Understanding iodine dynamics via sludge in Tokyo Bay
Project Period (FY)： 2019/08 - 2021/03 Investigator(s): Owari Satoko
Grant-in-Aid for Research Activity start-up Principal Investigator 19K24381
Iodine is a natural resource that is about 90 % dependent on production from Chile and Japan. To clarify where the next generation of iodine mine will develop, this study has evaluated the potential of sludge in Tokyo Bay, which is strongly affected by man-made drainage, to concentrate iodine. In Tokyo Bay, sludge with high organic matter content was developed due to the influence of artificial drainage, methane and iodine, which have high affinity with organic matter, were found in higher concentrations just below the seafloor compared to seawater.
