-	Luftqualitätswerte (AQI)	Stufen zur Bewertung der Gesundheitsgefährdung
0 - 50	Gut	Die Qualität der Luft ist zufriedenstellend. Die Luftverschmutzung stellt ein geringes oder kein Risiko dar.
51 -100	Mäßig	Die Luftqualität ist insgesamt akzeptabel. Bei manchen Schadstoffen bestehen jedoch für einen sehr kleinen Personenkreis, der außergewöhnlich empfindlich auf Luftverschmutzung reagiert, eventuell Gesundheitsbedenken.
