[Headaches in female workers in the rubber industry exposed to benzene vapors].

173 female workers of the Rubber Plant "Stomil" exposed to petrol vapours, have been examined neurologically. The workers complained particularly often of vasomotor headaches which appeared to be much more frequent in petrol vapours-exposed workers, as compared to controls. On the other hand, subjects' age and length of employment did not affect significantly the prevalence of headache.
