Nine samples of suspended matter at the surface or bottom and 34 elements in 20 samples of substrate sediment have been used in the neutron activation analyses. Authors study sediment and suspended matter movement by using the method of element geochemistry, and conclude through synthetic analysis and processing that the movement direction of suspended matter and substrate sediment tends to converge on the central area.
