Environmental Chemicals Data


The National Report on Human Exposure to Environmental Chemicals – U.S. Centers for Disease Control and Prevention (CDC)
Provides an assessment of the exposure of the U.S. population to environmental chemicals through measurement of chemicals or their metabolites in blood and urine samples from a random sample of participants from the National Health and Nutrition Examination Survey (NHANES). This third report presents exposure data for 148 environmental chemicals. It is expected that additional reports will be released every two years.

Data source: National Health and Nutrition Examination Survey (NHANES)
Dates: 1999 -2002
Geographical area: United States
Comments: Tables present the geometric mean and selected percentiles of blood or urine concentrations of each chemical. Data are provided for age, gender, and some race/ethnicity groups. Levels from this report can be used as reference ranges by physicians and scientists to determine whether a person or group has a high exposure. People are selected for NHANES from the civilian, non-institutionalized U.S. population. The data cannot be abstracted to determine levels representative of a particular state. For each chemical some general information is also provided, such as sources of human exposure and known health effects.
