We are presenting the results of magnetic susceptibility measurements carried out on PM10 filters collected at two stations in Serbia from July 1st to 31st October 2011 and compare them with those from 9 stations in Hungary, located at different settings and monitoring PM10 derived from different anthropogenic sources. As the vast majority of the magnetic grains in PM10 are derived from anthropogenic sources, it stands to reason to say that variations in magnetic susceptibility are more closely related to pollution than the mass of the dust. Comparison between susceptibilities measured on filters from Hungarian and Serbian stations (Novi Sad and Veliko Gradište) reveals that the latter are polluted similarly to Győr, a Hungarian town with fairly heavy traffic. The difference, however, is that in Győr, Sundays are less polluted than weekdays, while in the Serbian towns such trend is not observable (reason can be no camion stop). Miskolc, an industrial town with heavy traffic in NE Hungary shows twice as high susceptibilities as the previously mentioned locations, while the rest of the Hungarian stations investigated are just moderately polluted (values are only somewhat higher than those for a background station)
