Ambient air pollution continues to be a major public health issue in urban regions of developing nations. Understanding the health risks associated with air pollution exposure is crucial for framing regulation and policies concerning air pollution mitigation. This research investigated the temporal effects of the relationship between short-term exposure to ambient air pollution and non-accidental mortality using a time series analysis. Poisson regression was used to model daily non-accidental mortality counts in relation to air pollution with adjusted for temperature, humidity, seasonal and temporal trends. Natural cubic smoothing was used to address the non-linear confounding factors. A 1.74% (95% CI: 0.35 – 3.13) increase in mortality was observed per IQR increase of same-day PM2.5 exposure, and a 1.58% (95% CI: 0.18– 2.98) increase for O3. SO2 demonstrated significant associations across all lags with 5.25% (95% CI: 3.21 – 7.28) for seven-day cumulative average, while PM2.5 showed significant associations at all lags except for the 7-day lag. In the multi-pollutant model, significant associations were found between three-day lags of SO2 and PM2.5 and mortality while PM2.5 and O3 exhibited increases effects on the same day. This study emphasises the need of integration of air pollution mitigation strategies with interdisciplinary collaboration between environmental scientists, urban planners, and public health officials for sustaining public health.
