Description	The long-range atmospheric transport (LRT) of polycyclic aromatic hydrocarbons (PAHs) is not fully understood and has hardly been addressed by model studies. By model experiments the LRT of PAH emissions into air from Europe and Russia is studied testing several scenarios of gas/particle partitioning and degradability by reaction with ozone and the hydroxyl and nitrate radicals for two PAHs, benzoapyrene and fluoranthene. The model used is the atmosphere general circulation model ECHAM5 with a dynamic modal aerosol submodel, HAM, ozone and sulfur species chemistry and bidirectional mass exchange on 2D marine (ocean surface mixed layer) and terrestrial surfaces (top soil layer and vegetation surfaces).
