Goede Lucht Kwaliteit	0-1	Air quality is considered satisfactory, and air pollution poses little or no risk
Redelijke Lucht Kwaliteit	1-2	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.
Aanvaardbare Lucht Kwaliteit	2-3	Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Slechte Lucht Kwaliteit	3-4	Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
Zeer Slechte Lucht Kwaliteit	4-5	Health alert: everyone may experience more serious health effects
Extreem Slechte Lucht Kwaliteit	> 5	Health warnings of emergency conditions. The entire population is more likely to be affected
