Abstract
Nuclear analytical techniques were applied to determine the elemental compositions of suspended and bottom sediments, collected at different sites in Haiphong harbor area (North Viet nam). The study was aimed at: 1/Understanding the origin of the sediment filling up the access channel and causing large expenditures for dredging operations. 2/Determining the background concentrations of trace elements in sediment. This would allow to detect in the future any pollution caused by the discharge of industrial wastes in the water due to the growing industrialization of the area. 3/Identifying the elements, which can be served as activatable tracers in sediment transport studies. The results obtained for the concentrations of nearly 30 elements show rather similar elemental compositions, reflecting a common origin of the sediments taken from different locations in the harbour area. The results could not allow to identify the pathway of the sediment transported to and deposited on the bottom of the access channel. Meanwhile, a considerable difference was found in the elemental compositions of the sediment and the soil taken at the nearby to the channel island bank. This would definitely exclude any hypothesis on the interrelationship between the sediment on the bottom of the channel with the soil abraded

The analysis also provides the background levels of the elements-pollutants, on the basis of which any industrial pollution in the future could be revealed.(Authors)(1 Table).}
