| NO₂ | 65.9 | µg/m³ |

## Estimated health impact (AQLI)

If this PM2.5 level (49 µg/m³) persisted as the annual average, the Air Quality Life Index estimates **4.31 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.
