# Fourth National Report on Human Exposure to Environmental Chemicals,

Updated Tables, March 2013

The Fourth National Report on Human Exposure to Environmental Chemicals, Updated Tables,

March 2013 provides nationally representative biom onitoring data that has become available

since the publication of the Fourth National Report on Human Exposure to Environmental

Chemicals, 2009 . The Updated Tables, March 2013 includes all the updates previously

provided in Updated Tables, July 2010; Updated Tables, February 2011; Updated Tables,

February 2012 and Updated Tables, September 2012 . Since publication of the Fourth Report,

2009 , 117 chemicals have updated tables and 34 chemicals have been added, for a total of 151

chemicals presented in these Updated Tables

.

A link to information about specific chemicals or the chemical group is provided at the bottom of

the data table page, and it is referred to as a Biomonitoring Summary. For many chemicals,

there is also a link provided to a brief overview about the chemical, referred to as a Fact Sheet.

Two appendices are updated to include information pertinent to these chemicals, as well as the

other chemicals included in the Updated Tables (Appendix C. References for Biomonitoring

Methods; Appendix D. Limit of Detection Table).

The chemicals included in this update are listed in the table that follows.

The Report website is the best resource for the most recent updates of available data

( http://www.cdc.gov/exposurereport ). The Report website also contains details of the Data

Sources and Data Analysis, Interpretation of Report Data, and Chemical and Toxicological

Information that pertain to the Updated Tables.

# What’s New and Different?

The Updated Tables

in this release include several chemicals that have results available from

one or more of the three survey periods of 2005-2006, 2007

- 2008 , and 2009- 2010

. The

chemicals with updated data in this release are two fungicide metabolites, ethylene thiourea and

propylene thiourea; four organophosphorus insecticides or metabolites; the anions, thiocyanate

and nitrate; phthalate metabolites; phytoestrogens and metabolites; and polycyclic aromatic

hydrocarbon metaboli te s

.

The limits of detection (LOD) for phytoestrogens were stated incorrectly in NHANES 2003- 2004

, and they have been corrected in this release of the Updated Tables. These differences did not

alter the geometric means or percentiles for the phytoestrogens as shown in the Fourth Report

on Human Exposure to Environmental Chemicals and in the Updated Tables

.

The polycyclic aromatic hydrocarbon metabolite, 4-hydroxyphenanthrene, has results available

only for NHANES 2003-2004 and 2005-2006. This chemical is no longer measured after

NHANES 2005-2006 because there were potential interferences in the method that would affect

the quality of the results.

** In the 2001 -2002 survey period, 83% of measur ements had an LOD of 0.015 ng/mL, and 17% had an LOD of 0.05 ng/mL.

< LOD means less than the limit of detection, which may vary for some chemicals by year and by individual sample.

* Not calculated: proportion of results below limit of detection was too high to provide a valid result.

***Non -smoking is defined as a serum cotinine concentration of 10 ng/mL or less.

### Appendix D. Limit of Detection Table

The analytical limit of detection (LOD) for each of the different chemical measurements is presented in the table below. The LOD is the

level at which the measurement has a 95% probability of being greater than zero (Taylor, 1987). As analytical methods improve, LODs

will often change. For this reason, LOD results are reported by survey periods (e.g., 1999-2000, 2001-2002, 2003-2004, 2005-2006,

2007-2008, 2009-2010).
