## Pollutants

| Pollutant | Value | Unit |
|---|---|---|
| PM2.5 | 33.07 | µg/m³ |
| PM10 | 87.99 | µg/m³ |
| NO₂ | 17.02 | µg/m³ |
| SO₂ | 15.42 | µg/m³ |
| O₃ | 21.9 | µg/m³ |
| NH₃ | 12.16 | µg/m³ |

## Estimated health impact (AQLI)

If this PM2.5 level (33.07 µg/m³) persisted as the annual average, the Air Quality Life Index estimates **2.75 years** of life expectancy lost vs. the WHO 5 µg/m³ guideline.

Formula: `max(0, PM2.5 − 5) × 0.098 years`. From Ebenstein et al. 2017 PNAS and Greenstone & Fan 2018 (U Chicago EPIC, [aqli.epic.uchicago.edu](https://aqli.epic.uchicago.edu)). This is a long-term exposure model applied to a live snapshot. Treat as an order-of-magnitude indication.
