Abstract

Vehicular emissions are a major contributor to urban air pollution, necessitating continuous monitoring and assessment to formulate effective mitigation strategies. This study evaluates air pollution levels at two critical traffic divergence points along Asian Highway 47 in Indore, India—IDTL Toll Manglia and Bicholi Mardana—during the winter months of November and December 2022. The study focuses on the simultaneous measurement of Respirable Suspended Particulate Matter (RSPM - PM10), Sulfur Dioxide (SO₂), Nitrogen Dioxide (NO₂), Carbon Monoxide (CO), and Total Vehicular Pollution Load (TVPL), along with the Air Quality Index (AQI). These pollutants were selected due to their strong correlation with vehicular emissions, their adverse effects on human health, and their contribution to environmental degradation. The sampling process, conducted twice a week for one month, followed Central Pollution Control Board (CPCB) guidelines, employing gravity and absorption principles for particulate and gaseous pollutants, respectively. The results indicate a clear diurnal variation in pollutant concentrations, with significantly higher levels recorded during the evening peak hours compared to the morning period. RSPM concentrations ranged from 101.45 µg/m³ to 152.78 µg/m³ in the morning, while evening values peaked at 190.82 µg/m³ at IDTL Toll Manglia and 173.38 µg/m³ at Bicholi Mardana.
