National Report on Human Exposure to Environmental Chemicals
The National Report on Human Exposure to Environmental Chemicals is a series of ongoing assessments of the U.S. population’s exposure to environmental chemicals using biomonitoring. The Report presents nationally representative and cumulative biomonitoring data gathered from 1999-2000 through 2017-2018.
The Report provides information using individual and pooled blood or urine samples tested by Centers for Disease Control and Prevention (CDC) scientists in the Division of Laboratory Sciences. The samples are from people who took part in CDC’s National Health and Nutrition Examination Survey (NHANES). Because of NHANES’ study design, the measurements of chemicals in participants are representative of exposures in the U.S. civilian population.
The Report does not provide health or toxicity information, state- or community-specific data, specific product or environmentally related information, regulatory guidelines or recommendations.
