Abstract

Since 1976, methylcyclopentadienyl manganese tricarbonyl (MMT), an organic derivative of Mn, has been used in Canada as an anti-knock agent in unleaded gasoline. In order to evaluate the contribution of MMT to urban air pollution, the CO and NOx emissions of 10 vehicles were sampled (five filled with MMT-free gasoline, and the remaining five with MMT-added gasoline). The emissions were evaluated according to the Federal Test Procedure. The NOx and CO analysis was carried out by means of infrared spectrometry. Overall, the amount of CO emitted by the vehicles using MMT-added gasoline was twice the amount emitted by the vehicles using clear (MMT-
