Rime and hoarfrost samples were collected in Gdańsk in northern Poland, and Działdowo in central Poland during winter 2003/2004 and analyzed for major ions. Analysis of the correlations between co-occurring ions confirmed the significant impact of the location of the sampling site (sea coast). For all analyzed ions, the concentrations of hoarfrost samples collected in Gdańsk were higher than those of hoarfrost samples collected in Działdowo at the same time. The concentrations of ions in rime were observed to be less than the ion concentrations in the hoarfrost samples. The high levels of pollution concentration present in the hoarfrost samples compared to the other forms of precipitation are related to the hoarfrost crystalline lattice texture.
