[Air pollution by motor vehicles along the freeways].
Total mass particulates and benzopyrenes have been determined to evaluate the specific pollution by vehicles on a section (6 km) of a highway. The traffic density generated an increase of 30% mass particulates in nighttime and 44% during daylight. Concentrations of benzopyrenes in air have doubled compared to the period before traffic.
