摘要:

含碘气溶胶对全球气候与环境变化有着深远的影响。已有的研究表明含碘气溶胶的形成和生长源于含碘前体物(碘及碘化物)的氧化和后续聚合过程,含碘前体物的初步氧化会形成IO、OIO等具有高度反应活性的初级碘氧化物,进一步的氧化反应产生更稳定的碘氧化物IxOy,再经过后续聚合反应形成碘氧粒子(iodine oxide particles, IOPs)。IOPs的形成机制决定了含碘气溶胶的物化特性,最终决定了环境与气候效应。然而,现有的模型研究与大气观测结果之间,甚至是不同模型研究之间常常存在分歧,这些分歧又进而导致人们在评估含碘气溶胶对全球环境和气候变化影响效应上的不确定性。详细介绍了近年来大气碘化学与含碘气溶胶形成机制的研究进展,并指出了亟待解决的问题和面临的挑战。

Abstract:

Photolysis of iodine and iodine compound in the presence of O3 has been proposed as a mechanism leading to intense iodine oxide particles (IOPs) formation, which has a profound influence on global climate change and atmospheric environment. It is believed that the formation of IOPs is involved with the production and oxidation of a series of iodine oxides (IxOy). However, the details of IOPs formation are not yet resolved, and there are still important gaps between modeling and field research, or even between different modeling work, which hinders precise evaluation of IOPs' impaction atmospheric processes, climate and human health. The main progress research on the formation of iodine oxide particles has been described and the major challenges have been discussed.

Key words: source of iodine, iodine oxides, iodine oxide particles, environment and climate effect
