The current knowledge in primary and secondary marine aerosol formation is reviewed. For primary marine aerosol source functions, recent source functions have demonstrated a significant flux of submicrometre particles down to radii of 20 nm. Moreover, the source functions derived from different techniques up to 10 microm have come within a factor of two of each other. For secondary marine aerosol formation, recent advances have identified iodine oxides and isoprene oxidation products, in addition to sulphuric acid, as contributing to formation and growth, although the exact roles remains to be determined. While a multistep process seems to be required, isoprene oxidation products are more likely to participate in growth and sulphuric acid is more likely to participate in nucleation. Iodine oxides are likely to participate in both nucleation and growth.
本文综述了海洋一次和二次气溶胶形成的现有知识。对于海洋一次气溶胶源函数，近期的源函数表明，半径低至20纳米的亚微米颗粒通量显著。此外，通过不同技术得出的10微米以下的源函数彼此相差不超过两倍。对于海洋二次气溶胶的形成，除硫酸外，近期的研究进展还确定了碘氧化物和异戊二烯氧化产物对气溶胶的形成和增长有贡献，不过其确切作用仍有待确定。虽然似乎需要一个多步骤过程，但异戊二烯氧化产物更有可能参与增长过程，而硫酸更有可能参与成核过程。碘氧化物可能同时参与成核和增长过程。
