  Rezumat:  This work presents a case study carried along a busy, heavily circulated road in an important N-W town of Romania. The objective was to assess the impact of heavy road traffic on the air quality on adjacent streets. A simple method was used for the collection of volatiles from air, in charcoal filled tubes. The analytes were desorbed in an organic solvent, then separated on a capillary column. The concentration of volatile organic atmospheric contaminants mainly originating from the exhaust gas of internal combustion engines, were determined by using GC/MS quantitative analysis methods. Particulate matter concentrations in the air along the monitored street, were determined in 9 sampling sites, using a portable detector provide with proper sensors, and applying the short duration standard methodology. The results showed that the air quality suffers from exposure to particulate matter and to engine exhaust gases.

Keywords: atmospheric pollution, engine exhaust gases, particulate matter
