CDC's goal is to make biomonitoring exposure information for the U.S. population available as soon as possible to the public and scientific community. To meet this goal, CDC periodically releases the National Report on Human Exposure to Environmental Chemicals (the Report) and also publishes biomonitoring exposure information in peer-reviewed publications. The Report is cumulative, providing biomonitoring exposure data starting in 1999 through the latest available data at the time of the Report release. Peer-reviewed publications that are published since the latest release of the Report provide more recent and supplementary biomonitoring data for the U.S. population. The Report Web site is a one-stop source that contains both the most recent version of the Report as well as these later biomonitoring publications. Peer-reviewed publications typically also contain more extensive data analysis than that provided in the Report.
Most of the new data to be released in the Fourth Report comes from the NHANES 2003-2004 survey period. The list of the chemicals that CDC is measuring in selected participants for NHANES 2003-2004 is provided in Table 1.
