火山排放是全球对流层气溶胶的重要来源，对地球不同时间和空间尺度的辐射收支具有重要影响。火山气溶胶还可以输送微量金属和其他污染物，对陆地生态系统和人类健康产生影响。我们在这里提供了关于当前对对流层中火山颗粒的起源和转变的理解的入门知识，涵盖它们的通量、尺寸分布、成分和形态，并重点关注硫、卤素和痕量金属化合物。这种理解对于调查火山挥发物排放对大气、环境和人类健康的影响至关重要。
Volcanic emissions represent an important source of aerosol to the global troposphere, and have important implications for the Earth’s radiation budget at various temporal and spatial scales. Volcanogenic aerosol can also transport trace metals and other pollutants, with impacts on terrestrial ecosystems and human health. We provide here a primer on the current understanding of the origins and transformations of volcanogenic particles in the troposphere, covering their fluxes, size distribution, composition and morphology, and focusing on sulfur, halogen, and trace metal compounds. Such an understanding is essential to investigations of the atmospheric, environmental and human health impacts of volcanic volatile emissions.
