Advanced statistical analysis of air quality and its health impacts in India: Quantifying significance by detangling weather-driven effects.

ABSTRACT: Air quality has emerged as a significant concern due to its direct impact on human health. Over recent decades, India has witnessed a marked deterioration in air quality due to rising anthropogenic emissions and climate change. The COVID-19 lockdown offered a unique opportunity to examine air pollutant reductions under restricted human activities. This study conducted a long-term analysis of air quality in five major Indian cities-Delhi, Kolkata, Bengaluru, Hyderabad, and Visakhapatnam-by analysing variations in PM_2.5, PM₁₀, NOx, NH₃, SO₂, CO, and O₃, incorporating a de-weathering strategy to isolate meteorological influences. In Delhi, we observed significant reductions in PM₁₀ (92.50-136.70 μg/m³), NOx (62.13-151.91 ppb),
