Popis: Samples of PM10 were collected over a 12 month period at two sites approximately 5 km apart. Site 1 was an urban site in the center of the city of Rijeka, Croatia, and Site 2 was an industrial site in the proximity of a shipyard, located in the southeastwards direction from the city. No significant differences in airborne concentrations of PM10 or secondary inorganic ions were found between the two sites. Therefore, the sampling continued only at Site 1. The dominant airborne compound was ammonium sulfate, being approximately six times more abundant in the summer (S) months than ammonium nitrate. This ratio was lower in the winter (W) months, being approximately 1.5 at both sites. Seasonal distribution of secondary inorganic aerosols (SIA), particularly SO 2− is emphasized in 2008–2009 with W/S
