Abstract
Neutron induced prompt gamma-ray analysis (PGA) and instrumental neutr on activation analysis (INAA) have been applied to the sediments colle cted from the Tama River estuary in Tokyo, Japan. The vertical distrib ution of 24 elements in the sediments was determined and the factors g overning the vertical profiles have been discussed. Major elements are distributed depending on weathering that proceeds much with increasin g depth. Cadmium is highly concentrated in the deeper layer where sulp hate ion is reduced to hydrogen sulphide. The distribution of several rare earth elements is also presented.
