The Fourth National Report on Human Exposure to Environmental Chemicals, 2009, (the Fourth Report, 2009) presents data for 212 chemicals. The Fourth Report includes the findings from nationally representative samples for 1999-2004.

The blood and urine samples reported in both publications were collected from participants in CDC's National Health and Nutrition Examination Survey (NHANES), which obtains and releases health-related data from a nationally representative sample in two year cycles.
