Anthropogenic iodine-129 has entered into the iodine dynamic system on the earth quite recently compared to the time scale of global iodine circulation. In some special site, like soil and surface seawater, iodien-129 and iodine-127 might not be chemically mixed well. In this study will discuss about the dynamics of iodine-127 and iodine-129 separately based on the data of speciation analysis in seawater.
