Figure 8. The range of AQI values
The AQI consists of 6 categories, each represented by a specific colour and indicating a certain
level of health concern to the public and is it shown in figure 9.
The Ambient Air Quality Standards for Mauritius reports that the safe limit for ozone is 100 micrograms per m 3 and the safe AQI value set is also 100. Therefore, the AQI itself can, indirectly, be used to measure ozone concentration in Mauritius.
