1. The unsaturated six-membered heterocycle having four carbon atoms, two oxygen atoms, and two double bonds (molecular formula C₄H₄O₂); 1,2-dioxin and 1,4-dioxin.

চারটি কার্বন পরমাণু, দুটি অক্সিজেন পরমাণু এবং দুটি ডাবল বন্ড (আণবিক সূত্র C₄H₄O₂) সম্বলিত অসম্পৃক্ত ছয় সদস্য বিশিষ্ট হেটেরোসাইকেল; 1,2-ডাইঅক্সিন এবং 1,4-ডাইঅক্সিন।

1. Dioxin is a specific organic unsaturated non-antiaromatic six-membered ring compound with a chemical formula of C4H4O2. However, the term dioxin is used generically by most authorities to include chlorinated dioxins with furans and many derivative compounds as a complex of at least 75 ubiquitous and environmentally persistent organochlorine compounds, of variable toxicity.

2. The parent compound dibenzo-1,4-dioxin or dibenzo-p-dioxin (molecular formula C₁₂H₈O₂), in which two benzene rings are connected through two oxygen atoms; dibenzodioxin, oxanthrene.

প্যারেন্ট যৌগ dibenzo-1,4-ডাইঅক্সিন বা dibenzo-p-ডাইঅক্সিন (আণবিক সূত্র C₁₂H₈O₂), যেখানে দুটি বেনজিন রিং দুটি অক্সিজেন পরমাণুর মাধ্যমে সংযুক্ত থাকে; ডিবেনজোডিঅক্সিন, অক্সানথ্রিন।

1. Dioxins are not a single chemical. They are a family of chemicals that contain two benzene rings connected by a pair of oxygen molecules. When chlorine atoms are connected to the benzene rings, we have a chlorinated dioxin. The particular chlorinated dioxin of greatest interest and concern is 2,3,7,8-tetrachlorodibenzo-p-dioxin (generally abbreviated TCDD).

3. Any of a broad range of toxic or carcinogenic halogenated polycyclic compounds that occur as byproducts of herbicides.

বিষাক্ত বা কার্সিনোজেনিক হ্যালোজেনেটেড পলিসাইক্লিক যৌগগুলির একটি বিস্তৃত পরিসরের যে কোনও একটি যা হার্বিসাইডের উপজাত হিসাবে ঘটে।

1. Dioxins are polychlorinated isomers that form as by-products either during combustion of waste products or afterward in the incinerator stack. They include dibenzo-dioxins (PCDD), dibenzofurans (PCDF), and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). 2,3,7,8-TCDD is one of the extremely carcinogenic groups of dioxin compounds. A risk of exposure to humans occurs once dioxin compounds are released from the stack of the incinerator and are transported by the wind elsewhere.

2. EPA [the Environmental Protection Agency] characterizes 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) as a Human Carcinogen based on weight of evidence and characterizes other dioxins, furans, and PCBs [polychlorinated biphenyls] as Likely Human Carcinogens. The toxicity of all of the dioxin, furan, and PCB congeners considered in this analysis is based on the toxicity of the most highly characterized congener, 2,3,7,8-TCDD.

3. Poisonous residues carelessly treated today can produce calamities miles away and decades later. One example is dioxin, a waste left behind in factories after the production of hexachlorophene, a potent antiseptic. Dioxins are lethal, capable of killing people in concentrations as diluted as one part in a million. Oils containing discarded dioxins have been sprayed on horse farms in Missouri to control dust. Horses subsequently died.

4. The detection of dioxin (specifically, the 2,3,7,8-tetrachlorodibenzo-pdioxin TCDD) in 2,4,5-T raised the question whether dioxin might be present in other herbicides.

5. [page 6] Dioxins in food and the environment hae been intensively studied over the past twenty years. The term ‘dioxins’ has come to be used for polychlorinated dibenzo-p-dioxins and in some cases also polychlorinated dibenzofurans. [page 7] The sources of food contamination with dioxins are now known to be many more than was originally asserted when claims were made that incinerators were the main source of dioxins in the environment. Indeed known sources of dioxins now include vehicle exhausts, domestic coal fires, manufacture and use of organic chemicals, and metallurgical processors.
