Summary:

In recent years, several investigators have characterized and measured hydrocarbon components, including benzene, in vehicle exhaust. This paper presents an analysis of benzene exhaust emission data reported from approximately 100 light-duty vehicles. Results indicate that on average, benzene exhaust emissions from catalyst-equipped vehicles are significantly less than those from non-catalyst vehicles. In addition, benzene exhaust emissions from 3-way catalyst vehicles appear to be significantly less than those from oxidation catalyst vehicles, on average. These observations parallel analogous average reductions in total hydrocarbons, indicating that modern catalyst-based exhaust emission controls reduce benzene emissions to approximately the same degree as they reduce total hydrocarbons. Also, benzene evaporative emissions from 3-way catalyst vehicles appear to be substantially less than those from oxidation catalyst vehicles. Finally, a benzene refueling emission rate was calculated. Its contribution to total benzene emissions appears to be very small
