Road transport emission has been on continuous rise due to revolution in the automobile industry and public mobility demand. Emissions from motor vehicles have been one of the primary pollution sources in the metropolitan area of Delhi having a noticeable impact on ambient air quality. Volatile organic compounds, polycyclic aromatic hydrocarbons and carbonyl compounds are the major organic pollutants in urban environment. This objective of this study was to estimate the emission and concentration of Benzene, Total PAHs, and Total VOCs at 36 urban transport corridors of Delhi city. After analyzing the traffic scenario as well as toxic vehicular pollutants at all the transport corridor, the highest emission and concentration of Benzene, Total PAHs, and Total VOCs was found at ITO Bridge (3.71 Kg/Day; 13.86 µg/m3), ISBT Flyover (86.22 Kg/Day; 322.12 µg/m3) and Nizamuddin Bridge (516.44 Kg/day; 1929.33 µg/m3) respectively, whereas the Auchandi Road transport corridor showed the lowest emission as well as concentration of Benzene (0.21 Kg/Day; 0.78 µg/m3) and VOCs (26.91 Kg/day; 100.53 µg/m3). Due to comparatively very less traffic and restriction on the entry of heavy vehicles at Sansad Marg transport corridor, very low emission and concentration of PAH (11.31 Kg/day; 42.27 µg/m3) was found.
