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 (Sigma12PAHs) 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.

摘要

开展了一项初步研究，以确定德里汽油车尾气中多环芳烃的概况。为采样目的，选择了三种不同类型且不同年龄组的车辆（汽车、自动人力车和踏板车）。汽车、自动人力车（三轮车）和两轮车尾气中总多环芳烃（Σ12 种多环芳烃）的浓度分别为 27.27±2.27、28.61±3.70 和 29.81±3.57 毫克/克。与汽车和自动人力车相比，踏板车尾气中的多环芳烃水平较高。本研究中总多环芳烃浓度与其他研究相比更高。如此高的浓度可能归因于车辆年龄、驾驶条件、燃料质量和排放标准等不同参数。
