  Rezumat:   Fine particles concentration was monitored in Cluj-Napoca through a series of 12-24 hours measurements, using a direct-reading instrument, the DustTrak aerosol monitor, model 8520. In order to highlight areas with different types of exposure (both those that show a high risk for health, and those with a low risk), the measurements were carried out in several neighborhoods with a different air quality (Zorilor, Andrei Mureşanu, Gruia, Mănăştur and Grigorescu). The results showed that the variability in time and space of the fine particles (PM2.5) concentrations depend on many factors. Among these factors, based on correlations, the most significant are both the wind direction and speed, and the proximity to the highways. In most cases, the averages we obtained exceeded the limit set on 25μg/m3 according to World Health Organization and European legislation. Therefore the exposure to concentrations above the permissible value raged from 40-100%.

Key words: PM2.5, urban air quality, exposure, health risk
