Talk:Benzopyrene

Duplicate?

There is an article Benzo(a)pyrene, which seems to refer to the same thing, but I'm no chemist - can somebody confirm? Stephan Matthiesen (talk) 17:59, 4 February 2010 (UTC)

This is exactly an article on Benzo(a)pyrene. Benzopyrene is a non-specific way of referring to various pyrene+benzene-ring structures with different properties. This should be merged. Jed (talk) 16:03, 17 February 2010 (UTC)

FWIW - At the moment I would think the present benzopyrene Wikipedia article should be preserved and not merged - benzopyrene is a general organic chemical classification term for a group of polycyclic hydrocarbons that includes two IARC-listed chemical carcinogens: ie, benzo[a]pyrene (a Group 1 carcinogen) and benzo[e]pyene (a Group 3 carcinogen) - I would think the three present Wikipedia articles (specifically, benzopyrene, benzo[a]pyrene, benzo[e]pyene) help clarify the chemical terms involved and all three Wikipedia articles continue to be useful - including the present benzopyrene Wikipedia article.

Four rings or five?

I thought that this compound had FIVE rings, not four. This article also needs grammatical checking and cleanup. Thomas.Hedden (talk) 01:22, 30 April 2009 (UTC)

Benzopyrene versus Benzo(a)pyrene

I believe at the least in german speaking areas, there is a (a) between the o and p. I never understood why. Could someone explain this part? Right now I am not even certain whether this is in the english word either; if you do a google search you can sometimes see the weird (a) there. 2A02:8388:1641:5500:8207:8CE:DF2:AB90 (talk) 19:22, 31 January 2023 (UTC)
