Talk:Polybrominated diphenyl ethers

message: Alot of info here, but maybe not only about PBDEs  www.toxichotseatmovie.com/
Several state legislatures, including Vermont and Maryland, have banned flame retardants in furniture
On May 11, 2012, The Chicago Tribune commenced publishing a five-part series that explored the decades-long campaign of profit-driven deception borne from the misleading tactics of the tobacco industry.
California’s Governor Jerry Brown directed The California Bureau of Home Furnishings to replace Technical Bulletin 117, the outdated and ineffective flammability standard followed by most furniture manufactures nationwide.
In 2014, California will have a revised fire-safety standard that, for the first time in nearly 40 years, will provide a non-toxic alternative to all consumers.  — Preceding unsigned comment added by RonPaul573e (talk • contribs) 10:46, 5 May 2015 (UTC)

message: There is a confusing mixture of PDBE and PBDE on this page. Are these 2 different animals, or just transposition?

message: Is the following sentence a conclusion of the researchers or the wikipedian's opinion?
However this source is extremely unlikely to account for the concentrations of PBDEs measured in human tissues, wildlife, household dust and common foods.

thread_title: "extremely unlikely" (main section)

message: I'd argue that this article is biased in favor of PBDEs, and someone else also seemed to notice because they added the "citation needed" tags wherever something seemed to be a little off. I'm writing a paper about PBDEs right now, and I came to wikipedia for links (as I tend to do), so I'm a little busy, but I'll try to find sources for what I can and remove what I can't find sources for later. One problem is a lack of sources on PBDEs -- but I'm calling some companies to find some stuff out; hopefully that will help. CaTigeReptile 12:16, 30 April 2007 (UTC)
replies: text: I believe you were being bothered by the same paragraph as me. It has been moved to a subsection to make it clear that it's the BFR's industry's arguments (which they still have to support with references).--Agent Fog 16:46, 7 August 2007 (UTC)
thread_title:  Neutrality? 

message: I'm tempted to remove that subsection and its contents altogether. Now that I read that paragraph again (after having isolated it in a subsection), I have concluded the following:
*The first two sentences don't contribute directly to the PBDE article, and are stated as POV.
*The third sentence repeats something already said in the introduction.
*The fourth sentence DOES HAVE something to rescue: Pressure to shift to less studied alternatives could have a negative outcome.
So, that last idea should be rescued and moved out of the subsection. The susbsection itself should be removed, because it is essentially a POV section in a scientific article. Perhaps also someone with knowledge on the subject could write an Alternatives to PBDEs section. --Agent Fog 17:58, 13 September 2007 (UTC)

message: The whole article is just lacking alot of needed information . Can someone please work on this, especially by providing information on the history and origin of this substance. Im very interested in knowing how long this stuff has been used in modern society.  —Preceding unsigned comment added by 68.108.114.107 (talk) 13:31, 20 February 2010 (UTC)
replies: text: To address this there is an interesting paper providing info on the history of use, production and components of main commercial mixtures of PBDEs  Mehran Alaee et al. (2003) An overview of commercially used brominated flame retardants, their applications, their use patterns in different countries/regions and possible modes of release. Environment International 29: 683–689 Also, the literature cited in this paper can be reviewed to improve this article. Angel670 talk 16:05, 28 February 2012 (UTC)
thread_title:  there should be a section on the HISTORY of this substance, including how long ago it was invented, how long its  been used, who invented it, etc.

thread_title:  Forest fires 

message: See the Wikipedia Dioxin section "Polychlorinated dibenzodioxins" and Dibenzofuran for references.
Most of my experience is in analysis and reporting of PCB contamination, however some of the observations are pertinent to PBDEs.
The Mechanism of Toxicity of Poly Halo Aromatics seems to be tied foremost to Cytochrome P-450 metabolism. As 2,3,7,8-tetrachlorodibenzodioxin (TCDD) is toxic at the sub PPB levels and PCBs are tested at the 100's PPM levels, many studies of PCB toxicity are diluted Dioxin. The Furan analog (2,3,7,8-tetrachlorodibenzofuran) has similar toxicity. The ether analog, 3,4,3',4' TetraChloro DiPhenyl Ether, toxicity was described in documentation about the Seveso disaster in Italy (2,4,5 D factory explosion generating Dioxin etc.). When we tested transformer oil for Bonneville Power Authority, there was documentation that arcing (oxygen activation) and overheating generated TCDD and TCDF (2,3,7,8-tetrachlorodibenzofuran). TCDD and TCDF are formed (in small quantities) industrially from pyrolysis and low temp incineration, bleaching paper, and burning wood in the presence of salt e.g. driftwood.
Similar reactions would be expected chemically from the more reactive PBDE compounds, especially in the presence of Copper in electronics. Wikipedia Bromine states "At high temperatures, organobromine compounds are easily converted to free bromine atoms"; loss of 2Br from 2,3,4,2',3',4' HexaBromo DiPhenyl Ether or HBr from 2,3,4,3',4' PentaBromo DiPhenyl Ether yields 2,3,7,8-tetrabromodibenzofuran. 
Seagoing Murex Snails make dibromoindigotin and per Bromine Organobromine compound, "Organobromides are needed and produced enzymatically from bromide by some lower life forms in the sea, particularly algae". See http://www.mendeley.com/research/hydroxylated-methoxylated-brominated-diphenyl-ethers-red-algae-ceramium-tenuicorne-blue-mussels-baltic-sea/   "Both OH-PBDEs and MeO-PBDEs are known natural products, while OH-PBDEs also may be metabolites of PBDEs."

message: Would be interesting if the article is expanded and the issue of long-range atmospheric transport of PBDEs is addressed. Thank you. Angel670 talk 16:07, 28 February 2012 (UTC)
