Daily commuting increases level of contaminants inhaled by urban community and it is influenced by mode and time of commuting. In this study, the commuters’ exposure to ambient particulate matter (PM<SUB>2.5</SUB>) and nitrogen dioxide (NO₂) was assessed during three modes of travel in six different road stretches of Chennai. The mean distance of road stretches was 25 km and the exposure to pollutants was assessed during peak hours and off-peak hours. The average travel duration was in the range of 39 to 91 min in motorbike, 83 to 140 min in car and 110 to 161 min in bus. Though there was variation on exposure to concentration in modes of transportation, the maximum exposure concentration of PM<SUB>2.5</SUB> was observed as 709 μg/m³ in bus and the minimum exposure concentration was 29 μg/m³ in closed car. Similarly, the maximum exposure concentration of NO₂ was observed to be 312 μg/m³ in bus and the minimum exposure concentration was 21 μg/m³ in car. The concentration of elements in PM<SUB>2.5</SUB> was in the order of Si > Na > Ca > Al ≥ K > S ≥ Cd, with Si and Cd concentration as 60% and < 1% of the PM<SUB>2.5</SUB> concentration.
