In the last few decades, India has witnessed a sharp rise in vehicle population in all the major cities of India. Increase in both public and private transport sectors has augmented the air pollutant concentrations beyond permissible limits. Though the number of studies on vehicular pollution has increased in last few years, however, studies on assessment of personal exposure and health risk assessment in different transport mediums are limited. In Indian cities, the general commute time from home to workplace is quite high (approximately 1.5–4 h to and from home to work place). Bangalore is reported to be one among the top ten metropolitan cities in the world which is considered to be the most congested city resulting in increased commute time by several folds during peak hours. The present study provides an insight to personal exposure and health risk assessment while travelling in various transport medium such as a two wheeler (a Bike), three wheeler (an Auto) and a four wheeler (a Bus) in 2 land use patterns, i.e. commercial and industrial area. Exposure monitoring of PM5 (particulate matter with aerodynamic diameter less than 5 µm) using personal sampler (EnviroTech APM 801) was carried out considering two road maps in commercial and industrial areas for 35 days (2 samples per day during peak and non-peak hours) while travelling in auto, bus and bike. The total sampling time was 1.5–2 h in different days in each medium with the speed of vehicle maintained identical. Studies on human exposure to vehicular pollution were made under different scenarios with respect to windows (either open or close) in bus and side cover (either open or close) in auto during both peak and non-peak hours. Exposure during weekends was also investigated. In addition, chemical characterizations of PM5 for 15 elements (Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Na, Ni, Pb, Sr and Zn) were carried out using inductively coupled plasma optical electron spectroscopy, and cancer risk was assessed for carcinogenic elements.
