Talk:Volatile organic compound

From Wikipedia, the free encyclopedia

I have reorganised this page somewhat by making more sections and regrouping some of the content. I hope this has made the article more coherent. I have also heavily edited the article on phytoncides - see below. --NHSavage 22:47, 5 September 2005 (UTC)

[edit] and burning biomass such as wood

my knowledge of chemistry has became a little rusted over the years, but I can not see of burning of wood can release methane. I could agre that processes of bio-matter decompostion can be responsible for emissions of methane and sulphur dioxide etc. but wood combustion?? sorry if that is a lame comment. —Preceding unsigned comment added by 86.10.66.204 (talk) 20:52, 17 December 2007 (UTC)


[edit] phytoncides

The original text on this read "At the other hand some VOC (phytoncides) use in medicine and are the factor of the pure air for location of preventorium (sanatorium, health farm, health station) in oak or pine forests." I have done my best to put this into good English but I may have misinterpreted what 193.111.16.7 meant. If this is the case I apologise. My own POV is that this sounds like snake oil but I am not well informed enough to rewrite this in an NPOV manner. --NHSavage 22:47, 5 September 2005 (UTC)

[edit] About the CFR definition

Hi there. What's up with the CFR definition? It's very difficult to read, there are many spaces (tabs, perhaps?) and some double and triple parentheses. Could anyone help me fix this (I can't do it alone because I don't know anything about this CFR thing, so I don't know where to break lines... ) - Andycyca|say... 22:16, 24 April 2006 (UTC)

I'd vote that we plan for the future and expect these subparts to bedefined further on their own. As such since each chemical has its own use and problem list they should be seperated in a descending list for easy break out and stubbing. If we are planning for this resource to be the one stop online data depot then we need to plan for the pyramids. If there is a lot more to the story then write with the idea that others will fill in the gap at a later date.FOK SD OA 20:05, 2 September 2006 (UTC)

I felt the CFR definiton was needlessly detailed. The list was of compounds not considered VOCs under the definition, making it seem even less important to the article. I retained the text of the CFR definition, including exceptions in that text, but summarized the subsequent list of non-VOC compounds to say that the definition included a list of dozens of compounds. The citation has a link to the federal government's full definition. -Agyle 22:25, 3 September 2007 (UTC)

[edit] VOC symbols for the UK notice

[edit] Makes little to no sense

Some types of VOC (phytoncides) ... are a factor in locating some sanitoriums and health farms and in oak or pine forests.

If this is an example of deliberate gibberish, it should be deleted. If it's serious, it should be clarified. —Preceding unsigned comment added by 71.101.159.23 (talk) 16:28, 13 September 2007 (UTC)

I removed the sentence. It may have been serious, but either way I think it's too minor an aspect of VOCs to warrant inclusion in this article. -Agyle 02:27, 27 September 2007 (UTC)

[edit] Fair use rationale for Image:Voc textbox.gif

Image:Voc textbox.gif is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

[edit] benzene is considered a carcinogen

The article says, "Within the NMVOCs, the aromatic compounds benzene, toluene and xylene are suspected carcinogens and may lead to leukemia through prolonged exposure."

The statement should be stronger with regards to benzene. The Environmental Protection Agency classifies benzene as a "known human carcinogen". See for example http://www.epa.gov/ttn/atw/hlthef/benzene.html

[edit] formaldehyde emitted from skin?!?

I inserted the [verification needed] tag after "formaldehyde is emitted at a lower rate from the surface of the human body" because after reading the abstract in the citation, it seemed to me that the wiki writer mistook formaldehyde for formamide. I didn't give it a [not in citation given] because I was not able to access the full text. I also read this paper that says formaldehyde exists naturally in the human body, but it did not give any sources: It was entitled "Formaldehyde Emissions Get EWPAA Tick for Safety," a Media Release from 27 Aug. 2007 from Engineered Wood Products Association of Australia at www.paa.asn.au/NewsAndMedia/Downloads/Media%20Release%20-%20Formaldehyde%20Emissions.pdf, which I accessed on 3 May, 2008. The source is invested in plywood, so it is biased, but this is something worth looking into.Tbackman (talk) 05:58, 4 May 2008 (UTC)
