Abstract

V originále

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
