‘Alarm’ Level
The air quality index, determined based on the concentration of particulate matter (PM10) in one cubic meter of air, categorizes values as follows:

0-50: Clean air (green), 51-100: Moderate (yellow), 101-150: Unhealthy for sensitive groups (orange), 151-200: Unhealthy (red), 201-300: Very unhealthy (purple), 301-500: Hazardous (brown).

According to the World Health Organization (WHO), air pollution levels recorded above 100 micrograms are deemed “harmful to health,” while measurements exceeding 250 are considered to be at the “alarm” level.
