Fog and rime water samples were collected at the meteorological observatory Milešovka in February and June 2006. In the samples, the soluble and insoluble pollutant concentrations were evaluated separately and the differences between the fog and rime water samples were studied. The comparison of the fog and rime water samples indicates that the mean soluble component concentrations in the air appear to be higher during the rime events than during the fog events at Milešovka. We recorded a larger mean particle size of the insoluble compounds in the fog water samples than in those of rime water. Some elements contained in the insoluble particles like Ca, Cl, C, Cu, Ag, were present largely in fog whole others, like Fe, Al, Si, Ti, prevailed in rime. In addition to the overall evaluation, the backward air trajectories were determined for each fog/rime event and the concentrations are presented as depending on the direction of the air particle transfer.
