photochemical smog Explanation: Not sure if "COv phot" is the same as or a sub category of photochemical fog http://environnement.wallonie.be/LEGIS/air/air038.htm http://jc.um.edu.mt/envsci/Notes/atmosphere/smog2.pdf http://en.wikipedia.org/wiki/Smog -------------------------------------------------- Note added at 10 mins (2008-01-09 12:38:17 GMT) -------------------------------------------------- From the first link above: 12° « composés organiques volatils produisant des oxydants photochimiques » et "COVphot" : tous les composés organiques découlant des activités humaines, autres que le méthane, qui sont capables de produire des oxydants photochimiques par réaction avec des oxydes d'azote en présence de la lumière solaire. -------------------------------------------------- Note added at 11 mins (2008-01-09 12:39:00 GMT) -------------------------------------------------- That should be photochemical smog, not fog. |

comment, NFG Explanation: The following suggests to me that this is not photochemical smog but the COVs that, through their propensity to react photochemically, contribute to the formation of such fog (other photochemical reactions with other chemicals being possible). photoreactive COVs, COVs with high photoreactivity, etc ?
