Anthropogenic release of atmospheric iodine is believed to be negligible, although methyl iodide (CH3I) has been licensed as a pesticide in some countries as a replacement for the stratospheric ozone-destroying methyl bromide (CH3Br). There are numerous biological pathways for production of volatile iodine compounds by marine ecosystems. These include methylation of iodine by marine microalgae (phytoplankton) and by a wide variety of aerobic marine bacteria, production of polyiodinated organic compounds from phytoplankton-containing haloperoxidase enzymes, and production from natural marine aggregates comprising a host of materials including phytoplankton and bacteria. CH3I can be produced from sunlit irradiation of seawater. The initial source of iodine is postulated to be volatile organic compounds produced in the marginal ice zone (MIZ) and deposited to the snow pack during transport inland.
