大气海盐和卤素循环在大气科学和化学中起着重要的作用，包括云过程和南极对流层的氧化能力。本文回顾并总结了与南极海盐和卤素化学相关的当前知识。首先，介绍了海盐气溶胶（SSA）的季节变化和粒径分布。第二，SSA的起源和海冰和南极大陆冰盖上的海盐分馏介绍和讨论。第三，我们讨论SSA从冰冻圈释放。第四，我们目前SSA分散在南极对流层和运输到内陆地区。第五，非均相反应的SSA作为源的活性卤素物种和它们与大气化学的关系进行了展示和讨论。最后，我们试图提出一个展望，以获得更好的知识有关的海盐和卤素化学及其对南极和北极的影响。
Atmospheric sea-salt and halogen cycles play important roles in atmospheric science and chemistry including cloud processes and oxidation capacity in the Antarctic troposphere. This paper presents a review and summarizes current knowledge related to sea-salt and halogen chemistry in the Antarctic. First, presented are the seasonal variations and size distribution of sea-salt aerosols (SSAs). Second, SSA origins and sea-salt fractionation on sea-ice and ice sheets on the Antarctic continent are presented and discussed. Third, we discuss SSA release from the cryosphere. Fourth, we present SSA dispersion in the Antarctic troposphere and transport into inland areas. Fifth, heterogeneous reactions on SSAs as a source of reactive halogen species and their relationship with atmospheric chemistry are shown and discussed. Finally, we attempt to propose an outlook for obtaining better knowledge related to sea-salt and halogen chemistry and their effects on the Antarctic and the Arctic.
