PAH measurements in atmospheric and aquatic compartments:concentrations and fluxes during unglaciazed periodduring two years - Data from an high altitude lake - Muzelle lake - 2014 and 2015

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.本数据集聚焦于坐落于法国阿尔卑斯山区的穆泽勒湖（Muzelle Lake）气-水界面的持久性有机污染物（Persistent Organic Pollutants，POP）交换过程。该湖泊海拔2105米，地处埃克兰国家公园（National Parc of Ecrins）的保护区内，远离所有直接污染源。研究选取两类具有不同理化性质的持久性有机污染物家族：多环芳烃（Polycyclic Aromatic Hydrocarbons，PAH）与多氯联苯（Polychlorinated Biphenyls，PCB）作为目标污染物。气-水界面迁移研究于该高海拔湖泊开展，覆盖2014年与2015年两个夏季时段。由于该湖泊每年封冻时长超过6个月，大气与水体间的污染物交换仅发生于6月至11月之间。本数据集涵盖水生与大气环境介质中的水体、沉积物及大气中的多环芳烃浓度数据，以及大气沉降与沉积物沉降的通量数据。鉴于该山地环境交通与能源供给均较为有限，研究团队在两类环境介质中均采用了被动采样策略。通过引用文献中的方法学与平衡参数，计算得到硅基被动采样器采集的水体中污染物浓度。
