Where do dioxins and furans come from?
Dioxins and furans are the common names for a group of chemicals that are formed during combustion processes such as waste incineration, power generation, metal production, and fuel burning. These compounds are found in small amounts in the air, water and soil.
What does dioxin mean?
Dioxins are a group of chemically-related compounds that are persistent environmental pollutants (POPs). Dioxins are found throughout the world in the environment and they accumulate in the food chain, mainly in the fatty tissue of animals.
Is TCDD a Pcdd?
The most toxic and most extensively studied representative of the chlorinated dioxins (PCDDs) is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Its structural formula is shown in Fig.

Do dioxins break down?
Dioxins can travel long distances in the air or water. When they settle in soil and sediment, they can stay there for a long time because they break down slowly.
What do furans do to the body?
How Dioxins, Furans, and Dioxin-Like PCBs Affect People’s Health. Human health effects from low environmental exposures are unclear. People who have been unintentionally exposed to large amounts of these chemicals have developed a skin condition called chloracne, liver problems, and elevated blood lipids (fats).
What is the difference between dioxins and furans?
All dioxins have the same basic chemical “skeleton,” and they all have chlorine atoms as part of their make-up. Furans are similar, but have a different “skeleton”. These substances vary widely in toxicity. The one considered most toxic is referred to as 2,3,7,8-tetrachlorodibenzo-p-dioxin, or simply TCDD .
How toxic are dioxins?
Dioxins are highly toxic and can cause cancer, reproductive and developmental problems, damage to the immune system, and can interfere with hormones. Dioxins are found throughout the world in the environment , and they accumulate in food chain s , concentrating mainly in the fatty tissue of animals .
Is Agent Orange still used today?
Agent Orange was a herbicide mixture used by the U.S. military during the Vietnam War. Much of it contained a dangerous chemical contaminant called dioxin. Production of Agent Orange ended in the 1970s and is no longer in use.
What does PCB look like?
Polychlorinated biphenyls (PCBs) are a group of manmade chemicals. They are oily liquids or solids, clear to yellow in color, with no smell or taste. PCBs are very stable mixtures that are resistant to extreme temperature and pressure. PCBs were used widely in electrical equipment like capacitors and transformers.
Who invented dioxin?
In 1943, the United States Department of the Army contracted botanist and bioethicist Arthur Galston, who discovered the defoliants later used in Agent Orange, and his employer University of Illinois Urbana-Champaign to study the effects of 2,4-D and 2,4,5-T on cereal grains (including rice) and broadleaf crops.
