Errors of emission
Mobile source air toxics come from four sources. One: some toxics are present in fuel and are emitted into the air when the fuel evaporates or passes through the engine unburned. Benzene, for example, is a component of gasoline. Cars emit small quantities of benzene in unburned fuel, or as vapour when gasoline evaporates.
