New Visual Guide Available for National Exposure Report
CDC created a visual guide that illustrates which biomarker groups are reported in its National Report on Human Exposure to Environmental Chemicals (Report). The visual guide can assist scientists, public health officials, physicians, and others on available exposure information in the Report.
A link to the visual guide, titled "Biomarker Groups in the National Exposure Report," can be found in the "Chemical Information" box on the National Report on Human Exposure to Environmental Chemicals webpage.
The Report provides information using individual and pooled blood or urine samples tested by 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). Not all chemicals or their metabolites were measured in each NHANES cycle. See Chemical Selection for more information on how chemicals are selected for measurement.
