Updated Tables, January 2017

This Updated Tables, January 2017, provides nationally representative biomonitoring data that became available since the publication of the Fourth National Report on Human Exposure to Environmental Chemicals, 2009. This report includes data made available from NHANES survey periods 2005-2006, 2007-2008, 2009-2010, 2011-2012, 2013-2014, and pooled samples using corrected NHANES sampling weights. The Updated Tables are now represented in two separate volumes: Volume One contains data tables for most of the chemicals measured in the U.S. population; Volume Two contains data tables for organic pollutants and pesticides measured in pooled samples and adult cigarette smokers and nonsmokers. For additional details, see the Introduction section of the Updated Tables, Volume One, January 2017.

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.
