Dioxins and Furans

Dioxins and Furans are Persistent Organic Compounds

Dioxins and furans are persistent organic compounds that are by-products of natural and industrial processes.  Chemically, dioxins are stable and are formed when select organic compounds and chlorine are heated to very high temperatures.   The most studied form of dioxin is the 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) isomer, pictured below.

When released into the air, some dioxins are transported long distances and, as a result, are found in most parts of the world. When dioxins are released into water, they tend to settle into sediments where they can be further transported or ingested by fish and other aquatic organisms.  Dioxins degrade very slowly and may bioaccumulate in the food chain such that aquatic species have higher concentrations than plants, water, soil, or sediments.  

How Can Eurofins TestAmerica Help You?

Eurofins TestAmerica has more than 25 years of experience with the analysis of dioxins/furans by both low resolution and high resolution mass spectrometry techniques and we offer a full range of dioxin/furan analyses in water, soil, sediment, tissue and air by EPA methods.  TestAmerica offers one of the largest capacities in the United States, maintaining a continuous investment strategy in state-of-the-art equipment and methodology. Eurofins TestAmerica’s Knoxville, TN and Sacramento, CA laboratories provide nationwide coverage for your dioxin/furan analytical needs.

 Doxins/Furans - High Resolution

Ultra trace level dioxin analysis is available by EPA 1613, SW-846 8290, Method TO-9 for ambient air and Methods 0023A and 23 for source emissions testing.  Typically, 17 isomers are evaluated at the part per trillion to part per quadrillion level, and total homologs and/or toxic equivalency factors can also be reported.   These methods are most appropriate for drinking water programs, TMDL programs, source emissions testing, ambient air monitoring, sediment projects, risk assessments and Superfund site investigations. The methods are applicable to a wide variety of matrices including air, water, sediment and tissue.
