Abstract MD thesis. Review of the principal pollutants found in motor vehicle exhaust (CO, aromatic hydrocarbons, lead, nitrogen oxides, sulfur oxides). Based on previous investigations, this thesis attempts a comparison of the degree of poisoning hazard according to the workplace (motorways, road tunnels, underground car parks) from the results of workplace air sampling and clinical data. Underground car park attendants seem most exposed to CO (although peaks of 150ppm are found in road tunnels). Excessively high concentrations of benzopyrene (100-600mg/m3), lead (0.001-0.025mg/m3), and nitrogen oxides (25ppm) were found at motorway toll collectors' booths. Preventive measures: better tuning of engines, use of petrol with less lead content. The occupational health practitioner can play an important part in screening out subject with chronic bronchitis, emphysema, asthma or heart disorders (severe or developing).
