Abstract

Studies of the ocean-to-atmosphere iodine enrichment are reviewed. Simulation experiments using a laboratory model set are reported. Radioactive 22Na(Na+) and 131I(I, IO3, and organo-iodine compounds) were used as tracers iodine injection from sea water into the atmosphere. For the first time a simulating experiment proved that the intensity of iodine transfer with aerosols from seawater into the atmosphere is 110 times that for Na. It is hypothesised that organically bound iodine present in seawater may play an essential (or even the leading) role in iodine enrichment of aerosols. The presented experimental data indirectly support this hypothesis.
