Pollutant focus
PM2.5, PM10, NO₂, O₃
Health-oriented pollutants are interpreted against WHO and regional reference benchmarks.
Monitoring framing
Structured benchmark context
Air-quality framing references WHO guidance and regional monitoring practice rather than a single index value.
Verified local dataset
Pending integration
Source-backed metrics will appear when the platform integrates verified city-level measurements.
