本文研究了车辆驾驶舱主要空气污染物的成份和来源。利用快速检测技术与色质联用技术,对汽车处于静止、行驶状态驾驶室及尾气处空气污染物成分进行了定性检测。结果显示,车辆在行驶或静止状态下,其驾驶舱内主要污染物以烷烃类、苯及其衍生物污染物为主。苯及其衍生物主要为燃油燃烧过程产物,在尾气中含量较高。无机类污染物以二氧化碳、一氧化碳、二氧化氮、一氧化二氮等无机气体为主。
This article studies the composition and source of the major air pollutants in the cockpit of a vehicle. Using the rapid detection technology and the chromatographic technique, the air pollutants in the cab and tail gas of the vehicle in stationary and driving conditions were qualitatively tested. The results show that the main pollutants in the cockpit of vehicles are mainly pollutants of alkanes, benzene and their derivatives when the vehicle is driving or at rest. Benzene and its derivatives are mainly products of the combustion process of fuels, with high content in the exhaust gas. Inorganic pollutants to carbon dioxide, carbon monoxide, nitrogen dioxide, nitrous oxide and other inorganic gases based.
