Comparative Analysis of Aerosol-Driven Air Pollution Across Residential, Industrial, and Traffic Zones in Delhi: A Case Study of May 2025

Kiran Rawal

Abstract: This study presents a comparative analysis of air quality in three contrasting urban zones of Delhi-Anand Vihar (traffic-dense), Mundka (industrial), and Punjabi Bagh (residential)-using PM2.5 and PM10 data collected during May 2025. The objective is to investigate spatial variations in particulate matter concentrations across different land-use types and understand the implications for public health. Data obtained from CPCB monitoring stations was analyzed to determine daily and monthly averages, identify pollution peaks, and observe trends. Initial findings reveal that Punjabi Bagh recorded the highest PM2.5 levels, while Mundka exhibited extreme PM10 spikes due to industrial activity. The results highlight the need for targeted air pollution control strategies tailored to each area?s environmental dynamics.
