Antimony (Sb) concentrations were measured in wet atmospheric deposition at 10 high-elevation sites in the Czech Republic (Central Europe) during three winter seasons (2009-2011). Soluble and insoluble Sb forms were quantified in snow (vertical deposition) and rime (horizontal deposition) on mountain summits located equidistantly near the Czech borders with Austria, Germany and Poland. The highest Sb concentrations were found in the soluble form in rime (0.47 μg L), while the lowest Sb concentrations were those in the insoluble form in snow (0.017 μg L). The estimated average Sb deposition rate in Central Europe amounted to 1.3. 10 g m yr. Most Sb was deposited in the soluble form in snow (7.9. 10 g m yr), followed by the soluble form in rime (3.5. 10 g m yr). The corresponding insoluble fraction contained less Sb, namely 1.2. 10 g m yr in snow and 2.3. 10 g m yr in rime. The average Sb deposition in Central Europe, measured at an altitude of 1000 m a.s.l., was by six orders of magnitude higher compared to Sb deposition in the Arctic (7. 10 g m yr), and by four orders of magnitude lower compared to Sb deposition in a Sb-Hg mining district in China (7 g m yr). Using the HYSPLIT model, backward trajectories of air masses indicated that the Sb sources were predominantly situated in Upper and Lower Silesia.
在捷克共和国（中欧）的 10 个高海拔地区，在三个冬季（2009-2011 年）期间对湿大气沉降中的锑（Sb）浓度进行了测量。在位于捷克与奥地利、德国和波兰边境附近等距的山顶的雪（垂直沉积）和霜（水平沉积）中定量了可溶性和不溶性 Sb 形态。在霜中发现可溶性 Sb 形式的 Sb 浓度最高（0.47μg L），而在雪中发现不溶性 Sb 形式的 Sb 浓度最低（0.017μg L）。中欧的估计平均 Sb 沉积速率为 1.3.10g m yr。大部分 Sb 以可溶性形式沉积在雪中（7.9.10g m yr），其次是可溶性形式在霜中（3.5.10g m yr）。相应的不溶性部分含有较少的 Sb，即在雪中为 1.2.10g m yr，在霜中为 2.3.10g m yr。在中欧，在海拔 1000 米处测量的 Sb 沉积量比北极的 Sb 沉积量高六个数量级（7.10g m yr），比中国 Sb-Hg 矿区的 Sb 沉积量低四个数量级（7g m yr）。使用 HYSPLIT 模型，空气团的后向轨迹表明 Sb 源主要位于上西里西亚和下西里西亚。
