| Abstract: | A preliminary study to determine the profile of PAHs in the exhaust of gasoline vehicles in Delhi was conducted. Three different
types of vehicles (cars, autorickshaws and scooters) were selected with different age groups for sampling purpose. The concentration
of Total PAHs (Σ12PAHs) was found to be 27.27 ± 2.27, 28.61 ± 3.70 and 29.81 ± 3.57 mg/g in the exhaust of cars, auto- rickshaws (three wheelers)
and two wheelers, respectively. The levels of PAHs were found to be high in scooter exhaust as compared to that of cars and
autorickshaws. The total PAHs concentration in the present study was found to be higher as compared to other studies. Such
a high concentration could be attributed to different parameters like the age of the vehicles, driving conditions, the fuel
quality and the emission standards. |
