Gaseous elemental (GEM), particulate bound (PBM) and gaseous oxidised (GOM) mercury species were monitored between 2009 and 2011 at the rural monitoring site, Auchencorth Moss, Scotland using the Tekran speciation monitoring system. GEM average for the three year period was 1.40±0.19 ng m(-3) which is comparable with other northern hemisphere studies. PBM and GOM concentrations are very low in 2009 and 2010 with geometric mean (×/÷standard deviation) PBM values of 2.56 (×/÷3.44) and 0.03 (×/÷17.72) pg m(-3) and geometric mean (×/÷standard deviation) GOM values of 0.11 (×/÷4.94) and 0.09 (×/÷8.88) pg m(-3) respectively. Using wind sector analysis and air mass back trajectories, the importance of local and regional sources on speciated mercury are investigated and we show the long range contribution to GEM from continental Europe, and that the lowest levels are associated with polar and marine air masses from the north west sector.
2009 年至 2011 年期间，在苏格兰的农村监测点奥肯科思莫斯（Auchencorth Moss）使用 Tekran 形态监测系统监测了气态元素汞（GEM）、颗粒态结合汞（PBM）和气态氧化汞（GOM）。三年期间的 GEM 平均值为 1.40±0.19ng/m³，与北半球的其他研究结果相当。2009 年和 2010 年 PBM 和 GOM 浓度非常低，几何平均值（×/÷标准偏差）分别为 2.56（×/÷3.44）和 0.03（×/÷17.72）pg/m³，以及 0.11（×/÷4.94）和 0.09（×/÷8.88）pg/m³。通过风向扇区分析和空气团后轨迹，研究了当地和区域来源对形态汞的重要性，我们表明，来自欧洲大陆的长距离贡献对 GEM 很重要，而最低水平与来自西北方向的极地和海洋气团有关。
