Evaluating the Environmental and Public Health Inference of COVID-19 Lockdowns: A Longitudinal Study of Air Quality in Delhi and National Capital Region (NCR)

Abstract

The COVID-19 virus has had a huge impact on communities around the world, leading to lockdowns to reduce the spread of the virus. This research paper aims to provide a detailed comparison of the impact of the lockdown on air quality in Delhi's National Capital Region (NCR). It also aims to assess the short- and long-term effects of the lockdown on residents of the Delhi National Capital Territory by analyzing various air pollutants. The research will compare pre- and post-closure conditions and explore differences in the impact of different demographics and health groups. Findings from this study can inform policymakers, urban planners, and community health officials in developing effective strategies to prevent and improve health in similar situations in the future. This research paper explores changes in air pollution, specifically PM2.5, PM₁₀, NO₂, and ozone over the four years from 2019 to 2023. These pollutants show differences and changes in air quality over time
