The National Report on Human Exposure to Environmental Chemicals (NRHEEC) is a series of ongoing assessments of the U.S. population's exposure to environmental chemicals by measuring chemicals in a person's blood or urine. The Environmental Health Laboratory within the Centers for Disease Control and Prevention, National Center for Environmental Health (CDC, NCEH) has produced four of these reports since 2001. The Fourth Report includes findings from national samples for 1999-2000, 2001-02, and 2003-04. Updated tables to the report are produced biennially. The 2019 edition provides data through 2015-16.
