| Pollutant (per 10 μg/m3) |
Model type | Male | Female | < 12 | 12–65 | ≥65 |
|---|---|---|---|---|---|---|
| NO2 | NO2 + SO2 | 4.21 (3.83–4.59) | 4.27 (3.88–4.67) | 5.55 (4.84–6.27) | 3.87 (3.51–4.23) | 5.02 (4.44–5.6) |
| NO2 + O3 | 2.04 (1.8–2.29) | 2.18 (1.93–2.44) | 3.76 (3.31–4.22) | 1.83 (1.6–2.05) | 2.67 (2.3–3.05) | |
| NO2 + PM10 | 2.25 (2.0–2.51) | 2.42 (2.15–2.68) | 3.38 (2.9–3.87) | 2.07 (1.84–2.31) | 3.03 (2.64–3.41) | |
| NO2 + PM2.5 | 2.46 (2.12–2.79) | 2.6 (2.25–2.94) | 3.71 (3.09–4.34) | 2.22 (1.91–2.54) | 3.65 (3.15–4.16) |
