A highly sensitive and specific method is described for the determination of methylcyclopentadienylmanganese tricarbonyl (MMT) in gasoline and environmental samples by gas chromatography–plasma atomic emission detection (GC–AED). The procedure is simple, rapid and free from interferences. The absolute limit of detection is 0.5 fg of MMT (0.5×10 −15 g) expressed as Mn. The precision for replicate injections ( n =5) of an MMT solution (10 pg Mn) was 2.8% relative standard deviation ( RSD ). Applications of the method to analysis of gasoline (petrol), and preliminary results of the analyses of environmental samples such as air and roadside dirt, are given. © 1997 by John Wiley & Sons, Ltd.
