Delhi AQI borders on ‘poor’ as winter approaches, dropping air quality a cause for alarm

The AQI reading is categorised as Good (0-50), Satisfactory (51-100), Moderately Polluted (101-200), Poor (201-300), Very Poor (301-400), and Severe (401-500). Thus, higher the AQI reading, the unhealthier it gets to breathe.

These categories are arrived at after evaluating various parameters. The most prominent among these is the particulate matter (PM) 2.5 pollutant, which is very fine and easy to breathe in. This causes the most harm to humans. As per the World Health Organization, “Exposure to PM2.5 can cause diseases both to our cardiovascular and respiratory system, provoking, for example stroke, lung cancer and chronic obstructive pulmonary disease (COPD).”

The permissible limit for PM 2.5 set by WHO is 15 µg/m³.
