With the use of accelerator‐based PIXE (particle induced x‐ray emission) elemental analysis technique systematic investigation of aerosol samples have been performed in the Institute of Nuclear Research of the Hungarian Academy of Sciences for 15 years. In continuation of this research, we observe the short‐term time variation of the inorganic elemental components and the elemental mass size distributions in the spring of 2007, at the end of the heating season. Aerosol sampling campaigns were carried out with a PIXE International continuous streaker sampler (PM 10 ) and a 9‐stage cascade impactor in a downtown site of Debrecen. Meteorological data were recorded simultaneously with aerosol sampling. Another campaign was carried out with 2‐stage nuclepore samplers (PM 2.5 and PM 2.5−10 ) in the same downtown and an outskirt site of the city. The short‐time variation of urban aerosol combined with meteorological data and with mass size distribution serves as a basis to reach a better understanding of the aerosol sources and receptor areas, to select single episodes, to follow the evolution of aerosol, and to make a better estimate on the health impact.
