Abstract
Th-230 and Pa-231 activities have been determined in trapped particula te matter and superficial sediments at three sites in the tropical Atl antic. The evaluation of radionuclide F/P ratios (particulate flux/pro duction in the overlying water column) shows that eastern Atlantic con tinental margins constitute an important sink for Pa-231. The removal of this radionuclide is greatly dependent on the total mass flux, whil e it is not the case for Th-230. These results strongly indicate that large amounts of trace metals may be stored in these continental margi ns.
