Benzene emissions from passenger cars.

The losses of benzene into the atmosphere from three typical European passenger cars during average daily use are characterized. Three sources of loss are identified: losses during refuelling, evaporation from fuel systems and emissions in exhaust gases. The relative contributions of these sources are discussed and the report evaluates the effectiveness of various alternative means of control, including regulating the composition of motor gasoline by controlling the benzene content, and fitting control devices to passenger cars.
