Vehicular air pollution is a serious public health problem in most of metropolitan cities of the world (Mayer, 1999). Delhi, the capital city of India is one of them ranked fourth-polluted city in the world (WHO/UNEP, 1992). This paper presents an overview of vehicular exhaust emissions (VEEs) scenario in Delhi city including sources of VEEs, types of vehicular air pollutants and their formation, followed by health effects of VEEs and national ambient air quality standards for control of air quality in the Delhi city. Air quality data for three year period 1997 to 1999, at two air quality control regions (AQCRs), ie, at a major traffic intersection-income tax office (ITO) intersection (AQCR1) and at a moderately busy straight Khelgaon marg (AQCR2), in the Delhi city, obtained from Central Pollution Control Board (CPCB), Delhi has been analysed. The analysis results show highest ground level concentration of CO and NO2 during winters (November to March) while lowest during tropical monsoon period (July to September) at both the AQCRs.
