|Abstract||A better understanding of the atmospheric partitioning of PAH is necessary to determine their atmospheric processing and their impact to environmental and human health. In this work, the ambient concentrations of PAH (gas and particle phase) collected in the particulate matter less or equal than 10 ?m, PM10 of Zaragoza for one year period (2003–2004) have been analyzed in order to determine the main mechanism of PAH partitioning in Zaragoza aerosols. Three different models: the Junge adsorption model, the absorption into the organic matter model using the octanol–air (KOA) partition coefficient and the absorption into the organic matter plus the adsorption onto the soot carbon model using the soot–air (KSA) partition coefficients were applied to study the partitioning between the particle and gas phases. Experimental gas/particle partition coefficients (KP) correlated well with the sub-cooled liquid vapour pressures (P0L) of PAH but with slopes higher than the expected value of -1. Experimental Kp values, compared to the modelled ones, were better fit when both, absorption into organic matter and adsorption onto the soot carbon were considered. This fitting depended on the different types of soot obtaining better results when adsorption onto activated carbon was considered. However, the temporal variations in the partition coefficient in Zaragoza aerosols could be better explained by considering the different properties of the aerosol particles (soot type), local factors, exchangeable fraction of each PAH on aerosols and the temperature-dependence of soot–air partitioning.|
