dioxin

 [di-ok´sin]
a highly toxic and teratogenic chlorinated hydrocarbon that is a trace contaminant in the herbicides2,4,5-T and agent orange.

di·ox·in

(dī-oks'in),
1. A ring consisting of two oxygen atoms, four CH groups, and two double bonds; the positions of the oxygen atoms are specified by prefixes, as in 1,4-dioxin.
2. Abbreviation for dibenzo[b,e][1,4]dioxin which may be visualized as an anhydride of two molecules of 1,2-benzenediol (pyrocatechol), thus forming two oxygen bridges between two benzene moieties, or as a 1,4-dioxin with a benzene ring fused to catch each of the two CH=CH groups.
3. A contaminant in the herbicide, 2,4,5-T; it is potentially toxic, teratogenic, and carcinogenic.

dioxin

(dī-ŏk′sĭn)
n.
Any of several carcinogenic, mutagenic, and teratogenic polychlorinated heterocyclic aromatic hydrocarbons that can occur as impurities in petroleum-derived herbicides and as byproducts of manufacturing chemicals and burning fuels and waste.
Any of a family of highly toxic chlorinated hydrocarbons in which 2 benzene rings are linked by 2 O2 atoms, which includes dibenzodioxins and dibenzofurans
Lab Increased PT, increased lipid levels

dioxin

Toxicology Any of a family of highly toxic chlorinated hydrocarbons Clinical In humans, intense chronic exposure causes weight loss, myalgias, insomnia, dyspnea, cold intolerance, irritability, peripheral neuropathy, hepatomegaly, hemorrhagic cystitis, chloracne, actinic elastosis, loss of libido, impotence Lab ↑ PT, ↑ lipid levels.

di·ox·in

(dī-ok'sin, dī-ok'sin)
1. A ring consisting of two oxygen atoms, four CH groups, and two double bonds; the positions of the oxygen atoms are specified by prefixes, as in 1,4-dioxin.
2. A contaminant in the herbicide, 2,4,5-T; its potential toxicity, carcinogenicity, and teratogenicity are controversial.

dioxin

a chemical byproduct of the manufacture of certain herbicides and bactericides, particularly tetrachlorodibenzo-paradioxin (TCDD), which is extremely toxic.

For example, it is instructive to compare the task of confirming the presence of low ppb levels of pentachlorinated dibenzodioxins present in a soil extract by SIM versus the Saturn II in full scan.
Burning wood releases numerous compounds, including PAHs, 1,3butadiene, polychlorinated dibenzodioxins and dibenzofurans (PCDDs/Fs), polychlorinated biphenyls (PCBs), hexachlorobenze (HxCBz), and particulate matter, among others (Gullett et al.
Saytex 8010 is a new brominated flame retardant that is said to pose no environmental, worker, or consumer health risk from the formation of brominated dibenzofurans or brominated dibenzodioxins. It has flame retardance similar to that of Saytex 102E (decabrom), which will have its use restricted under proposed European regulations.
