These data are focused on the POP exchanges at the air-water interface of a high altitude lake named Muzelle lake. This lake located in the French Alps is 2105meters high and is in a protected area of the National Parc of Ecrins,far away from all direct sources of pollution. Two POP families were targeted for their different physicochemical properties:PAH and PCB. The air-water transfer studies were realized on the high-altitude lake over two summer periods (2014 and 2015). As the lake is frozen over 6 months per year,the exchanges between the atmosphere and the water take place between June and November. These dataset deal with water,sediment and atmospheric PAH concentrations in aquatic and atmospheric compartments and fluxes of atmospheric deposits and sedimentation. In these mountain environments with limited access and energy,a passive sampling strategy was chosen in the both compartments. Concentrations in water from silicone passive samplers were calculated by using methodologies and equilibre values from the literature.
