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.

南极的大气海盐和卤素循环。

大气中的海盐和卤素循环在大气科学和化学中起着重要作用，包括南极对流层的云过程和氧化能力。本文提出了一个综述，并总结了有关南极海盐和卤素化学的最新知识。首先，介绍了海盐气溶胶（SSA）的季节变化和大小分布。其次，介绍并讨论了南极大陆架的起源和南极海冰和冰盖上的海盐分馏。第三，我们讨论从冰冻圈释放SSA。第四，我们介绍了SSA在南极对流层中的扩散以及向内陆地区的运输。第五，显示并讨论了作为活性卤素物质来源的SSA的异相反应及其与大气化学的关系。最后，
