ROADSIDE AND IN-VEHICLE CONCENTRATIONS OF MONOAROMATIC HYDROCARBONS

Airborne concentrations of benzene, toluene, and xylenes were measured inside passenger cars being driven along major roads in Birmingham, U.K., as well as immediately outside the car and at the roadside. A comparison of concentrations measured in the car with those determined from immediately outside showed little difference, with a mean ratio for benzene of 1.17 +/- 0.34 and for toluene 1.11 +/- 0.16. The ratio of in-car to roadside concentration was 1.55 +/- 0.68 for benzene and 1.54 +/- 0.72 for toluene. Roadside concentrations were typically higher much than those measured at a background suburban monitoring station within Birmingham. Measurements of benzene and toluene in a car driven on a rural road outside the city showed very comparable in-car and outside concentrations, strengthening the conclusion that pollution inside the car is derived from pollutants outside entering with ventilation air.
