Variations of Pm10 Mass Concentrations and Correlations with Other Pollutants in Belgrade Urban Area

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 mu g m(3) On the roof station, a maximum daily value of 209 mu g 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 mu g m(3) During the spring campaign, the number of exceedances was three out of 22 All values during the summer campaign were below 50 mu g 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, 200
