Estimated health impact

If this station's current PM2.5 level (22.4 µg/m³) persisted as the annual average, the Air Quality Life Index would estimate:

vs. WHO guideline (5 µg/m³)

1.71 years of life expectancy lost (≈ 624 days)

vs. India NAAQS (40 µg/m³)

0.00 years

AQLI formula: max(0, PM2.5 − baseline) × 0.098 years per µg/m³. Derived from Ebenstein et al. 2017 PNAS and Chen et al. 2013 PNAS (Greenstone et al., U Chicago EPIC). This is a long-term-exposure model applied to a live snapshot — treat it as an order-of-magnitude indication, not a personal forecast. More about this calculation.
