Industrial activities: Dioxin is not produced or used commercially in the United States. It is a contaminant formed during the production of some chlorinated organic compounds, including a few herbicides such as Silvex.

Herbicide: This was famously used in the Vietnam war in a perhaps-ill-advised attempt to destroy the environment and make enemy fighters visible; a contaminant caused chloracne. Politicians have become involved with the difficult scientific question of whether and to what extent the chemical has caused long-term health problems in soldiers and the unborn. The "dioxin" that most people mean when they just say "dioxin" is 2,2',3,3'-tetrachlorodiphenyldioxin, which has a molecular formula of C12H4O2Cl4. Class of chemical compounds. Dioxins and dioxin-like compounds ( DLCs) are a group of chemical compounds that are persistent environmental pollutants (POPs). Some of them are highly toxic, but the toxicity among them varies 30,000-fold.

Dioxin definition is - any of several persistent toxic heterocyclic hydrocarbons that occur especially as by-products of various industrial processes (such as 

Almost every living creature has been exposed to dioxins or dioxin-like compounds (DLCs). This site contains all of EPA's information on the chemical known as 2,3,7,8-tetrachlorodibenzo-p-dioxin, which is more commonly referred to as "dioxin." Some of the most troubling questions about dioxin concern the use of Agent Orange during the Vietnam War (a civil war between communist North Vietnam and noncommunist South Vietnam, fought mainly in the 1960s and 1970s; the United States began bombarding the North in 1964, but U.S. troops were withdrawn in 1973, shortly before the North's victory).

Disposable diapers are also made from wood pulp-based products, so we also compared exposure to dioxins through the use of disposable diapers to the total dioxin exposure in infants. We performed an initial screening-level estimate of the dioxin expo-

We investigated for the first time the dietary intake of these compounds in infants living in Greece. In the  12 Jun 2014 Dioxins refer to a group of toxic chemical compounds that share certain chemical structures and biological characteristics. Dioxins can be  3 Nov 2009 More and more studies of prenatal exposures to dioxins and similar chemicals are adding support for these associations.

Because dioxins refer to such a broad class of compounds that vary widely in toxicity, the concept of toxic equivalency factor (TEF) has been developed to facilitate risk assessment and regulatory control. When they're combined, an unwanted byproduct -- a dioxin called TCDD -- is formed. The EPA calls it a carcinogen (something that causes cancer).

They are grouped together, because their mechanism of action is the same. The "dioxin" that most people mean when they just say "dioxin" is 2,2',3,3'-tetrachlorodiphenyldioxin, which has a molecular formula of C12H4O2Cl4.

During the Vietnam War, the United States used helicopters to drop Agent Orange Dioxin, also called polychlorinated dibenzodioxin, any of a group of aromatic hydrocarbon compounds known to be environmental pollutants that are generated as undesirable by-products in the manufacture of herbicides, disinfectants, and other agents. In popular terminology, dioxin has become a synonym for one specific dioxin, Dioxin is a general name for a large group of chemical compounds with similar structure. These compounds are made up of carbon, oxygen, hydrogen and chlorine atoms. The number of the chlorine atoms and their positions in the dioxin molecule are what determines the toxicity of different dioxins.

We were even aware that the ‘military’ formulation had a higher dioxin concentration than the ‘civilian’ version due to the lower cost and speed of manufacture. However, because the material was to be used on the ‘enemy,’ none of us were overly concerned.
