In this paper, we present the PM10 levels measured at an urban residential background site in New Belgrade, in Omladinskih Brigada Street, at 15 m height (roof). The aerosol samples were collected using a European standard sampler, in four seasonal campaigns conducted in autumn: Nov. 13-Dec. 03, 2007, winter: Feb. 07-28, 2008, spring: May 06-28, 2008 and summer: July 17- -August 15, 2008. The results were compared with PM10 mass concentrations measured with a Horiba automatic station at street level, at the same sampling site and at three more sites within the Belgrade municipal monitoring network. The results show that the PM10 values in the Belgrade urban area were high during autumn and winter campaigns (heating season) with a number of samples exceeding the 24-h limit value of 50 μg m-3. On the roof station, a maximum daily value of 209 μg m-3 was measured in the autumn campaign, with 14 values out of 20 measurements exceeding the 24-h limit. In winter, 14 out of 19 measurements exceeded the limit, with a maximum value of 196 μg m-3. During the spring campaign, the number of exceedances was three out of 22. All values during the summer campaign were below 50 μg m-3. The roof station equipped with the European Standard instrument showed systematically higher values than the street-level automatic monitor. PM10 values at all sites followed the same trend. The highest concentrations at all monitoring sites were observed during the autumn, Nov. 20-25, 2007, and winter, Feb. 19-23, 2008.
