    In this article, we have studied air pollutants in the exhaust gas of vehicle using laser mass spectromety, which is characteristic of high sensitivity, high selectivity, multi-component and on-line real-time analysis. Using this method, we find that the concentration of aromatic substances in the exhaust gas of vehicle of low gear status is much more than that of speed-up status.
