Description
To evaluate redox conditions at dredged trenches in Tokyo Bay, the concentrations of U, Th, Ce, Fe, and Mn in sediments were measured. In the Th/U-Ce/U plots, the values of Th/U and Ce/U ratios at each site gathered in different places on a same line. Therefore, it is considered that Th/U and Ce/U ratios are reflecting the redox states in different sites. The concentrations of Fe and Mn in August 2011 decreased near the surface at dredged trenches. It is presumed that their concentrations at dredged trenches are influenced by the redox conditions of the surface of sediments. (author)
