Polycyclic aromatic hydrocarbons (PAHs) were measured together with inorganic air pollutants at two urban sites and one rural background 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 1-1 0 mu m of size) These were larger for semivolatile PAHs than for non-volatile PAHs Gas-particle partitioning of semivolatile PAHs was strongly influenced by temperature The results suggest that the Junge-Pankow model is Inadequate to explain the inter-species variation and another process must be significant for phase partitioning which is less temperature sensitive than adsorption Care should be taken when interpreting slopes m of plots of the type log K(p) = m log p(L)(0) + b based on 24 h means as these are found sensitive to the time averaging I e tend to be higher than when based on 12 h-mean samples (C) 2010 Elsevier Ltd All rights reserved
