2 August 2010
The CDC released the Fourth National Report on Human Exposure to Environmental Chemicals, a comprehensive assessment of the exposure of the U.S. population to 212 chemicals, 75 of which have never been measured previously in the blood and urine of the U.S. population. The blood and urine samples were collected from participants in the CDC's National Health and Nutrition Examination Survey, which samples the U.S. population every two years.
