The National Health and Nutrition Examination Surveys NHANES) provide a mechanism for describing the prevalence and magnitude of environmental exposures in the U.S. population through measurements of toxicants in biological specimens and other measures. Environmental toxicant measures from past NHANES have provided key data for environmental policy development and exposure research. For example, data on blood lead levels from the second NHANES (1976-1980) were instrumental in eliminating lead from gasoline and solder in food and soft drink cans. Measures of environmental exposures have been greatly expanded in the current survey. Blood and urine specimens that are routinely collected from survey participants offer a rich resource for measurement of toxicants and/or metabolites. These specimens are being utilized to measure lead, cotinine, persistent pesticides, dioxins, furans, PCBs, non- persistent pesticides, poly-aromatic hydrocarbons, phthalates, and heavy metals. In addition, the survey includes the following environmental exposure components: 1) a comprehensive assessment of exposure to volatile organic compounds through use of personal exposure badges and measures in blood and home tap water samples; 2) measure of mercury levels in hair samples, as well as in blood and urine specimens; and 3) an assessment of lead in dust samples obtained from homes with young children.

Learning Objectives: At the conclusion of this presentation, the participant will be able to articulate the environmental exposure measures from NHANES and their use for establishing national priorities, setting standards, and evaluating the effectiveness of environmental regulatory efforts
