New and Updated Chemicals Available

CDC’s National Report on Human Exposure to Environmental Chemicals (referred to as the Report) includes summary data for chemicals that have results available from NHANES starting with the 1999–2000 cycle. The Report is cumulative and includes all data tables previously published. This version of the Report:

• Adds four data tables for two chemicals reported for the first time
• Updates 94 data tables for 45 chemicals measured in urine specimens
