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

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
