PAHs were measured together with inorganic air pollutants at two urban sites and one rural site in the Banja Luka area, Bosnia and Hercegovina, during 72 h in July 2008 using a high time resolution (5 samples per day) with the aim to study gas-particle partitioning, aerosol mass size distributions and to explore the potential of a higher time resolution (4 h-sampling). In the particulate phase the mass median diameters of the PAHs were found almost exclusively in the accumulation mode (0.1 to 1.0 um of size). These were larger for semivolatile PAHs than for nonvolatile PAHs. Gas particle partitioning of semivolatile PAHs was strongly influenced by temperature. The results suggest that the JungePankow model is inadequate to explain the interspecies variation and another process must be significant for phase partitioning - less temperature sensitive than adsorption. Care should be taken when interpreting slopes "m" of the type log Kp = m log pL0 plus b based on 24 h means, as these are found sensitive to the time averaging, i.e. tend to be higher than 12 h mean samples.
