The quantity of dioxins near Spolana is significantly higher than the background levels in other countries. According to the US EPA, even a background level can pose a risk of cancer from 1:10000 to 1:1000, about 100 times higher than normal. [74]
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a polychlorinated dibenzo-p-dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') [3] with the chemical formula C 12 H 4 Cl 4 O 2.
Craigslist took away eBay's board representation in 2007, the year eBay launched its Kijiji online classified ads service, saying they didn't want to share potential trade secrets with a competitor.
Dioxins and dioxin-like compounds (DLCs) are a group of chemical compounds that are persistent organic pollutants (POPs) in the environment.They are mostly by-products of burning or various industrial processes or, in the case of dioxin-like PCBs and PBBs, unwanted minor components of intentionally produced mixtures.
Dibenzo-1,4-dioxin, also dibenzodioxin or dibenzo-p-dioxin (dibenzo-para-dioxin), is a polycyclic heterocyclic organic compound in which two benzene rings are connected by a 1,4-dioxin ring. Its molecular formula is C 12 H 8 O 2 .
Octachlorodibenzodioxin (can be abbreviated as OCDD or OctaCDD) is one of polychlorinated dibenzodioxins (PCDDs).. Its toxicity is similar to TCDD, but it is about 3000 times weaker.
Toxic equivalency factor (TEF) expresses the toxicity of dioxins, furans and PCBs in terms of the most toxic form of dioxin, 2,3,7,8-TCDD. [1] The toxicity of the individual congeners may vary by orders of magnitude.
Dibenzo-1,4-dioxin, also known as dibenzodioxin or dibenzo-p-dioxin (molecular formula C 12 H 8 O 2), in which two benzene rings are connected through two oxygen atoms. That is the parent compound of the dioxins (see next in which the dioxins comprise a key part of the class).
