Abstract

Based on an estimated global fuel consumption of 2.57 × 1015g(C) y−1 and the assumption thatthe fossil fuel burned in Austria is globallyrepresentative, an upper limit of 0.021 (+150%, −50%)Tg y−1 for global CH3CN emission dueto fossil fuel burning was obtained from the relativeenhancement of the concentrations of toluene, benzene,and acetonitrile (methyl cyanide) during strong,short-term traffic pollution. This is less than 6% ofthe total global budget of CH3CN, which is dominatedby an emission rate of 0.8 Tg y−1 from biomassburning.
