La dénomination de «smog photochimique oxydant» est mauvaise pour caractériser le phénomène puisque la définition précise qu'il est sans rapport avec la fumée [...] C'est la raison pour laquelle il est préférable de parler de «brouillard photochimique oxydant». 3, record 1, French, - smog%20photochimique
Record number: 1, Textual support number: 2 OBS
Malgré la recommandation d’utiliser «brouillard» plutôt que «smog», c’est ce dernier qui s’est implanté dans l’usage; la proposition de «fumard» (Analyse des gaz, étalonnage et mesure, qualité de l’air, dosage des gaz et des produits - code de source : AFNOR-34, 1983, p. 341) n’a pas eu plus de succès. 7, record 1, French, - smog%20photochimique

État de l’atmosphère caractérisé par la présence simultanée de polluants gazeux ou vésiculaires à propriétés acides et d’un aérosol de fumées retenus dans un brouillard. Le smog acide a pour origine les produits de combustion des foyers fixes. 2, record 3, French, - smog%20acide

Il peut arriver que le dioxyde de soufre se transforme partiellement en trioxyde, donc en acide sulfurique. Pour que cette transformation puisse avoir lieu, il faut que deux conditions soient remplies : l’une concerne l’existence d’une grande concentration de SO2 mais aussi de particules diverses; l’autre est du domaine météorologique et correspond à la présence simultanée d’un brouillard, c’est-à-dire d’un aérosol de microgouttelettes d’eau. [...] On voit que c’est à la présence de ce smog, véritable aérosol d’acide sulfurique, que sont imputables les grands accidents de pollution, tel celui qui a endeuillé Londres en 1952. Ce smog sulfurique est appelé «smog acide» pour le distinguer du «smog oxydant». 2, record 3, French, - smog%20acide
