Description:
The Fourth National Report on Human Exposure to Environmental Chemicals, 2009 (the Report) provides an ongoing assessment of the exposure of the U.S. population to environmental chemicals by the use of biomonitoring. The Report is cumulative (containing all the results from previous Reports) and provides new data for years 2003- 2004. Data for 75 new environmental chemicals are included for the survey period 2003-2004. The Report website http://www.cdc.gov/exposurereport is also the best source for the most recent update of available data.
In each survey period, most chemicals or their metabolites were measured in blood, serum, and urine samples from random subsamples of about 2500 participants from the National Health and Nutrition Examination Survey (NHANES) conducted by the Centers for Disease Control and Prevention’s (CDC’s) National Center for Health Statistics. NHANES is a series of surveys designed to collect data related to the health and nutritional status of the U.S. population. The blood, serum, and urine exposure
measurements presented in the Report were made by CDC’s Environmental Health Laboratory (Division of Laboratory Sciences, National Center for Environmental Health) using mass spectrometry methods. The Fourth National Report on Human Exposure to Environmental Chemicals, Updated Tables,
August 2014 provides nationally representative biomonitoring data that has become available
since the publication of the Fourth National Report on Human Exposure to Environmental
Chemicals, 2009. Over time, some of the chemicals and the samples in which they have been measured have changed. In this release of the Updated Tables, a number of chemicals were measured in a
Special Sample of the U.S. population, namely, adult cigarette smokers and nonsmokers. These
data tables are presented together (Adult Cigarette Smokers and Nonsmokers: Analysis of
Select Chemicals in a Special Sample). A link to a Biomonitoring Summary, information about a
specific chemical or chemical group, is provided at the bottom of many of the data tables. The Fourth National Report on Human Exposure to Environmental Chemicals from 2009 and 2014 are included here.
