Business Today explains the six categories of Delhi’s Air Quality Index and why a city‑wide average can hide significant local differences.
Delhi's Air Quality Index (AQI) is split into six categories, from "Good" to "Severe", each linked to specific pollutant concentration ranges such as PM2.5, PM10, NO2 and ozone, indicating varying health risks.
Business Today notes that the overall city average often masks sharp variations across neighborhoods; traffic‑dense corridors and industrial zones typically record higher readings than the aggregate figure suggests.
Authorities recommend that residents rely on localized AQI data—available via government apps and real‑time monitoring stations—to gauge air quality accurately before planning outdoor activities or taking protective measures.
