Descrição: European alpine lake systems are used as indicators of air quality over the continent. Preliminary data showed high polycyclic aromatic hydrocarbons (PAH) loads in the High Tatras (Eastern Europe) in comparison to other mountain regions. Here, insight on the spatial distribution of PAH is provided from analysis of top-core sediments of 27 alpine lakes distributed along the High Tatras. Top-core sediment concentrations were higher than those in deep-cores, and they were higher than those observed in other European high mountain regions. The PAH profiles were uniform and comparable to those observed in aerosols and snow, indicating that atmospheric deposition was the predominant PAH input pathway to the lakes. Good agreement between estimated atmospheric deposition and sedimentation fluxes was observed. However, in several lakes in the western range higher sediment fluxes may correspond to higher PAH depositions levels. The higher concentrations may also reflect inputs from potential emission source areas. ► Sedimentary PAH loads in alpine lakes from High Tatras (Eastern Europe) were higher than in other European mountain regions. ► Sediments PAH profiles comparable to aerosol and snow deposition profiles. ► Positive correlation between PAH atmospheric deposition and sedimentary fluxes. High sedimentary PAH loads were observed in alpine lakes in the High Tatras (Eastern Europe) which are related to high PAH atmospheric deposition fluxes.
