chemicals. Appendix A contains sample calculations illustrating the methods presented in the text. Appendix B is OSHA's Industry-Occupation (I-O) Matrix, described in Section 3 of the report.
