À propos de la qualité et de la mesure de la pollution atmosphérique:

A propos des niveaux de qualité de l'air

IQANiveau de pollution de l'air Impact sur la santé
0 - 50 Bon La qualité de l'air est jugée satisfaisante, et la pollution de l'air pose peu ou pas de risque.
51 -100 Modéré Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
101-150 Mauvais pour les groupes sensibles La qualité de l'air est acceptable; Cependant, pour certains polluants, il peut y avoir un problème de santé modérée pour un très petit nombre de personnes qui sont particulièrement sensibles à la pollution de l'air.
151-200 Mauvais Tout le monde peut commencer à ressentir des effets sur la santé; les membres des groupes sensibles peuvent ressentir des effets de santé plus graves.
201-300 Très mauvais Avertissements de santé de conditions d'urgence. Toute la population est plus susceptible d'être affecté.
300+ Dangereux Alerte de santé: tout le monde peut ressentir des effets de santé plus graves.
