Abstract
In 1998, the U.S. Environmental Protection Agency (U.S. EPA) established the National Dioxin Air Monitoring Network (NDAMN) to help characterize the ubiquitous presence of dioxins in the environment. This final report represents the 2013 update to NDAMN.
Dioxins are toxic chemicals that naturally exist in the environment and can be released into the environment through forest fires, backyard burning of trash, certain industrial activities, and residue from past commercial burning of waste. When released into the air, dioxins may be transported long distances. Because of this, dioxins are found in most places in the world. It is important to understand the air levels of dioxins and dioxin-like compounds in order to better understand dioxin exposure.
The National Dioxin Air Monitoring Network (NDAMN) was developed to determine background air concentrations of certain dioxins and dioxin-like compounds, specifically polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and coplanar polychlorinated biphenyls (cp PCBs). This report describes the atmospheric levels of dioxin-like compounds in rural and agricultural areas where livestock, poultry, and animal feed crops are grown and provides measurements of atmospheric levels in different geographic regions of the U.S.
NDAMN began operating in 1998 with 10 sampling stations; this was expanded to 34 stations by 2003. The stations were categorized as urban (4 stations), rural (23 stations), or remote (7 stations). The last NDAMN sample was taken in November 2004. The full database includes 685 samples, measured for 17 dioxin and furan congeners, 8 dioxin and furan homologue groups, and 12 dioxin-like polychlorinated biphenyl congeners (PBCs).
