Dioxins/Furans - High Resolution Mass Spectrometry

Ultra trace level dioxin/furan analysis is available by EPA 1613, SW-846 8290, Method TO-9 for ambient air and Methods 0023A and 23 for source emissions testing.  Current EPA methods are for 17 of the 210 congeners.  These congeners are:    

Dioxin Congeners CAS Number Furan Congeners CAS Number
2,3,7,8-TCDD 1746-01-6 2,3,7,8-TCDF 51207-31-9
1,2,3,7,8-PeCDD 40321-76-4 1,2,3,7,8-PeCDF 57117-41-6
1,2,3,4,7,8-HxCDD 39227-28-6 2,3,4,7,8-PeCDF 57117-31-4
1,2,3,6,7,8-HxCDD 57653-85-7 1,2,3,4,7,8-HxCDF 70648-26-9
1,2,3,7,8,9-HxCDD 19408-74-3 1,2,3,6,7,8-HxCDF 57117-44-9

OCDD 3268-87-9 2,3,4,6,7,8-HxCDF 60851-34-5
    1,2,3,4,6,7,8-HpCDF 67562-39-4
    1,2,3,4,7,8,9-HpCDF 55673-89-7
    OCDF 39001-02-0

Many programs require the Toxic Equivalence Factor (TEF) methodology using consensus TEF values for 2,3,7,8 TCDD published by the World Health Organization (WHO). Eurofins TestAmerica can work with our clients to provide these calculations in our final data report.

Eurofins TestAmerica laboratories can also report the dioxin/furan concentrations by their homologue groups for the clients to calculate a Total dioxin/furan concentration. This calculation would include the following homologues:

Dioxin Homologues


Furan Homologues

Polychlorinated Dibenzo-p-dioxins PCDDs Polychlorinated Dibenzofurans PCDFs
Monochlorodibenzo-p-dioxins MCDD Monochlorodibenzofurans MCDF
Dichlorodibenzo-p-dioxins DCDD Dichlorodibenzofurans DCDF
Trichlorodibenzo-p-dioxins TrCDD Trichlorodibenzofurans TrCDF
Tetrachlorodibenzo-p-dioxins TCDD Tetrachlorodibenzofurans TCDF
Pentachlorodibenzo-p-dioxins PnCDD Pentachlorodibenzofurans PnCDF
Hexachlorodibenzo-p-dioxins HxCDD Hexachlorodibenzofurans HxCDF
Heptachlorodibenzo-p-dioxins HpCDD Heptachlorodibenzofurans HpCDF
Octachlorodibenzo-p-dioxin OCDD Octachlorodibenzofuran OCDF

There are methods  which are appropriate for specific matrices and programs including drinking water, TMDL programs, source emissions testing, ambient air monitoring, sediment and tissue projects. A summary of method choices by matrix includes:  

Analytical Method Selection by Matrix

Matrix Method
Water EPA Method 1613; SW-846 Method 8290
Solid (soil, sediment, sludge, tissue, dust, and other matrices) EPA Method 1613; SW-846 Method 8290

Source Air EPA Methods 0023A and 23

Dioxins and Furans are Persistent Organic Pollutants

Dioxins and furans are persistent organic compounds that are by-products of natural process such as forest fires and volcanic activity. They are also the unwanted by-product of some industrial processes such as metal smelting, chlorine bleaching and the manufacturing of pesticides and herbicides.  Chemically, dioxins and furans are stable and are formed when select organic compounds and chlorine are heated to very high temperatures.   The most studied dioxin congener is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), pictured below.

When released into the air, some dioxin/furans are transported long distances and, as a result, are found in most parts of the world. When dioxins are released into water, they can reach sediments where they can be further transported or ingested by fish and other aquatic organisms.  Dioxins degrade very slowly and may bioaccumulate up the food chain.
