Fourth National Report on Human Exposure to Environmental Chemicals: Updated Tables, January 2019, Volume One [open pdf - 21MB]
"The 'Fourth Report on Human Exposure to Environmental Chemicals, Updated Tables, January 2019' (the 'Updated Tables, January 2019') presents nationally representative, cumulative biomonitoring data gathered from 1999-2000 through 2015-2016. It includes all the data from each of the previous 'National Reports on Human Exposure to Environmental Chemicals' and each of the previous 'Updated Tables' (collectively, the 'Report' and 'Updated Tables'). In each survey period, the reported chemicals or their metabolites were measured in blood, serum, and urine samples from random subsamples of the National Health and Nutrition Survey (NHANES). These subsamples typically consisted of about 2,500 participants - exact numbers are included in the tables. Survey data and samples are collected by the Centers for Disease Control and Prevention (CDC's) National Center for Health Statistics. CDC's Environmental Health Laboratory (Division of Laboratory Sciences (DLS), National Center for Environmental Health) used mass spectrometry methods to obtain the blood, serum, and urine exposure measurements presented in the 'Report' and 'Updated Tables'."
