Comparative Analysis of Recent Air Pollution Trends in India: Insights from the Two Years

This study presents a comparative analysis of hourly PM2.5 levels in Delhi from October 20 to November 3 in 2023 and 2024, highlighting significant air quality trends and pollution management strategies' effectiveness. In 2023, Delhi experienced alarming pollution levels, with the Air Quality Index (AQI) peaking at over 800, indicating a severe public health crisis that necessitated urgent interventions. Conversely, while 2024 also faced elevated PM2.5 levels, peaking at 600 on October 31, the subsequent decline in pollution levels and stabilization of the AQI below hazardous thresholds indicate a more effective response to air quality challenges. The analysis reveals a reduced duration of hazardous conditions in 2024, demonstrating the impact of enhanced pollution control measures and community engagement. Despite remaining challenges, the quicker recovery from pollution spikes underscores the effectiveness of implemented policies. These findings emphasize the importance of sustained efforts in air quality management and continuous monitoring to adapt to changing environmental conditions. As Delhi continues to confront urban air pollution, ongoing collaboration among government, industries, and communities is essential to safeguard public health and foster a healthier environment for all residents.

本研究对2023年10月20日至11月3日以及2024年同期德里PM2.5小时浓度水平进行了比较分析，着重探讨了空气质量趋势及污染管理策略实施效果。2023年，德里空气质量恶化至警钟长鸣，空气指数（AQI）峰值突破800，揭示了严重的公共卫生危机，迫切需要采取紧急干预措施。相反，虽然2024年同样面临PM2.5浓度上升，10月31日峰值达到600，但污染水平的下降及AQI低于危险阈值的稳定态势，表明对空气质量挑战的反应更加有效。分析显示，2024年危害条件持续时间缩短，彰显了强化污染控制措施及社区参与的成效。尽管仍存在挑战，但污染峰值快速恢复凸显了实施政策的有效性。这些发现强调了在空气质量管理中持续努力及持续监测以适应环境变化的重要性。随着德里继续面临城市空气污染，政府、工业及社区之间的持续合作对于保障公众健康及营造更健康的生活环境对于所有居民至关重要。
