In the presence of excess chlorite, the iodine is oxidized further to iodate according to the following reaction: [] 5ClO2−+2I2+2H2O→5Cl−+4IO3−+4H+

Iodine comes from the mineral sodium iodate (NaIQ3) and seaweed. It is used for sterilization and treatment of thyroid problems. Iodine vapor (I2) is a strong irritant and corrosive chemical, and is more dangerous than chlorine or bromine. In large concentrations in the air, iodine can cause pulmonary edema. Inhalation of iodine vapor causes epiphora, tightness in the chest, sore throat, and headache. Large doses result in pulmonary problems similar to the chlorine exposure. Excess iodine can suppress the thyroid gland. The TLV value of iodine is 0.1 ppm, corresponding to 0.1 mg/m3.893

By the action of excess bromine, bromine-iodide decomposes, and iodine is oxidized to hydrogen iodate: BrI+2Br2+3H2O=HIO3+5HBr

Iodine is an essential element for many organisms, and iodide (I−), which is one of the chemical forms of iodine available in the ocean, is absorbed by phytoplankton [12]. Iodine in seawater exists as iodide, iodate and organic iodine. The form of inorganic iodine (iodide and iodate) depends on redox environment in the seawater [13,14]. It is reported iodate can be reduce by marine bacteria [15]. It is generally known that the average concentration of total iodine in oceanic seawater is around 450 nM [15–21]. Because phytoplankton supports biological production in the ocean, it is important to reveal the behavior of iodide in the Chukchi Sea and Bering Sea in order to better understand the nutrient provision process in these areas. If the result of observations suggests that the Chukchi Sea and Bering sea are iodide−producing areas, 129I will easily concentrate in marine organisms especially when high 129I concentration water flows into the Chukchi Sea and Bering Sea from Europe. Revealing the distribution of iodide in the Chukchi Sea and Bering Sea is important to understand the process by which marine organisms accumulate 129I released from the European Nuclear reprocessing sites.
