A number of epidemiological studies have demonstrated that several acute and chronic health effects are related to the urban exposure to inhalable particulate matter of aerodynamic diameter <10 mm (PM10). High concentration of O3 at the ground level is also known to have harmful effects on human health and vegetation being therefore a major environmental problem in many urban and industrial regions. In this study, concentrations of particulate matter and O3 were measured at three very urban sites of Belgrade, during 2002, and were analysed to show their temporal and spatial distribution. The influence of meteorological factors, such as temperature, relative humidity, wind speed and direction on mass and ozone concentrations, was also analysed focusing on local and regional emissions as well as on their mutual correlation. In summer episodes of exceptionally high pollution, intense photochemical reactions occurred resulting in high concentrations of fine (< 2.5 mm) particles (PM2.5) and ozone. As for the health aspects, this result is of high relevance, since the fine particles have the highest negative impact and they have the longest residence time in the atmosphere.
